the meanest, cruellest, most heinous crime. >> i don't know that i'll ever get over it. >> reporter: they seemed the ultimate power couple. >> they seemed like they were traveling on all the secret missions. >> he had all the medals silver star, a purple heart. >> she told me she would be travelling on secret missions. >> did they have something to hide? >> we started doing surveillance. maybe we

>> i'm thinking to myself, this can't be true. >> you're just like in disbelief. >> what had happened to her last husband? >> it's very evil. >> the hurt. the anger. it makes you question everybody. it seems alive somehow. here in the foothills of tennessee's appalachians. the creeping tendrils of mountain mist, that snake and swirl like lies. there's gold in there somewhere, so they say. the sort of place where you could strike it rich. or maybe a

>> very scary. >> shocking and devastating. >> reporter: so, after that mysterious death here, who could anyone trust? dearest friends? >> the word, "betrayal," come to mind? >> oh, absolutely. >> reporter: brothers in arms? >> it's beyond disturbing. >> reporter: closest family? >> she looked at me as if she wished i was dead. >> reporter: maybe no one. >> we were always looking over our shoulder. >> reporter: might still be, had it not been for him. >> pretty shocking stuff. >> i don't think i'll work anything like this again, just because of the -- the different twists and turns. >> reporter: yes, in that toxic swamp of secret identities. of heroes and villains driven by greed and lust and power. >> whoever set this up and

>> reporter: oh, so many lies. >> everything that you were taught as a kid was a lie. >> reporter: this place, where the story begins, seems created not for lies, but for love. the tranquil waters and soft sunsets of bradenton, florida and though the local sheriff's office may seem an unlikely place to find love, here's where it struck a county detective named bob mcclancy. >> got anything to say, bobby? >> i got a lot to say. how many hours do we have left on the tape? >> reporter: a funny man. >> welcome to pasquale's kitchen. >> reporter: and very kind, said his nieces. not just to people. >> we'd be so excited to go over there to see, like, what new animal he got or, you know, like, he would be like, "oh, i got a new bird, come over and see it." >> gimme kiss. >> he had got us little turtles as kids. >> he was a real animal guy,

>> he was, yes. >> reporter: loved his nieces, too. >> he used to take us out on the boat. he just always took care of us. >> reporter: just like he took care of his sister kathy when they were kids. >> it was always like the two of us doing everything, uh-huh. >> causing havoc. >> reporter: as a sheriff's deputy, said his sister kathy, he once faced down a violent gang. >> they had knocked him to the ground and took his gun and everything and beat him up. as a matter of fact, i believe that they fired a shot, but it missed. >> so he barely made it through that one. >> yeah. >> reporter: his marriage couldn't take it. bob mcclancy sought love elsewhere. and then, a southern belle at the sheriff's department, an aloof secretary known as the office whiz caught his eye. her name was martha ann. >> was he crazy about martha ann? >> yes, he was. >> he was really smitten. >> yeah. >> reporter: martha ann had two sons.

>> she was very charming, highly intelligent. >> reporter: sean was adopted as a baby, met jen as a teenager and she became his wife. where sean was from was not discussed at home. but then, he had her. the only mother he'd ever known. >> a mother is the -- the sun and the moon and the stars to a little kid. did it feel like she was? >> i was always told since a young age that the only people you can trust completely are your parents. >> reporter: in the mid 90s, sean's mom martha ann was going through a painful divorce, and then fell for the detective bob. >> bob was very down to earth. and he taught me a lot of things. >> like what? >> how to be a man. how to be a real person. >> sounds like you liked bob. >> i liked bob a lot. >> reporter: in 1995, bob and martha ann got married.

kathy got closer to martha ann. >> we'd go out shopping, that was our big thanksgiving. you know, bobby would stay home and the girls would just take off and go shopping. >> reporter: bob and martha ann retired in the late 90s, left florida and bought a big secluded hillside cabin in coker creek, eastern tennessee, in the shadow of the smoky mountains, not far from where martha ann grew up. place where a man could forget about being a cop and all that violence. by then, sean and jen had their own family and visited from time to time. >> bob especially would -- >> oh yeah. >> -- treat our kids great. >> he was fond of them. he liked them. >> he was the real deal. >> reporter: martha ann went back to work, accounting job. she loved numbers. and they made time for friends, too, like debi hartman. >> we met at church. bob and martha ann just became very dear friends.

found her soul mate. >> she was what i would refer to as the quintessential southern lady. she was like a sister to me. we had the same type of -- of upbringing, the same type of morals. we had fun together. we enjoyed sharing recipes together. she had two boys, i had two girls. we'd talk about our children. we just were very, very close. >> reporter: over the years, they shared cookouts, road trips, church events. >> just like two peas from the same pod. >> reporter: and you could just see, said debi, how much bob and martha ann loved each other. >> never once did i hear them argue or have a sour word against one another, never. just very loving. the perfect couple. >> reporter: and then, may 2006, when martha ann was at work, a family friend stopped by to see bob at home. and, in front of him, well.

>> 911, where is your emergency? >> in coker creek. i can't get a pulse and he appears to be cold to the touch. >> reporter: martha ann got home, then called for her friend debi. >> and she's screaming, and she's like, "bob's dead." and -- and i'm like, "bob's dead?" >> reporter: what- had happened to bob mcclancy? >> i cried for ten hours. i couldn't believe we lost such a great man. >> shocking. >> the two of us just cried our eyes out. the next thing you know, the sheriff comes out. i'm like, "what in the world's going on?" and she's like, "i don't know!"

favorite recliner. the caller, a family friend, said the body was already cold. >> alright, well they're on their way out there, okay? >> thank you, sir. >> reporter: the friend hung up and waited for first responders. >> i was a detective. i'd been a detective for almost a year. >> reporter: detective travis jones of the monroe county sheriff's department was one of the first to go into the house. >> what'd you see when you got there? >> i found robert mcclancy in a recliner. he had a pistol in one hand, and a empty bottle of pills in the other hand. >> have you ever seen such a thing before? >> no. >> reporter: the gun hadn't been fired. but there were pills strewn all over bob mcclancy's body. a white foam around his mouth pointed to an overdose. and a "do not resuscitate" order --signed by bob mcclancy and left in the kitchen said he wanted to die. >> did you see this do not resuscitate order? >> i did. >> reporter: it looked like suicide.

