the outdoor living space. from the outdoor kitchen and bar, with handcrafted spanish tiles, to the fire pit lounge, and of course, what house in california would be complete without a pool? trust me when i tell you, this entire outdoor space rocks, both day and night. thanks so much for joining me today on this tour of tyra banks' very welcoming home. i hope you've enjoyed this closeup look at the spanish colonial revival home. ms. banks is the host and executive producer of the long running tv show america's next top model. she also hosts a new talk show called fab life. up next, we check out charleston, south carolina's oldest home.

welcome back to "open house." now we head down to charleston, south carolina to tour what is widely considered to be it's oldest home. it was built in 1712, and has seen the entire city grow around it. and, come to think of it, the entire nation. it's filled with gorgeous intricate detail, and is one of the original examples that distinguishes charleston style architecture. and with one of the largest private gardens in the city,

it is a true urban retreat. check this out. hello. i'm andrew drury of carolina one real estate. welcome to charleston. i'm excited to show you one of the most significant houses in the entire city. so follow me. come on! this georgian style home was built in 1712, 20 years before the birth of george washington. there's even the original carriage stone and the two hitching posts. it's known as the colonel william rhett house, after its builder and original owner. the property is a half an acre, including the main house and two carriage houses. let's take a look at the main house. one of the distinguishing characteristics of charleston homes are its piazzas, to catch the sea breeze. right here, you'll notice something very charleston. these are called jalousies. they were part of the entrance of piazzas to provide privacy. another distinguishing charleston characteristic is this joggling board. in the old days, a woman would sit on one side.

a man would sit on the other. and they'd bounce until they met in the middle. this home is on the national register of historic places, and its georgian features greet you, the moment you walk in, characteristics like the carpenter lock, this mahogany banister. another interesting feature is this newel post and the mortgage button. the folklore was that you'd receive this button after you paid your mortgage off, and you would put it on top of your newel post, to let everyone know that your home was debt free. follow me into the living room. this is the largest room in the house. and it's a great place to entertain. or just put your feet up with a good book by the fireplace. 12 foot high ceilings, with intricate dental molding, and wainscotings around the room. and this is a grand living room, where you'd do most of your entertaining. for more intimate gathering, follow me. we call this the silver room, because of its ornate silver wallpaper.

originally, when the house was constructed, this was considered the receiving room, where you greet your guests. today, it's an intimate nook, perfect for sitting by the fire with a glass of wine or a cup of coffee. there's a hidden bar behind this door, and even a hidden elevator. this beautiful dining room is most decorative room in the house. just look at this gorgeous rococo plasterwork. it was installed by the original owner's daughter in 1745. and it's the earliest example of rococo plaster work in the country. this room is also interesting because of the pieces of furniture in it. this table has seated generals and governors, and the charles lamier pair table is one of two. its twin is in the white house. and if the dinner conversation happens to get a little boring, just turn on a little music over here. what would you like to hear? this music box is the original ipod. [music playing] it's pieces like this that add a touch of whimsy to this formal dining room.

when the weather's this nice, we spend a lot of time outdoors. and looking around, it's easy to see why. spread out over half an acre are five separate garden rooms, each with their own purpose, designed by world renowned landscape architect umberto innocenti. the overall effect is organization, tranquility, and of course, beauty. the first room was designed for herbs and medicine. the center room is perfect for outdoor parties, and can easily handle 300 people. and they elliptical curve in the bar terre is perfect for a band. we call this the oak forest. it leads to the formal garden. and this is known as the garden of the four seasons. out here, you feel like you're in your own private park. so there you have it. i hope you enjoyed taking a look around with me. just remember, whether you're here for a generation or a century, this gracious historic property in charleston will always welcome you home. thanks for stopping by.

sara gore: coming up next on "open house," we are touring a grand home in connecticut. we'll be right back.

welcome back. our next stop today is an exclusive gated community in connecticut. we are touring a grand georgian style home with elegant details throughout. also, it's not often you find a house with its own observatory and ice rink. check this out. good morning. i'm rick ayre. i'm the estate manager at 21 hurlingham drive in backcountry greenwich on conyers farm. i can't wait to show you around this beautiful home.

this 13,000 square foot home is this incredible 1985 brick georgian. eight bedrooms, eight bathrooms, and is incredible for entertaining. the lower level is home to an elegant wine cellar, and a home theater. and through the french doors, it opens up to the pool. the house sits on 13 acres, and it has anything you could ever wish for, and more. you've got your pool, pool house, formal gardens, and green house, observatory, and one more surprise right this way. down here, you have your very own private ice rink. and in the summer, it converts back to a tennis court. it's just one more feature of opulence on this already magical estate. thank you for joining me today for this glimpse of the very

best of backcountry greenwich. still sara gore: ahead on "open house," anna burke shares her inspiring design secrets. we'll be right back.