and nieces in florida. >> were just, like, in disbelief. >> it's like a nightmare. >> shocking. >> i can't imagine -- >> when she told me he took an overdose and killed himself. >> do you still remember that moment? >> yes, i do. you know, it --it affected me quite a while. >> reporter: sean too was grief stricken when he heard about his step-dad's death. >> that must come as a shock. >> i think i cried for ten hours driving from florida to tennessee. i couldn't believe we lost such a great man. >> reporter: but shocking as it was to those who knew bob intimately, it was not a complete surprise. why? four letters: ptsd. post traumatic stress disorder. back when the vietnam war was sinking into its bloody depths, bob volunteered to go --as a marine. it took its toll. as did life-threatening

career. bob had been on heavy medications, but still suffered flashbacks, nightmares, depression. martha ann told debi she was very troubled. >> and she said, "i'm trying. but, you know when i'm at work, you know, he'll get in his pills and --she said, "bob is abusing it." >> reporter: bob's sister kathy had also seen warning signs. >> how did you become aware that p.t.s.d. was really beginning to become a factor in his life that had to be dealt with? >> we had been up for thanksgiving, and he had explained to me that right after the holidays that there was a program, and he was going to enter it. >> reporter: bob's new year's resolution for 2006 was to finally beat ptsd. and in january, he set off to nashville for an intensive six-week program run by the va. soon after he got there, he called his sister kathy, with hope in his voice. he'd made a new friend, his roommate

charles kaczmarczyk --went by chuck. >> he had told me that he finally found somebody to talk to that understood what he went through in vietnam, because chuck was there. >> yeah, you kinda need somebody who's been through the same thing i guess. >> yeah, right, yeah. so, he was happy. >> reporter: bob's new veteran friend chuck was no average grunt, he was the very model of a war hero, special forces airman, citations for valor earned in the most daring operations. and such a big shot he was invited to the presidential inauguration. chuck was the sort of tonic bob seemed to need. >> this relationship continued after the program was over, right? >> yes. >> reporter: after they got out of the program in february, bob spent most of his time with chuck -- who lived not far away in knoxville --as they did handyman jobs at each other's homes. >> bob had, you know, kinda replaced everybody else with chuck.

you know, chuck was everything. >> reporter: but bob's ptsd persisted. martha ann did what she could to pick up bob's spirits, though that seemed to backfire when she got a makeover. >> she had had her hair cut short and blonde. >> big change? >> big change. and i'm like, "oh, my god, you look beautiful," and she says, "well, i'm certainly glad you like it." she said, "because bob doesn't like it all. he had a fit that i had -- that i cut my hair off." but i said, "but then, a lotta men like ladies with long hair. so, you know, give him time, he'll come around." >> reporter: when martha ann was at work, chuck kept an eye on bob. >> chuck was right there. >> reporter: but bob was in a downward spiral. martha ann complained that bob was abusing his antidepressants and martha ann and chuck found themselves managing one painful scare after another. in one episode they rushed bob to the va hospital more than three hours away, passed out in the car.

out of it. i understand they had to stop the car because they thought they were gonna have to do cpr on him. >> reporter: bob was stabilized, and after he was deemed well enough -- sent home. >> reporter: two days later on that monday in may, martha ann got up early and went to work as usual, she'd arranged for chuck to check in on bob that afternoon. it was he who found bob, called 911. >> reporter: debi arrived later to find police cars and ambulances and a frantic martha ann. >> and so the two of us just sat there and --and just hugged each other and bawled. and --and you know, just --cried our eyes out. it was horrible. bob was dead. and the next thing you know, the sheriff comes out with chuck -- in a t-shirt and -- and i'm like, "what in the world's going on?"

and she's like, "i don't know." they drove off with --with chuck. >> reporter: police have some questions for chuck. >> to come in, find your friend dead. >> he wasn't rushing around, upset? >> no. he was calm and that was suspicious in itself. >> maybe you got a crime here? >> yes. . want powerful relief. only new alka-seltzer plus free of artificial dyes and preservatives liquid gels delivers the powerful cold symptom relief you need

loudspeaker: clean up, aisle 4. alka-seltzer plus liquid gels. hey, hang in there. thanks. kleenex. someone needs one.

>> reporter: martha ann was a mess. her husband bob dead of an overdose of ptsd medications. and she couldn't even get back into her own house. so her best friend debi and her husband took her in. >> and you know, the three of us just -- you know, "why? what happened?" you know -- crying, you know, all night long, just up all night long, just sobbing and -- and -- and in disbelief that -- that bob was gone. >> to be there for my mom, i left immediately, and drove through the night. >> reporter: and sean was filled with a flood of sorrow and guilt that he hadn't been there for his step-dad bob, as bob had been there for him. >> bob took care of me every day. >> reporter: that'll make you feel close to a person. >> it did.

>> reporter: debi tried, in vain, to ease martha's grief. >> i would bring up, you know, fun things that we had done with bob. >> reporter: you have a cry about it? >> it would be like -- "and now we're not gonna have that anymore." you know, and then -- then i'd start bawling. and, of course, then she'd start bawling with me. >> reporter: and to make it even worse, bob's best friend chuck had been taken away by sheriff's deputies. and so debi watched as martha ann tried to cope with her own sorrow, as she planned her husband's funeral -- anxious at the same time for her friend that those small town cops had the wrong idea about chuck. >> i thought, you know, "okay, this was bob's best buddy now. you know, you're grieving for bob. and you -- now you've gotta take care of chuck." >> reporter: a tough situation for her to be in? >> a tough situation. >> reporter: which was about to get tougher, courtesy of that small town sheriff's deputy, travis jones. something strange here, he thought. he and the other detectives. so they held chuck for

questioning. for one thing, why was he so cool? his best buddy was lying there dead. he wasn't kinda rushing around, and all upset, or anything like that? >> no. >> reporter: calm? >> he was calm, which was kinda suspicious in itself. to come in, find your friend -- dead. and he was calm. >> reporter: as he had been calm and kind of strange on the 911 call. >> mr. mcclancy appears to be, uh, expired. >> reporter: the operator suggested chuck might try to revive bob. >> if you want to try to do some type of cpr on him, i can give you instructions if you want to. >> um, i'm cpr qual -- we do have a do not resuscitate order on him. >> okay. >> reporter: chuck didn't seem to want to save his own best friend. and to the detective that do not resuscitate order seemed maybe just a little too convenient. >> reporter: maybe you got a crime here. >> yes. >> reporter: travis jones wasn't alone. bob's sister kathy had her doubts, too. th

she refused to believe her brother would kill himself. >> i mean, he could have part of his finger hangin' off, he would duct tape it up and -- and keep goin'. you know, so -- >> reporter: that's the kinda guy you saw too? >> yeah. >> reporter: huh. so a pill popping brother didn't make any sense to you -- >> no, it did not. no. >> reporter: suspicions deepened a week later when they traveled to bob's funeral in eastern tennessee. deep in their grief, they met the friend who'd reported bob's death to the police, and who was back in the community as police continued to look into him. his name was chuck kaczmarczyk. how would you describe the guy? >> he was very creepy. there was just something about him, like, when he looked at you, it was almost like he could just stare through you. >> reporter: sean and jen saw the same. >> he seemed like a tough military guy. >> there was a look about him. >> the cold stare. >> yeah.

>> reporter: then kathy got a copy of the 911 call, and what she heard sounded like the verbal equivalent of a thousand yard stare. >> mr. mcclancy appears to be, uh, expired. >> and i played the tape. i played it over and over and wrote it word for word what was in the tape. and it didn't make sense, a couple of things. first he said he didn't touch the body, then he told the 911 operator when he asked about cpr -- he said he didn't need it, he was already gone. well, if you didn't touch the body, how would you know he was gone? >> reporter: how do you go on after that when you're full of these doubts and suspicions? >> you go on. you don't have a choice. you know, but i knew i -- i would not let it drop. >> reporter: but in the end, even though chuck was questioned at length, everything he did put under a microscope, the suspicion appeared to be unfounded. >> the coroner actually ruled it

>> reporter: and then in the weeks and months after bob's death, as suspicions dissipated like the mists in the surrounding hills, chuck could once again walk with his head held high. >> when we did the veteran's parade in knoxville, they put him on the top because he was the most highly decorated. >> reporter: after the awful tragedy of bob's death, chuck got on with his life again, said goodbye to his dear friend, and comforted bob's widow martha ann. oh, boy. >> he's lost his best friend, she's lost her husband. >> reporter: two grieving friends with growing feelings. >> it was like somebody had just dropped a bomb on my head. >> reporter: a cruise ship courtship? >> i looked at her and i said, "are you and chuck together?" .

all these animals as soon as he had passed away. >> reporter: then there were other changes. weeks after bob's death, martha ann invited debi and her husband to celebrate chuck's birthday. dinner at chuck's place. >> and when we got there, martha ann's dining room set was in chuck's dining room. >> reporter: what did you think when you saw that? >> i said, "your furniture's up here?" and she said, "well, it certainly suits his house a whole lot better than mine." >> reporter: but they're just friends? >> they're friends. they're friends. >> reporter: still, how close were they getting? >> i called her one day and i said, "jim and i are going to take a cruise." >> reporter: debi and her husband had gotten an incredible deal from a friend on a week-long caribbean cruise. >> and she said, "well, do you think chuck and i could go on that cruise?" and it was like somebody had just dropped a bomb on my head. >> reporter: "chuck and i?" >> and i said "if there's still spaces available i'm sure she'll

be glad to accommodate you." >> reporter: it turned out there was still space. and martha ann and chuck shared a cabin. >> and so we're on this cruise ship. and every event, you know, they're all dressed matchy, matchy. >> reporter: and now, at mealtimes, when the waiter took orders chuck spoke for martha ann. >> chuck would speak up and say, "the lady will have," and then he would order for her. >> reporter: when guests around the table rolled their eyes, said debi, martha ann stiffened. >> she said, "my mother taught etiquette. and a waiter would never have the nerve to speak to a lady." >> reporter: ooh, my goodness. >> and we were just all speechless. we were like, "hello? do you know what century we're living in?" you heard of women's lib? we're allowed to order for ourselves. i was just absolutely floored

like that. you know, "a waiter would never have the nerve to speak to a lady." >> reporter: wow. >> and i thought, "well, number one, that is not chuck." i mean, he wouldn't know what right fork to use, excuse me. >> reporter: debi at last confronted her good friend and that's when the other shoe dropped. >> and i looked at her. and i said, "are you and chuck together?" and she said, "yeah." and i said, "are you getting married?" and she goes, "oh, heavens no." >> reporter: though she was surprised, debi wanted her good friend to be happy. and when the ship docked in cozumel, mexico, the group disembarked, went shopping, and then returned to the liner and compared their treasures. >> and i said, "so, you know, what did you guys get?" and martha ann's like, "you'll just have to wait and see." very, very mysterious. and you know it was kind of fun.

>> reporter: a few weeks after the cruise and months after bob's death martha ann invited debi and her husband to lunch. >> she said, "i have something to show you." and i said to her, "is this our cozumel surprise?" and she pulls out a ring box that has the most gorgeous wedding set you would ever wanna lay eyes on. it was breathtaking. >> reporter: rings? >> and i'm like, "oh, my god. this is ex, i can't believe this. >> reporter: they weren't getting married immediately, but when that time came, martha ann assured debi, she would play the supporting role. >> and she said, "and i want you to be my maid of honor." and i'm like, "oh, yeah. i'm excited. absolutely. i would love to be and i'm ecstatic for you. and i would be very honored to be your maid of honor." >> reporter: big deal to be asked? >> big deal. >> reporter: so in spite of the apparent sneaking around, thought debi, there was something almost poetic about

and chuck. and maybe dear old bob would approve. >> i'm just so happy that the two of you know, have found one another. you know, i know we've lost somebody dear to us, but something good has come out of this. so congratulations." >> reporter: and, besides romance, there would be so much more to celebrate. martha ann and chuck were going places. they were about to be transformed from local tennessee romantic partners into a sophisticated washington, dc power couple. only in america. >> she met a man from the fbi and she would be travelling on secret missions. >> reporter: flying on air force two or something? >> right, with the vice president. >> reporter: martha ann's secret, sudden change of fortune. .

reporter: it was five months or so after bob's death. late 2006. martha ann and chuck were about to move up in the world. martha ann broke the news to bob's sister kathy. she had parlayed her office-wizardry into a big new high-profile adventure with the federal government, would be spending time in washington, dc.

met a man from the f.b.i., and he offered her a job as a secretary. she was getting a security clearance and she would be traveling out of the country on secret missions. >> reporter: as a secretary? >> yeah. yeah. >> reporter: wasn't long before martha ann was promoted, as she told kathy. she was transferred to the state department. very hush hush. she had a limo at her disposal, two passports and with a government pension would never have any money worries again. her schedule filled up fast. she was apparently moving in the very highest circles. >> reporter: she was already working for or flying on air force two. >> right. yeah, with the vice president yeah. >> reporter: including travel to undisclosed locations. >> reporter: she's kinda hard to get ahold of. >> oh yeah, there was no way of gettin' ahold of her. >> reporter: sean, though he moved to tennessee with jen and the kids, and became a bridge inspector, couldn't reachi

mom either. >> i would call my mom to check in on her, and she would go missing for a month at a time, two months at a time, and you couldn't reach her by cell phone, or home phone. and, as we find out she's out traveling the country. >> reporter: and though she was clearly very busy, martha ann, along with chuck, carved out time to give back to volunteer. >> reporter: together, they traveled around the country, visiting military facilities. >> reporter: they presided over dedications and ceremonies honoring troops and chuck handed flags to war widows at cemeteries. >> chuck would go out with all these medals. and he'd go to the local high school and to veterans parades. >> reporter: he also reconnected with the guys he'd served with way back when, and they recalled old times.

just started his training. he just fit in like all the other guys. he was just one of us. >> he seemed to be a nice guy. >> reporter: bill walter and pj cook are combat veterans who, with chuck, were gunners on some of the most powerful gunships in the us arsenal back in vietnam. >> reporter: then they lost touch. easy to do in such a sprawling military. >> reporter: but, decades later, pj ran into chuck at a reunion of his gunship unit called the spectre association. >> and so it was kinda just good to see the guy. 'cause he was just a guy we served with. i just assumed that he completed his career like i did and i served 22 years and bill served 30 and we gave our whole life to -- to this unit. >> reporter: back in the old days, said bill, chuck's nickname was "kaz." but now? "kaz" had come up in the world from the lowest ranks to the highest. >> so i go up there and i talk to him and i said, "hey, kaz, whatsup, man? how you been doin'?" he says, "oh -- i -- i -- i

"really. wow." and i said, "well, what -- what was your rank?" "i retired as a chief." i'm like, "really." >> reporter: as the former airmen caught up on more than 25 years, chuck flashed his medals. >> and chuck says, "you guys should check your classified records. the va checked my classified records and i found out i got a whole buncha really high medals from my operations in vietnam." >> reporter: chuck invited pj to his home in knoxville, tennessee. >> and, i personally saw these awards on the wall in his house, up in tennessee. >> reporter: what'd you think when you saw 'em? >> oh, i was floored. and i said, "well, that's -- that's really great." he goes, "oh yeah, they finally released these from classification. and here they are." >> reporter: then chuck had an idea. he figured the spectre association could benefit from martha ann's high- wattage political and business savvy. >> "wow, hey, anybody that volunteeo