we are wrapping things up today with young, up and coming interior designer, anna burke. anna is known for making home looks collected, not decorated. take a look at how anna incorporated her clean and classic sensibility in her client's home. hi, i'm interior designer anna burke. today, i'm going to be taking you on a tour of one of my favorite projects on the upper east side, a manhattan house. my design aesthetic is clean and classic. i like to create spaces that feel lived in and collected, not overly decorated. design, for me, is not just about making the home look beautiful. it's about making people look beautiful within the home. and one of the simplest ways to do that is through lighting. in this home, i use light at all different levels.

lamps on console tables, wall sconces, as well as overhead fixtures, to create a warm, soft glow. it really makes people look their best. in the living area, i used soft, neutral upholstery to create a backdrop for fun and wild pillows. when it comes to pillows, i love mixing different patterns and textures. another way that i define the spaces in this apartment was through the use of area rugs. this home has absolutely gorgeous floors, so i sought to use rugs that were neutral but soft underfoot. one of the reasons i like this coffee table is it doesn't have a glass top. i think for people who have kids, glass top coffee tables are always dirty. the coffee table also serves as a great clean contrast to the more ornate rope chairs, which are two of my favorite pieces in the apartment. my favorite piece in the dining area is this massive gold iron pendant light. it creates an incredible cascading pattern on the ceiling, especially at night. this light was a bit of a risk for the client, and for me, too, because of its large size.

but once it went up, we knew it was the perfect piece for the room. i used antique french dining chairs with a more modern bronze tulip based dining table. i love using antiques with more contemporary pieces. for me, dining spaces in the city should feel funky, casual, and modern. a place where you can feed your kids, and also host an elegant dinner party. we lacquered the library a bright cornflower blue. it's the biggest pop of color in the apartment, and i love the way that it reads off of the living room. i think every room needs one strong color, or as i like to call them, shock colors. in this room, this deep shade of magenta was the perfect shade. libraries don't have to be stuffy. they can be a cozy place where you can display family photos, books you've collected over the years, and still use funky textiles and prints. thanks for coming on a tour with me of this fun yet sophisticated family home. i hope it inspires you to create a space that's true to your own personality.

that's all for now. we hope you enjoyed the show. to see any of these amazing homes again, head to openhousetv.com, and connect with us, @openhousetv. before you go, i want to remind you about our newest weekend tradition. check out my breakfast with "open house" videos on facebook every weekend morning, and be sure to share what you are having with us. join "open house" for breakfast. thanks for watching, and we'll see you next week.

i never dreamed somebody could do this. i didn't know why anybody would want to kill him. you watch it on tv. you see it all the time. you just don't think it can happen to you. >> they were a young couple in a hurry to make their fortune. >> 50's, 100's, 20's. piles of money. >> building a life. until one life ended. all too soon. >> what happened to your husband, ma'am? >> i believe he's -- he's dead. he was laying on the floor, and i got scared, and i ran out of the house. >> a young father murdered in broad daylight.

didn't look like a robbery. lots of valuables left behind. lots of secrets too. >> it just kind of sent chills up my back. >> something was tearing a family apart. >> i don't even know where to start. >> or was it -- someone? >> the most cold-blooded, evil person. >> a family feud, and an innocent man, caught in the middle. >> you know these shows you watch that people see the ghosts of their loved ones? i wanted that so bad, so bad. >> i'm lester holt, and this is "dateline." here's keith morrison with "the root of all evil." ♪ reporter: the hunting is good here in the arkansas delta. twice a year, a horde of migrating mallards descends on flooded rice fields. deer stare out through thickets of hardwood. you have to be quiet, sure-footed, your aim true.

that's what marc despain's dad taught him. that's what marc taught his own son. before hatred wormed its way in. sometimes it's overwhelming that anger, isn't it? >> it is. it is. >> reporter: the anger that pitted father against son. >> it almost got physical. it just -- it breaks my heart. >> reporter: and husband against wife. >> i just wanted to go into protective mode and protect us all. >> reporter: and brought the hunting to town on a deathly quiet summer afternoon. >> can you please hurry? >> okay. i'm going to get them out there. >> please send an ambulance. >> reporter: what could be left but the bitter taste of recrimination. >> he is evil. he is not the kind person that he's got the public convinced that he is. >> reporter: jonesboro is both a college town and a farm town.