>> reporter: and as the months went by martha ann carved out time from her schedule to become association secretary. >> she was our recorder. yes. she was really good at taking down notes and making paper and so forth. >> reporter: association members were so impressed with the couple that chuck was promoted to the board. he and martha ann travelled internationally, representing spectre, carrying the unit's mascot. and there was time for fun too. they reveled in their newfound happiness. enjoyed their new responsibilities of course, but also decided to live a little, splash out. >> just outta nowhere they said that, "boy, we certainly like to have an rv." and my wife says, "well, you know, my boss is selling a beautiful rv." well, of course they went and looked at the rv and liked it a lot. so they made him an offer. >> reporter: right next to the rv, chuck noticed a garage'd anniversary edition corvette.

had a mercedes convertible. >> he said, "well, i like corvettes, too. show me that." next thing you know, they bought the corvette too. >> reporter: and pretty soon they were parading their new toys for their old friend debi. >> i hear a knock on the front door. and i open the door. and sitting in front of my house is this gorgeous, like, $350,000 motor home bus. >> reporter: wow. >> and it was to die for. this is what the wealthy of the wealthiest drive. it had been custom made. >> reporter: to debi and others, martha ann and chuck had made it. they'd put bob's painful death behind them and were now a high-powered couple doing good things and living well. sort of success a person wants to share. in early 2008, chuck relished the opportunity to share with a group of young people stories about his many combat exploits.

when he made his speech, there was a reporter in room writing it all down for the local paper. oops. >> she said. "oh, there's more to this story!" >> reporter: new lives that seemed like a dream. but chuck and martha ann were in for a very rude awakening. >> the b.s. alarms are going off in my head like you wouldn't believe. . ly lowers the risk of stroke in people with afib not caused by a heart valve problem. it has similar effectiveness to warfarin. warfarin interferes with vitamin k and at least six blood-clotting factors. xarelto® is selective. targeting one critical factor of your body's natural clotting function.

in the meantime bob's sister kathy had questions for martha ann about chuck, but couldn't reach her what with that state department travel schedule and air force two duties. >> i wanted to give her the benefit of the doubt, but at that time when i told my oldest sister what was going on she said, "oh, there's more to this

story." >> reporter: kathy still wanted answers about her brother's death, but you know how people can start to sound like broken records. >> i think my family, friends, probably everybody was tired of listening to me saying, "this isn't right, i know something had to, you know, had to have happened." >> reporter: when martha ann found the time to respond to kathy, she told her she was imagining things. did she accuse you of meddling? >> yeah, she said, "your brother always said that you always had to get in people's business, you could never just let things let things lie." and i guess that was true. i don't stop till i find out. >> reporter: then, she said. martha ann got even more snippy. >> she literally told me that i needed psychiatric help. i needed to get over the fact that my brother killed himself. and i said, "i will never -- i will never believe that." >> reporter: but kathy wasn't the only one getting the brush off from martha ann. remember

that when she eventually got married, her best friend debi would be maid of honor? at the monthly meeting of the corvette club in knoxville, debi got a surprise when the chairperson asked new members to stand. and -- >> all of a sudden i hear this, "hi, my name's chuck kaczmarczyk and this is my wife, martha ann. and we've bought an anniversary edition corvette." >> reporter: hang on just a second. when he got up at the back of the room that day and said, "i'm chuck and this is my wife," this is the first you knew they were married? >> this is how i found out. >> reporter: you must have been asleep that day when -- >> i -- >> reporter: you were a maid of honor? >> i guess i must have been. so, i said, "chuck, you know, i was -- actually i was kind of hurt." >> reporter: well, i'm not surprised. >> and i said, "you know, when did y'all get married?" "oh, we went on a cruise and we got married on the beach down on some island. and i said, "wow, you know, i'm happy for you. i'm still hurt, but i'm happy for you."

>> reporter: rude awakening. but nothing compared to the morning early in 2008, soon after chuck gave his speech to a group of students eager to hear about his many and heroic combat exploits. and a story about chuck's talk appeared in the newspaper. vets who read it reacted with outrage and at the same time bill walter was hearing about chuck from another veteran's group. >> he was telling all of his war stories to them. and these guys were like, "we never even heard about you before. we've had these reunions for 30-some odd years and this is the first one? your name isn't anywhere on here." >> reporter: special forces guys like bill and pj didn't brag about their service. >> and i'm like, "eh, it's just some guy spouting off. talking trash. trying to impress his buddies." >> reporter: people want to aggrandize their service, right? >> yeah, some guys do. but it's very rare around our people to do that, especially when they're doing it in front of our own people. >> reporter: the veterans called

>> well, chuck went home all mad because they challenged him. "doggonit, they cannot challenge me." >> reporter: no, and chuck sent the group his official military records just to prove he was telling the truth. he also told them due to an emergency he'd be dropping out of circulation for a while wouldn't be able to attend any more reunions anytime soon. >> and the b.s. alarms are going off in my head like you wouldn't believe. >> reporter: bill and others informed the air force. and then the air force contacted the veterans administration. asked them to check this guy out. the job fell to former marine and va investigator in nashville special agent nate landkammer. >> this is definitely the case of a career. i don't think i'll work anything like this again just because of the different twists and turns. >> reporter: twists and turns that would end up leading to a chilling conclusion. and right away, here's what nate heard. >> the people who had served with him were very emphatic that

missions. he specifically talked about the iran hostage rescue, being a part of that being at the fall of saigon and vietnam. >> reporter: he said he was there for all the big stuff? >> yes. >> reporter: naturally, nate's first step was to check chuck's service records. so he went back to the air force and was surprised by what he found in chuck's file. not what he expected. >> his records did contain items substantiating significant combat service in vietnam and after vietnam. >> reporter: did he have a silver star -- >> purple hearts and the distinguished flying cross. some very, very. >> reporter: this is big deal stuff. >> high. very high awards and they were substantiated by names and socials and names of missions and dates that these missions took place. >> reporter: so as far as the air force knew, he was on the up and up? >> yes. >> reporter: but, nate was unsatisfied. something was wrong here. he kept digging.

because down deep where it gets really mucky evil lives and quite possibly evidence of an unimaginable crime. nate landkammer launches a special operation to uncover the truth. >> we started doing surveillance on charles and martha ann. >> chuck in a wheelchair? exactly what were they up to? a crime far darker than anything investigators imagined. >> it just really, really gave you the sense of whoever did this was very evil. .

the combat veterans who knew chuck said he was a fake, which presented a dilemma for the

investigator. but you're sitting in somebody's living room and he's saying to you, "that's all bs?" >> yes. from the air force service members that i talked to that served with him, every one of 'em was emphatic that he did not participate in any combat. >> at all? >> at all. >> reporter: so, nate went back to the airforce and asked them to double check. >> the air force really started poring over these documents and the missions and the order numbers and rather quickly determined that these were all --forged documents. they were not legitimate. >> reporter: yes, chuck had been in the air force. but no acts of heroism. chuck had doctored old mission records, inserting his name and some official- looking stamps, all of it convincing enough that he was able to get the forged documents entered into his own air force record. >> so, he'd gone to an awful lotta trouble to lie about his service? >> yes, he did. >> reporter: and that was no joke to nate --the former marine. >> it's very offensive. very offensive to me. >> personally? >> yes. >> wasn't he --like, appearing at arlington cemer

flags to widows and so on? >> he was appearing at funerals, wearing his purple heart and comforting widows of servicemen who had died in combat. >> reporter: oh but it got worse as nate kept digging, he discovered something about martha ann. martha ann, who'd never donned a military uniform in her life, showed up at a veterans retreat. and claimed that she too had rank and medals and combat experience. she showed off a purple heart. >> several of the attendees at this retreat --specifically remember her talking all about working at the pentagon, being at the pentagon during the 9/11 attacks. and --charles was also telling people that, "yeah, she --she's a full bird colonel in the marine corps, retired." >> and nobody questioned her then? >> no. they --they believed her. >> reporter: but nate discovered that military glory that big

able to feed himself. he wouldn't bathe, he would just be wandering around the house aimlessly. >> guy's in bad shape. >> really bad shape. he should be getting more money from the va than what they're paying him. >> reporter: looked to nate like he'd uncovered a major scam and, if chuck was scamming the va, what was martha ann up to? nate ran her name and what do you know martha ann was getting social security disability payments herself. >> because of? >> she claimed to have back issues where she couldn't walk, she was wheelchair bound. >> reporter: and he found out that while martha ann was entitled to some of her dead husband's benefits, she was claiming a lot more. together -- martha ann and chuck were bilking the government for about $10,000 a month. >> reporter: nate wanted martha ann and chuck -- or charles as his name appeared in the records to be charged with fraud. but first he needed proof they were lying about beingab

>> we started doin' surveillance on -- on charles and martha ann. >> reporter: nate and fellow investigators got into the back of a surveillance van with their video camera -- and they waited. >> we had several agents all participating in -- in surveillance. >> reporter: and it wasn't long before martha ann and chuck appeared outside their home. here they are, supposedly disabled people but by the look of it, perfectly fit. >> we'd observe them doing hours and hours of yard work outside their home. we would -- >> strenuous stuff? >> yes, very strenuous stuff for hours at a time at their knoxville house. watch them pressure washing their driveway and their house and clearing brush. >> reporter: bending over, no sign of back trouble lifting heavy objects. but look at this, here they are arriving at the va for one of chuck's regular assessments. >> you assumed that their demeanor was gonna change anyway.

>> yeah. well, we quickly found out that that was the case. >> reporter: martha ann lifts a heavy wheelchair out of the car. chuck gets in, she wheels him into the va center -- a picture that might wring pity from even the hardest hearts. >> reporter: sometimes when they followed martha ann. >> she was movin' out pretty good, to where you would almost break a sweat tryin' to keep up with her. >> reporter: and when martha ann had her appointments, she and chuck would switch positions. >> it actually got to be kinda humorous. >> reporter: but the couple had only one wheelchair, so nate got to thinking. >> here's how dr. seuss would write it. "and then nate got an idea. a wonderful, devious idea." but it's true, in a way, isn't it? >> yes. >> reporter: what if nate arranged the schedules so that martha ann and chuck had their appointments at the very same time? who would get in the wheelchair then, he wondered?

>> what happened? >> a conniving couple caught in a trap. >> this can't be should you. >> and martha ann's son is about to launch an investigation of his own. . thanks for loading, sweetie. ...oh, baked-on alfredo? ...gotta rinse that. nope. no way. nada. really? dish issues? throw it all in. cascade platinum powers through... your toughest stuck-on food. nice. cascade.

>> reporter: va investigator nate landkammer had set a trap. he knew martha ann and chuck had just one wheelchair as they faked disability, so he set up appointments for them at the social security facility at the same time. >> so they arrived at the facility, and then as we suspected, they only had one wheelchair. so charles, instead of using a wheelchair, he had a walker and a cane. >> a walker and a cane? >> a walker and a cane both. >> reporter: and a knee brace. >> on a stilt leg? >> stilt legged. and then he was toting an oxygen tank as well. >> reporter: as chuck fumbled his way inside, nate and his agents were waiting. busted. >> i interviewed charles. we pulled him into an office. and then martha ann was being questioned by another va oig agent and a social security administration oig agent. >> reporter: martha ann and chuck kaczmarczyk had been found

chuck was no decorated hero, had never once seen combat. no silver stars, no purple hearts. those ribbons, all fake. and martha ann had never walked the hallways of the pentagon as a marine colonel, much less been in the 9/11 attack or flown on air force two. confronted with the evidence, they confessed to perpetuating a complex and massive fraud in fake disability claims. >> had you or your partners in the investigation ever encountered people who were so complexly fraudulent? >> i don't think i'll work a case like this again in my career. >> reporter: but the really sinister stuff was yet to unfold, because family and friends were only just finding out about the fraud. in the summer of 2012, over early morning coffee, martha ann's best friend debi hartman was reading her newspaper. >> and i'm thinking to myself, "this can't be true. this can't

so i start yelling at the top of my lungs, "jim, get up. you've got to come see this." >> reporter: debi's husband jim is a marine veteran. neither he nor debi could believe what they were reading. >> fooled the federal government. stole money from our veterans. >> is it the money that mattered or the -- >> oh, no. it was the fact that they took it out of veteran's pockets that need it. that's -- that just -- sticks in my craw. that hurts. >> it must be quite something to know that this woman, who was your best friend, hid herself from you and -- >> it hurts. >> -- conned you all these years? >> absolutely. took me for a complete sucker. >> reporter: chuck too. >> he would go and -- and present the flags to a widow of a veteran that lost his life. that's -- that's cruel. the people that he took in under

>> reporter: and it wasn't long before sean and jen were reading online, in disbelief about sean's own mother, martha ann, caught in an outrageous fraud with chuck. >> and we found out that they were arrested on eight federal indictments. >> that's how you found out -- >> that is how we found out. we had no idea. >> it made your heart stop. it was heart-wrenching. >> very overwhelming. >> reporter: martha ann stole her dead husband's valor. >> my mom never served a single day in any armed services unit. she assumed bob's purple heart. >> yeah, she did. >> and told these veterans groups that that was her purple heart that she received in the 9/11 pentagon attack. >> reporter: by early 2013, martha ann and chuck were sentenced. >> charles got 30 months federal and then martha ann got 20. >> reporter: they'd spent most of their ill-gotten gains, of course. so, before she began her prison sentence, martha ann prepared to

sell the house for restitution. >> she started, you know, boxing up all of her belongings and selling things and closing up the house. >> reporter: but martha ann was a notorious packrat. she had kept everything. trunks full of clothes, thousands of pages of receipts, contracts, documents. so what did she do? she gave them to her son sean and his wife jen for safekeeping. >> if she asks me to do something, i will do it. >> well, and in a way i suppose if she gave things to you, then the feds or the other investigative agencies maybe wouldn't have access to them. >> well, yes. >> right. >> reporter: but when those boxes of records arrived, sean and jen dived in ravenously to see what they could uncover. >> who keeps all those documents? >> 30,000. >> 30,000 documents. that must have been some job going through all of this stuff, huh? >> it was overwhelming. it was.