tends to the needs of young minds and rice farmers on the vast plain of sticky, fertile clay west of the mississippi river. it's where marc despain breezed through school with his easy charm. tana is his mother. >> he was the only freshman that we know of that was chosen by a senior to go to the senior prom. >> reporter: marc became a high school football star and his sister jacque watched him bring his trophies home to lay at the feet of his father, jack. >> he really did look up to dad. and he -- you know, he always wanted to, you know, impress him and stuff. >> reporter: and then -- well, its an old story, really. >> when i was 18 and he was 19, we just bumped into each other. >> reporter: pretty michelle. she was sitting on top of a car when marc spotted her one night. tiny, doe-eyed, and, before long, pregnant. >> the way i was brought up, you

know, if you got a girl pregnant, you married her. that's just -- that was just what you did. >> reporter: so there was a shotgun wedding. two families thrown together, marc and his parents, jack and tana. michelle and her long divorced parents, her mom kathy and her dad carl. michelle also brought along a baby from an earlier relationship. >> and he never treated her like she was not his. never. >> reporter: together they had two boys. >> he loved his kids. i mean, just anything they ever dreamed of, he would do his damndest to get it. anything. >> reporter: the little family moved into a trailer marc's parents bought them. and marc studied hard to become a real estate appraiser, like his mom, and went into business with his parents, which, said michelle, is about when things began to go wrong. >> marc didn't like to be pushed around by his dad.

he was an independent person. >> reporter: the growing tension spilled over at the kitchen table. marc demanded a bigger share of the money. they argued. and then michelle chimed in. oh boy. >> oh my goodness, when she opened her mouth, dad just flipped off the handle. and, of course, marc just, i don't know, stepped in as a husband, like a husband should do. >> reporter: that's how it began, the trouble between father and son. the trouble that was going to get so much worse. marc split away from the family business. michelle helped with the book-keeping. >> i was just amazed at what they were able to accomplish. >> reporter: and they were a good team, said michelle's mom, kathy. >> they both just had the ability to work together to -- and make money. >> reporter: marc got into real estate investment. his first, a trailer park no one else would touch.

>> i couldn't believe he bought that. i was just, what are you thinking? have you lost your mind? he flipped it. made him about $100,000 profit. >> reporter: and so having done it once, he figured he'd do it again. >> absolutely. >> reporter: and again and again. >> absolutely. >> reporter: and the money seemed to roll in. marc moved his family to an upscale neighborhood in the southern part of town. adrift from his own parents, he spent more and more time with michelle's, taking them on family trips. even hired michelle's dad, carl, to be his rent collector. >> i remember a lot of times walking in and carl would be sitting at the dining room table. and must be 50's, 100's, 20's. he was counting them like a drug dealer. >> reporter: just piles of money? >> piles of money. >> reporter: and then, one august afternoon, michelle came home from work early. >> when i walked in, there weren't any lights on. everything was knocked onto the floor. >> reporter: and then she got to the kitchen. and there he was. >> and he's laying in the floor,

and there was blood coming all out from behind him. and i shook his leg and said his name. and i looked around, and there was stuff in the floor everywhere. and i got scared. >> reporter: she ran outside, terrified, and called 911. >> 911, what's your emergency? >> my -- my -- my husband. i just came home -- >> ma'am, i need you to take a deep breath. okay? and tell me what's going on. >> i don't know. >> reporter: michelle ran across the street to a neighbor's house, desperate to hide. >> she's not answering the door, okay? >> do you want me to stay on the phone with you? >> no. i need to call my mom. >> okay. call your mom. i'm going to get them en route. >> it was a voice that scared me. you know you pick up the phone. you hear one of your kids on the phone, and you hear crying. >> reporter: kathy raced over there, found michelle sobbing on the curb. >> and she's "i got to get to him. i got to get to him."

i just kind of grabbed my daughter by the shoulder. and i'm like, "michelle, he's gone. he's gone." >> reporter: so he was. dead on his own kitchen floor. a young wife is now a widow and the horror of what she witnessed is unforgettable. >> reporter: is it a sight that lives in your mind a lot? >> a lot. >> her family's good life suddenly gone -- or maybe it hadn't been so good. >> he was kind of embarrassed to have to come and get money from me. >> money, is that a clue? ntures with toothpaste or plain water. and even though their dentures look clean, in reality they're not. if a denture were to be put under a microscope, we can see all the bacteria that still exists on the denture, and that bacteria multiplies very rapidly. that's why dentists recommend cleaning with polident everyday. polident's unique micro clean formula works in just 3 minutes,