>> i did feel conflicted about digging into my mom's affairs, but i had to know the truth. >> reporter: then sean turned on one of the computers his mom had sent for safekeeping. he intended their kids to use it, so he wanted to be sure it was clean. he checked the trash bin and couldn't believe what he saw. >> and there were photos of my stepdad bob, deceased. >> dead. >> dead. there were many photos in there. >> reporter: they were photos of bob mcclancy, lying dead in his recliner in 2006. >> what was it like to see those pictures? >> disturbing. >> reporter: here were pictures that told an entirely different story to what sean and jen knew. >> in one picture, bob would have a pistol in one hand and a bottle of pills in the other. in another picture, bob would just have a bottle of pills and nothing in the other hand. >> and it was odd the way he was

the way his leg was placed looking back at that i think you could tell that was body manipulation. >> reporter: the pictures didn't appear to be police photos because they were all apparently taken before any police arrived on the scene. >> so you called the cops. >> right away. >> reporter: sean, conflicted, was suddenly faced with the prospect he may be implicating his own mom. and, so, torn, he called nate the va investigator, and began to tell him all about bob mcclancy's death in 2006. >> he said i just want to talk to you guys about this and get it off my chest 'cause it's really been bothering me. and if there's nothing to it, great. but if there is, i think it needs to be investigated. >> it's like pulling a string, isn't it? >> yes. >> reporter: and now the string led back in time, six years back to that dismal afternoon in the tennessee hills, when chuck called 911 to report a suicide. >> it was just part of a very complex, evil scheme. you knowth

that i got when i first saw the photographs. >> reporter: so maybe this wasn't after all just a fraud case. maybe he thought someone had gotten away with murder. >> did you suspect he had killed his friend bob? >> that was a possibility. >> reporter: old suspicions. what had happened to the case against chuck all those years ago? >> it was devastating. i felt guilty about it. >> like you'd blown it? >> yes. . a different kind of medicine for moderate to severe plaque psoriasis. proven to help the majority of people find clear or almost clear skin. 8 out of 10 people saw 75% skin clearance at 3 months. while the majority saw 90% clearance.

>> reporter: va special agent nate landkammer had martha ann mcclancy and chuck kaczmarczyk for fraud. but his investigation was about to take a sudden turn to evil. he had learned about the suspicious photos sean and jen found in the computer martha ann had given them pictures of bob lying dead. >> sean contacted the u.s. attorney and said, "i have some information that you might want to know that may be helpful to the investigation." >> there were a lot of phone conversations between send

nate and nate and i. >> reporter: nate learned there had been an investigation into bob mcclancy's death six years earlier in 2006. remember, detective travis jones had been called to the house after a 911 call placed by chuck. >> i just walked into the residence. it's the mcclancy residence. mr. mcclancy appears to be expired. back then, the detective thought chuck was acting way too calm, was avoiding cpr on his best friend, and was staging that perhaps too convenient "do not resuscitate" order. and it turned out the detective had good reason to want to question chuck after he discovered a digital camera inside a backpack. >> reporter: who found the camera? >> i did. >> reporter: did you, like, assume anything about its ownership? >> no, i just assumed it belonged to the residents there, mr. mcclancy. >> reporter: did you think as you were opening it up, "hey, wait a minute. maybe i shouldn't be doing this?"

standard practice. >> reporter: on the assumption that what, that there's no need to get a search warrant for a dead guy's camera? >> right. >> reporter: on the camera were pictures of the deceased bob mcclancy his body positioned differently than the way the police found him. they were the same pictures sean would later find on the computer some showing bob mcclancy holding a revolver, others the revolver and the pill bottle. what did you think when you saw that? >> that we had a staged scene for sure. >> reporter: maybe a staged scene. maybe you got a crime here. >> yes. >> reporter: that's when the detective decided to question chuck. >> we took him down to the sheriff's office. >> reporter: at the sheriff's office, confronted with the photo evidence, chuck's story changed dramatically. his first statement to the police had been he arrived at the house after bob died and called 911. now he was telling them that

when he arrived, bob wasn't quite dead, but was taking his last gasps. >> he had come home, found mr. mcclancy, said he was still alive and he was barely breathing. >> reporter: chuck said he was the one who staged the scene and took the photos because, he didn't know bob was going to die. and hoped that photos of his friend suffering might help bob leverage more benefits from the va. did you suspect that he killed his friend bob? >> that was a possibility. >> reporter: at the time, detective jones believed he had at least a case of negligence. >> his negligence caused his death. that was the evidence we had at the time. >> reporter: if he had moved quicker, or called 911 sooner, or tried to do cpr, or something his friend would still be alive? >> he let him die before he called 911. >> reporter: chuck was charged with tampering with evidence and criminal negligence. so it must have seemed like you kind of had him on that. >> that's w

>> reporter: but that's not what happened. before the case could go to trial, a judge ruled the photos taken by chuck were not admissible in a court of law. why? the camera belonged to chuck not bob and detective jones had gathered the photos without a search warrant. in the courtroom that was it. the case against chuck kaczmarczyk collapsed. go back to that time when you got that ruling, and it was basically thrown out, and you weren't going to get the case at all. what was that like for you? >> it was devastating. >> reporter: do you feel -- did you feel as if you were responsible -- >> i did. i felt guilty about it. >> reporter: like you'd blown it? >> yes. >> reporter: six years later, in 2012, chuck was a convicted conman and investigator nate landkammer was looking at the very same images on the computer. >> i knew that the local sheriff's department had some suspicions that chuck had done something, but really weren't

through, you know, charges being able to stick. >> but to nate, maybe chuck was up to his lying eyeballs in bob mcclancy's death. >> it just really, really gave you the sense of, you know, whoever set this up and whoever did this and whoever took these pictures was very evil. >> reporter: chuck had taken the pictures, but what were they doing on the computer sean got from his mother martha ann? then nate and the state investigators who'd joined him, came up with a plan. they'd put sean and jen on the spot. they'd get sean to spy on his mom. sean was about to become an undercover agent. what's it like to phone your mother knowing that you're going to be putting her on tape. >> it had to be done. i asked her why the pictures were there. >> and she said, "pictures of bob?"

reporter: it should be noted that sean's relationship with his mother, martha ann, was never particularly warm. martha ann wasn't exactly the cuddly, protective type. >> i think i was more scared of

>> reporter: remember, sean had been adopted as an infant by martha ann and her first husband in florida. he said his mom was strict and quick to punish if sean crossed her red lines. >> you knew that was it. your life was not going to be as pleasant for a period of time. >> reporter: what did you think when you saw her treating sean that way? >> it made me angry. >> reporter: even so, sean tried to stay loyal to his mom. but now he was about to go against her in a way he never could have imagined. he'd seen the photos of bob's dead body, contacted the investigator nate landkammer, and now he and jen were turning up more evidence for nate's investigation. >> we were coming across all of these what we would call crazy, crazy documents. we couldn't wrap our brain around 'em. >> reporter: and one of those mind-boggling documents was bob mcclancy's will.

>> reporter: bob had been married before he met martha ann and had a daughter. the daughter hadn't seen bob in years and she was cut out of bob's will. >> he wanted nothing to do with her and, "i don't want you to know about -- i don't want you to know about my death." and, "i'm leaving you $1 of -- of my estate. >> reporter: the wording seemed especially harsh. >> i didn't know bob mcclancy. most fathers would not write something this cruel to their only daughter. i just realized that this is just not adding up. and it just was very, very suspicious. >> reporter: bob's sister kathy thought it was fishy, too. >> i knew this wasn't bobby's will. i even said that to my daughters, "uncle bobby would have never put this in here." >> no. >> never. >> reporter: nate concluded that martha ann, the sole beneficiary, had forged the will. >> reporter: came from martha ann, not from -- >> came from -- >> reporter: not from bob. >> came from martha ann. and the will in particular ended up being a major part of the investigation.

discovered a curious date, or dates, martha ann's wedding to chuck. >> if you wait until after you turn 57 and remarry then, you can keep the benefits for the rest of your life. and she ended up marrying chuck in las vegas, nevada one day after her fifty- seventh birthday, which allowed her to keep the -- the va benefits associated with bob for the rest of her life. >> reporter: martha ann used the same formula to claim her husband's social security disability benefits. >> there was a stipulation under her social security benefits that she could not remarry prior to her sixtieth birthday. so, of course -- >> reporter: a little dancing had to be done there. >> yeah. so, they then got married again three years to the date after their first marriage. so yeah, they had essentially two marriage dates. >> reporter: with so much compelling evidence against martha ann and chuck, nate figured it was more than a coincidence that martha ann had

known to be with her husband bob. >> reporter: if chuck had murdered bob, then martha ann who'd married chuck just five months after bob's death must have known something. >> we really never believed that she could be capable of killing bob. >> reporter: just who would do such a thing, right? >> well, and we knew that chuck was the last person with bob. so we really didn't think martha was the one that had killed bob. i think we both believed that it was chuck. >> reporter: but they wanted to be sure. if there was a murder conspiracy maybe a son could find out from his mother. they decided to recruit sean, get him to wear a wire and place a call to his mom martha ann and ask her what she knew about the photos. sean agreed. >> so he was willin' to make the phone call. and we gave him a, you know, recording device. >> reporter: what's it like to

you're going to be putting her on the spot that way on tape with somebody listening? >> well, it had to be done. >> reporter: you nervous? >> i was nervous. but at the same time -- >> reporter: you gotta know. you have to know. >> reporter: nate and sean's wife jen were listening as the call began. >> we talked for about 45 minutes to an hour. he was, like, "hey, mom. the kids were on the computer over the weekend and when i got in the trash, i found, like, over 100 photographs in there of bob dead." >> i asked her why the pictures were there. >> and she said, "photos of bob?" >> she started saying, i think those are police photos, sean. and he was, like, "mom, these photographs are not police photos. >> and then he said he has a pill bottle and a pistol and then he doesn't. and he's -- he's dead. why are these pictures in here? >> her spontaneous reaction to this being posed to her was, "for god's sake, sean, delete those photographs," you kn

>> reporter: it was a cold night, december, 2012. va special agent nate landkammer waited outside a jail cell in tennessee, nervous, uncertain. inside, investigators were trying to persuade chuck kazcmarczk to reveal, finally, the real story of that deadly monday in 2006. who did what and why. and then, out came the investigators, smiles on their faces.

>> that was kind of like the culmination of everything, knowing that what we had suspected was correct. >> reporter: nate understood full well, the stage was set for an epic he said/she said battle between two major-league con artists. he couldn't know whose story would win. but nate was pretty sure the one finally telling the truth was chuck. >> we didn't suspect it anymore, now we know. >> reporter: in november of 2015, in madisonville, tennessee, martha ann mcclancy went on trial. >> she was charged with first degree premeditated murder and conspiracy to commit first degree murder. >> reporter: attorney matthew rogers was appointed to defend martha ann, accused of poisoning bob with his ptsd medications and conspiring with her lover, chuck, to make bob's death look like a suicide, and then stealing bob's assets and benefits.

could mean the death penalty. but martha ann was fully ready to defend herself with an absolute blanket denial. >> she maintained her innocence from the very beginning. >> she made it very clear that she wanted to speak with the jury and tell her side of the story. >> reporter: there were no cameras in the courtroom, but microphones were allowed. >> bob was the love of my life. i, i couldn't have imagined losing him, and i didn't want to lose him. i didn't want to be without him. >> reporter: and besides, she testified, she didn't need to kill her husband. >> there's these allegations that you and chuck were in this for some sort of financial reason or something, too. what do you say about that? >> no, sir, absolutely not. i --i had my own money. i had my own funds. >> to this day would you be better off had bob mcclancy remained alive? >> oh, absolutely. >> martha ann did not benefit from the death of bob mcclancy.

through the government for his military service whether he had remained alive or whether he had passed. >> reporter: chuck was the villain, said attorney rogers. chuck played martha ann like a fiddle. >> mrs. mcclancy was snowed by mr. kaczymarczyk's cons and -- and manipulations, just as the government had been on numerous occasions in the past. mrs. mcclancy was another victim of mr. kaczymarczyk. >> he had never, ever indicated to me in any way that he had lied about what he had done in the military, about what he had received. um, i thought that he had all these awards. >> reporter: lying chuck, said attorney rogers, would say anything to avoid the blame. >> what did chuck not lie about? he's a habitual liar and that's proven and documented. i -- i was in a position to attack his credibility, and that wasn't very hard. >> reporter: it was chuck who forged bob's will, sd

ann. and she went along with it only because the content of the will was what bob wanted. >> and that was initially chuck's idea? >> it was chuck's idea and he did it. >> and you acknowledge today that you went along with that. >> i, i did go along with it. >> reporter: she had no idea, she said, that chuck was planning to take those awful pictures. and when questioned about the flashy government job she'd told bob's sister kathy about in washington, d.c., martha ann simply scoffed that it was a joke. >> i mean, it was just a hoax. that's all in the world it was, was a hoax to more or less get her to stop bugging me. >> attorney rogers took martha ann back to the day bob died. a normal day, she said. >> you went to work that day? >> yes, sir, i went to work that day. >> reporter: and she didn't have a clue that anything was wrong, she testified, until she arrived

home after 6:00 p.m. >> a young detective came out and took hold of my hands and he said, "this is going to be the most difficult thing that you ever hear." and he said, "your husband has passed away." >> reporter: conspiracy with chuck? of course not, she said. >> did you and chuck ever have a conversation about getting rid of your husband? >> no, no, we did not. i don't know where he has come up with this. >> reporter: first time she heard about a murder conspiracy, she said, was after she told chuck she wanted to divorce him in 2012. >> i didn't know about it until much later on, when this wild concocted story of my having murdered my husband was told for the first time, and it was told by chuck kaczmarczyk. >> did you kill your husband? >> no, sir, i did not. i did not kill bob mcclancy. i did not have anything to do with killing bob mcclancy. i ot

than what i know, that he died of a drug overdose. >> reporter: and that was martha ann's story. every word of it was true, she swore. >> if martha ann believes that her husband, bob mcclancy, was murdered, she would say that it was chuck kaczymarczyk. he was there with bob mcclancy when he died, by admission. he was the one that supposedly found him dead. he was the one that took photographs of mr. mcclancy and manipulated the scene of the death, whether it was a crime scene or not. >> reporter: but, the battle of the con artists was just getting started. and the prosecutors believed they had a strong case. >> what was the most important piece of evidence in your view? >> the most important piece of evidence, of course, was the mirandized confession taken from chuck kaczmarczyk. >> reporter: and what a dark and devious story of murder chuck was about to tell. >> make it look as natural as

the years of fraud, the money and position and good will stolen from honest veterans were only background now. martha ann mcclancy charged with premeditated first degree murder, faced the death penalty. >> a lot of work went into this case 12,000 pages of documents. >> reporter: assistant district attorneys cindy schemel and mac mccoin took on the hugely difficult task of boiling down a story every bit as convoluted as it was devious.