>> reporter: they are burned into michelle despain's brain. the images of that awful afternoon. shadows in the hallway. her husband. his blood. >> him laying on the floor. >> reporter: is it a sight that lives in your mind a lot? >> a lot. oh yeah. >> reporter: outside, a crowd of police, and friends and family, and curious neighbors, gathered on the street below marc's house. among them, in an awful state, was marc's sister jacque. >> you know, everything was wrapped in tape. and police officers, "you can't cross here. you can't do this, you can't do that." i don't know. i just wanted to hold his hand or something. >> reporter: detective vic brooks was on the other side of that police tape. >> when i first walked in, i noticed that were some papers

that appeared to be knocked on the ground. and there was some broken glass and stuff like that on the floor. >> reporter: investigators snapped photos of the chaos. drawers pulled out in a bedroom. clothes thrown into the bathtub. a jewelry case toppled over. like somebody was looking for something? >> possibly. >> reporter: they asked around the neighborhood, did anyone see any strangers that afternoon? and yes, someone did, investigators told prosecutor, scott ellington. >> an african american was seen in the neighborhood wearing a certain colored shirt. >> reporter: it wasn't just that. later somebody said they saw an aging and beat up blue mercedes circling the neighborhood. so, thieves casing the house? maybe. and yet, as detective brooks looked around the house, he could see this just didn't have the hallmarks of a robbery. the valuable stuff -- tv sets, guns, computers -- were untouched.

and look at this photo. sitting next to marc's keys and a cell phone on the kitchen island, is a container of ice cream. >> it appeared that he had just walked in and set these items down, and then was caught totally off guard. >> reporter: all of that seemed to shriek of a planned ambush dressed up a little to look like robbery. the way investigators pieced it together, somebody was waiting for marc to get home, then crept up from behind, shot him twice. >> he had suffered two gunshot wounds, one that appeared to have entered on his left side, and then another shot that he had sustained to his face. >> reporter: that was a kind of -- what is a kill shot or something? >> yes, sir. >> reporter: somebody making sure. >> it appeared so, yes. >> reporter: why would someone want to kill marc despain? >> i was so confused. i just -- i didn't think marc had any enemies. and i didn't know why anybody would want to kill him. >> reporter: detective brooks soon discovered a possible

reason. even though they'd been living lavishly, marc had serious money trouble. >> he was kind of embarrassed to have to come and get money from me. >> reporter: it was a couple of months before the murder, said michelle's mother kathy. marc asked her for cash to help pay for michelle's birthday present. >> you know, that's very unusual. because usually they just go out and buy whatever they want. >> reporter: not anymore. that summer, 2011, jonesboro real estate was far from recovered. many of marc's rental properties were underwater. the bank was closing in. tenants were being forced out of their homes. so -- >> you know, was anybody upset with marc? was this any of his tenants? could this have been somebody like that? >> reporter: and then, an ugly little surprise crawled out of marc's own troubled family. marc and his parents were lobbing lawsuits at each other over some shared property. the prosecutor heard that marc's dad, jack, was a hothead. >> jack was very, very angry at

marc for mishandling this property that they co-owned together. >> reporter: yes. but it went deeper than that, went to a very dark place, as you will see. and because of it, marc hadn't spoken to his parents in years. so when jack showed up at the crime scene, the suspicion was, well, audible. michelle's dad, carl, started yelling at him. >> cursing very loudly. calling him all kinds of names. >> reporter: but what was he saying? >> there's that son of a bitch, jack despain. >> reporter: did you think jack was somehow responsible? >> oh, yeah. marc had told multiple people, "if anything ever happens to me, y'all look at my dad." >> reporter: so, of course, detective brooks invited jack down to the police station. just maybe this mystery would have a quick, if very disturbing, solution. coming up -- a young girl makes a troubling accusation

that defines a family -- >> oh my god. could this have possibly happened? >> but was that the motive for murder? was it even true? when "dateline" continues.

♪ >> reporter: it's an unpleasant thing to think about. parents murdering their own children. but it happens. is an old story, frankly. some awful glitch, perhaps, in the human recipe. had it happened here, in jonesboro? suspicion fell quickly on marc's dad, jack despain. michelle's mom heard about it when she called to tell a relative that marc was dead. >> somebody's murdered marc. and he was like, "oh my god." he said, "have they found jack despain?" >> reporter: he thought right away it was jack. >> uh-huh. >> reporter: because anyone close to jack and his family knew, a poison far more potent than money had come between father and son. >> i never saw it coming. i don't think marc ever saw it coming. >> reporter: it began, said michelle, when her 13-year-old daughter told them an ugly

story, that her grandpa jack asked her to take nude photos of herself on his phone. marc called a family meeting. >> marc told his dad, there's a problem. we want to help you. you know, we're not here to point fingers at you or judge you. >> reporter: jack swore he did nothing wrong. marc called in the police. tana, jack's wife of more than 30 years, left him. moved in with marc and michelle. well, how do you prepare for a thing like that? >> you don't. you don't prepare -- >> reporter: well, what is that like? >> you just -- your mind is -- is in overdrive, you know, trying to think, you know, "oh my god, could this have possibly happened?" >> reporter: but after the police interviewed the girl, and then jack, and then the girl again, and heard her story change, become more elaborate, the investigation was dropped. and tana, driven with guilt for ever suspecting jack abused his granddaughter, went back to him and begged forgiveness.

>> the man i've been married to for over 30 years and went to high school with, and then doubting him, and knowing i shouldn't have. >> reporter: but marc and michelle, believing the girl, never spoke to his mom or dad again. cut them off from their grandkids. disowned marc's sister when she took jack's side. >> i believe dad 100%. i don't believe he had anything to do with it. >> reporter: so that was the ugly backdrop to the murder investigation. and detective brooks would have to figure out if this years-old unproven allegation had so eaten away at marc's dad that it pushed him over the edge. time to meet potential suspect number one. >> i'm going to close that door, mr. despain. >> reporter: detective brooks sat down with jack in an interrogation room and watched the man fall apart. >> i can't.

>> reporter: was this true grief the detective was witnessing? or regret? or guilt over something jack had done? or hadn't done. >> i was too late. >> reporter: too late. what did he mean? jack didn't shy away from discussing those abuse allegations. here's how it happened, he said. >> she had taken some nude photos of herself and sent them to her boyfriends. >> reporter: jack said he found out the girl was sexting, confronted her, said he was going to tell her parents. but she got to them before he did, jack said, and invented the story to get out of trouble. >> so they took her side, i guess. they took her side and said i was the bad person. >> reporter: jack told us the same story, eager, he said, to finally set the record straight. you didn't ever ask her to take pictures of herself and give them to you? >> no, no. >> reporter: but the accusation, said jack, almost destroyed him.

>> i was at home. i could have opened up my own whiskey store, i think, with how much whiskey i drunk for two months. and typically i don't drink. but that was just to kill the pain. >> reporter: because everybody assumed that you were abusing your own granddaughter. >> yes, yes, yes. >> reporter: the detective wondered, did jack's pain drive him to seek revenge on his own son? no, said jack, no. he wanted to reconcile with marc, not kill him. >> i know i ain't talked to my son in four, five years but i loved him dearly. >> reporter: anyway, when marc was murdered, said jack, he was miles away at his own house. >> i was on the roof trying to put some shingles on. >> reporter: that alibi would have to be checked out, of course. but even before detective brooks had a chance to do that, other members of the family came down to the police station and told him, don't be fooled by jack's tears.

he was an angry, possibly violent man. >> he said, "i will ruin you and your family." he said, "for you all accusing me of this." he said, "i will see you ruined." >> reporter: this is michelle's dad, carl. the man who'd been cursing jack out on the street right there at the murder scene. >> if i was going to point a finger at anybody, if that's what you're asking, i'd point it at jack despain. >> reporter: detective brooks could plainly see this was a family with a troubling history. so he made a decision to attend marc despain's visitation, take a look around, see what his gut would tell him. i saw a note where you, in your case file, you wrote, "this has to be one of the strangest visitations i have ever attended?" >> yes. it was just a cold feeling. it just did not feel right. >> reporter: was the killer sitting among the mourners, planning a next move? coming up -- a family feud at the funeral. >> she calls the police on us. >> and somebody else calls the

police with a tip that could crack the case. >> reporter: that's a nice little gift. >> it was. ♪ this is the time ♪ the time for harmony ♪ let love be the song ♪ that everybody sings ♪ fill the air with joyful noise ♪ ♪ ring the bells and raise your voice ♪ ♪ let there be peace on earth ♪ ♪ let there be peace on earth ♪ music starts and pgucci guiltyout the fragrances for him and for her. let's get these dayquil liquid but these liquid gels are new. mucinex fast max. it's the same difference.