>> and to be able to tell it in such a simple story so 12 people off the street understand it -- >> that's really complicated to do. >> that's the hard thing. >> reporter: they would prosecute what was clearly a complex case using a well-tested strategy. >> the old kiss method. >> kiss? >> keep it simple stupid. >> reporter: they presented evidence of bob mcclancy's forged will and the wedding dates but not chuck's photos which had collapsed the case in 2006. instead, they showed the jury police photos while sean described the photos he found. all as he faced his own mother. >> she looked at me as if she wished i was dead. she looked at me with the most hate i've ever seen from anyone -- >> reporter: when bob's sister kathy testified. >> i wanted to jump over the bench and choke her, but i thought, "well, thaton

me anyplace," but she just sat there. she showed no emotion, just cold. coldhearted person. >> reporter: at last, martha ann's fate rested in the hands of the state's star witness her lying husband, chuck, now on the stand. >> reporter: chuck began at the beginning, when he met bob at that ptsd clinic in 2006. >> did he ever express any suicidal thoughts to you? >> no. >> reporter: then bob introduced him to martha ann, said chuck, they began an affair and she began scheming to do away with bob. >> she had mentioned on several occasions that she'd like to get rid of him and if he went away that we could be together. >> reporter: she made all the decisions, said chuck. investigator nate landakmmer agreed. >> the investigation clearly showed that she was the mastermind. >> and who was in charge of his medication? >> martha.

>> turns out, before he died, that martha ann was put in charge of all of his meds. that bob was not to have any access to his own medications whatsoever -- >> wow. >> reporter: for days before bob died, said chuck, martha ann ground up the pills into something she called magic dust. >> she had fixed his favorite meal for him and then afterwards remarked that she had used magic dust on him. >> reporter: the doses got bigger, and bob more disoriented. it was martha ann's idea, said chuck, to rush bob to the va hospital suffering apparent overdoses to reinforce the impression that bob was suicidal. >> reporter: and then two days after his last trip to the va hospital -- >> i was pretty sure that she was going to give him a lethal dose of the drugs because she was so specific about me being there at a certain period of the day on that date. >> she told him specifically, "i'm gonna load him up with some

leave for work. she said, "you come over. and find him. he should be dead by then. i'll be at work. i'll have an alibi." >> that if i found him dead, just to make it simple, keep it simple --to make it look as natural as possible or to make it look like a suicide. >> reporter: then, chuck confessed, he staged the scene. >> i um took some photos. there was also um a bottle of pills that i put in his hand and also a gun. >> reporter: those photos? intended as leverage to try to squeeze more money out of the va. and the gun? chuck claimed it was to honor the wishes of a former detective to die with a gun in his hand. >> you thought that was an honorable thing to do for bob while you were killing him and sleeping with his wife? >> i wasn't killing him. >> you weren't killing him, while you were letting him be killed and sleeping with his wife? >> yes. >> i think they were evil, but i think the root of their evil was their greed.

>> reporter: there it was. martha ann poisoned bob and chuck was her willing servant. >> a match made in hell --quite frankly. >> reporter: the motive: chuck and martha ann wanted to be together and they wanted money. >> how much money all together? >> i'd say close to a $1 million. >> close to a $1 million. >> reporter: the prosecution rested with a scathing indictment of martha ann. >> to have your husband die in stages thinking he's -- losing his mind because you keep overdosing him with these drugs until you get that to fatal dose, it's hard to comprehend how some people can be that evil. >> reporter: but how would the jury judge martha ann? >> the jury was out for quite a while, wasn't it? >> yes. it-- scared us badly. we didn't know whether we'd won or lost. >> reporter: sean and debi and kathy were all in court, nervous hearts racing. >> i waited ten years. i was just trying to hold myself together, you know?

>> reporter: and then it came. >> we, the jury, find the defendant, martha ann mcclancy a.k.a. martha ann kaczmarczyk, not guilty of the offense of first degree murder. >> reporter: not guilty! a wave of disappointment washed through the room. >> i wish she would've gotten the death penalty. >> both her and chuck. >> reporter: but the jury wasn't finished. >> we, the jury -- >> reporter: martha ann was found guilty of attempted murder and conspiracy to commit murder. >> it wasn't really a happy feeling. i'm glad justice was served, but i still thought, "why did you have to kill him?" >> do you think they got it right, that she was the one primarily responsible? >> yes, she was a real conniver, yeah. >> reporter: chuck had already made his deal, he'd already pleaded guilty to murder conspiracy and got 25 years in prison. >> does chuck's sentence make sense to you? >> he did conspire and assis

her in this. he was necessary to be able to prove the case against her. so when you look at that, it makes sense. >> reporter: in june 2016, when it was martha ann's turn to receive her sentence she clung to a walker. faking disability again? that's what the prosecutors believed. and then the judge tore into her. >> the slow poisoning and slipping of life from an individual is exceptionally heinous. >> reporter: he gave her the maximum and aged 67 she got 50 years in prison. and that's where she is now. >> i'm a firm believer that karma will get you. and i think it's got her. >> reporter: ex-best friend debi, was relieved. >> absolutely the epitome of evil. she was the meanest, cruelest and she didn't get away with it. and that made me feel a little

>> reporter: and for the detective who believed nearly ten years earlier that chuck was guilty -- it was vindication. >> the fact of the matter is if you had not looked at that camera, if you had not opened up those photographs. >> we wouldn't be sittin' here talkin' today. >> no. and justice woulda never got served for the mcclancy family. >> so it came out all right after all. >> it did. took a while, but it did. >> reporter: yes it did. no small thanks to martha ann's son. sean. >> no child should ever have to testify against their parent. >> that was the hardest thing you ever did. >> that was the hardest thing. >> reporter: and he hasn't been the same since finding out about his mom's monstrous crimes. >> i think he had a lot of trouble wrapping his head around it and believing that she was capable of this. bob was a man of right. he was a detective, he was a marine. and he would fight for justice

and there was no way that he was gonna go down like that and be silenced that way. >> reporter: but there is one more piece of unfinished business. sean, remember, was adopted -- >> i had always been told that i would never find out where i was actually from or who my birth parents would be. >> reporter: but even after a florida court denied him access to his adoption records, he was determined to find his birth parents. then he got in touch with ancestry dna, and what do you know? >> we hit the bullseye immediately. >> reporter: they found his birth father, living in maine. >> it feels amazing. overwhelming. >> reporter: now sean is making plans to meet him, both excited and nervous.

as he searches for his birth mother, sean has a whole new life to discover. a life all his own. .