♪ back to our story. a young father has been murdered and the search for his killer is focussed on those closest to him, for good reason. his family, and his wife's family, are divided by a bitter feud. that fight has gotten so ugly that even his funeral is about to be turned into a battleground. here again is keith morrison. >> reporter: michelle and marc, just children really when they got married. now marc was dead. gunned down in the family kitchen. and michelle had to plan his funeral. she was barely functioning, she said. >> i couldn't even tell you who was at the -- you know, who was there.

it was just a blur. it all still just feels like a blur. >> reporter: but there was one thing she was clear about. marc's parents and sister were not welcome at his funeral. what was the funeral like for you? >> oh, it was awful. we couldn't sit down on the main level with family. >> reporter: why? >> michelle wouldn't let us. she barred us. >> reporter: it was the same at the cemetery. >> she's literally trying to get him in the ground before we can even walk up. >> reporter: you mean get them to fill in the grave? >> yes. so, we just immediately jump out of our car and we start rushing to the graveside. and she calls the police on us. she calls the police at my brother's funeral. >> reporter: yet, for all the chatter about jack, that he might have killed his own son, detective brook's instincts said no. jack's alibi checked out. he was fixing his roof afternoon

of the murder. and those tears in the interrogation room -- >> i did not feel anything as being fake from mr. despain. he appeared to be a broken man at that time. >> reporter: so what to make of the fractured family and all the bad blood now tangled up with so much grief? detective brooks thought back to his interview with michelle's dad, carl, the man who pointed a finger at jack on day one. >> he told him he didn't want to have nothing to do with him. >> reporter: carl said he'd been in marc's house not too long before the murder, dropped off some rent money. >> why didn't they shoot me instead of him? i had the money in my hand. >> reporter: interesting timing? coincidence? or, as detective brooks wondered, did carl have something to do with the murder? maybe not. carl's alibi checked out. surveillance cameras, in fact, caught carl right where he said

he was around the time marc was gunned down, meeting his daughter at the bank where she worked. he could not have shot marc. while the investigation continued, marc's parents spent time at the cemetery, finally able to do what they couldn't when their son was still alive. >> we'd talk to him. talk to marc. >> and rainy days were the worst. i didn't like rainy days. >> reporter: what do you mean rainy days? >> i didn't like him getting wet. i knew he was in heaven. but i just didn't like the rain on him. >> reporter: and then? pure luck, really. remember how neighbors reported seeing an african american stranger in the neighborhood? now, someone called the cops with a tip. somebody who matched that description was actually boasting about shooting marc despain. that was a nice, little gift? >> it was. >> reporter: didn't take them long to find the guy. street name, qualow. real name, terrance barker.

and he was nervous. >> i can see your heart beating through that shirt right now. i know you're scared. >> reporter: he denied everything. >> i don't know what to tell you, man. i didn't do this. >> reporter: detective brooks wasn't buying it. because by then, the police also tracked down the driver of that beat up blue mercedes seen near the house before the murder. and he told the cops he took qualow to meet a man in a church parking lot. and that man wanted a job done. was that job murder? >> i didn't do that. i did not do that, sir. >> reporter: by now detective brooks had been working night and day for a week. his store of patience ran out. >> this is serious [ bleep ] to me. i've got three kids that are laying over there crying. >> reporter: was it that angry speech or another long night in his cell? the next day, qualow, came clean.

for a promise of 7 to $10 thousand, still unpaid, he said, he took the job to shoot and kill marc despain. >> you fired the first round and that round hits him where? >> it hits in the chest area. >> reporter: he didn't know marc from adam, he said. it was the man from the parking lot who took him to marc's house, told him where to lie in wait for marc, gave him a gun. and then qualow said something rather surprising. >> i've been thinking, like, man, what the -- what -- what -- what in the hell kind of people do [ bleep ] like that? >> reporter: the shooter who executed a stranger for the mere promise of a few grand, said he was appalled. not at himself, at the man who hired him. >> people are something else, man. you know, it's -- especially people that you think care about you and love you. they're supposed to be -- these are the same [ bleep ] that be in your face plotting on you. >> reporter: if the hitman was telling the truth, detective brooks' hunch had been right.

someone who claimed to love marc, also plotted his death. but who? coming up -- michelle confesses to an affair. >> my dad didn't know that. marc didn't -- i mean, nobody knew that. and there was another surprise. >> there were two insurance policies, each for the amount of $500,000. >> when "dateline" continues. ♪ phil! oh no...
