you had to love him for that. i fell back in love with him. ♪ >> deborah: a larger-than-life businessman gunned down in his office. >> david: will the discovery of his secret double life lead to the killer? an all-new "20/20" starts right

now. so, in broad daylight, a man is shot dead in his place of business on a busy street? >> i knew as soon as i saw it. i knew that he was gone. >> just two blocks behind me, bob eidman was found robbed and murdered. >> bob eidman was shot three times, by that third shot is being an execution. >> i just -- all the way there saying, "no, no, no, no, no, no. no, bob. no, bob." >> there were just floods and floods of police cars coming in and just total chaos. >> we're with the major case squad. >> they only have five days so the clock is ticking. >> diane found out on the site that her husband had been murdered? >> yes, she did. >> she makes this statement, "something like this has happened before." >> there were numerous individuals that could have done something such as this. >> he asked me a question that just kind of floored me.

he said, "we're trying to find out about your brother's lifestyle." >> what is it like to all of a sudden learn that there's this whole other secret part of his life? >> people are going to find out some stuff they're probably not gonna like. june 8th, 2007, was a typical day in st. charles. it was a sunny day. i was proceeding southwest here on first capitol drive. >> so, it was about to break 80 degrees on this friday morning around 11:00 a.m., and as officer dean mayer's patrol car is making its way toward interstate 70, a mail carrier was on her rounds, too. this security video showing her dropping off mail at a strip

mall grocery store, then driving her truck a few doors down to enter the office where bob eidman sold car insurance. nobody heard her first scream. >> police! >> our mail carrier was running up the street, and she was flailing her arms and she was yelling for the police. >> deborah kennedy was the first person to hear those desperate cries and tried to catch up with her as the mail carrier ran into traffic on the busy road before officer meyer spotted her. >> i saw a mail carrier running up the hill with a phone in her hand. >> stop, please help. there's a man, i'm delivering the mail, he's lying on the floor with blood all over him. >> i asked, "what's going on?" and she said bob was laying on the floor and he had blood on his face. >> and she tries to investigate what's going on. she goes into bob's office and gets the shock of her life. >> i went inside to see if i could help him.

and when i walked in, there was plenty of blood. i watched his chest, his chest didn't move. i knew as soon as i saw it. i knew he was gone. let me breathe for a second. >> it was st. charles' first murder of 2007. and right from the start, it was the kind of thing that just isn't supposed to happen here. that's because st. charles, missouri, is an idyllic bedroom community just over the bridge from st. louis with a historic downtown, and historic values as well. i guess the idea is that you're supposed to shed the stress of the big city as you come across the wide missouri river and land here. but as we know, money woes, lies and rage and desperation, the

grip of fear, they do not stop at the river's edge. >> now we've got a whole team of officers from the st. charles police department. they've converged on the scene of bob eidman's murder. >> there were just, i mean, floods and floods of police cars coming in and just total chaos. >> immediately i responded to the area, to the scene. bob is laying on the floor between the two desks. he's laying on his back and there's a pool of blood around his head. >> bob eidman was shot three times. the first shot was superficial. it was a grazing wound to his chin. the second shot was to his neck, shoulder area, which knocked him down. >> according to st. charles homicide detective, don stepp, the third and fatal shot had been fired through bob eidman's left eye as the assailant stood over his prone body. >> i would definitely classify that third shot as being an execution.

>> this was an insurance office, and it was a fairly open area. we collected bullet casings, bullets, bullet fragments. we would mark the position, set up little yellow tents called photo markers. we would photograph it. we dusted for fingerprints. you are hoping that maybe you will find one fingerprint that may lead to a particular suspect. >> police are seeking out anyone who might've spotted something that morning in bob's office. with her office directly below bob's, deborah kennedy didn't see anyone, but she might've heard something. >> i think it was probably around 10:30 or 11:00, a friend of mine had come in. you know, i heard a couple noises and we both kind of looked at each other, and then i heard a big thud on my ceiling and we're kind of like, "what the heck is bob doing up there?" and so, being the way i am, i yelled up through the rafters,

"hey bob, keep it down. i'm trying to work down here." >> we came to the conclusion that those loud bangs that she heard was the gunshots in bob's office. >> police quickly work to gather information about the victim. his name is bob eidman, he's 48 years old, he was married for a very long time, had no children, and worked in the insurance industry. >> but just recently, like the past two years, had just started this new company. he'd got a franchise. he just started that on his own. >> as news begins to spread that something bad has happened at bob's office, concerned friends and associates in the insurance business, they rush to the site. like the longtime colleague who asked that we call her dana. what made you want to go over there? >> that's my friend. i wanted to make sure he was okay. i remember locking up my office. i had a client in there, and she

saw how distraught i was. and i'm just in the car, just all the way there saying, "no, no, no, no, no, no, no, no, no. no bob. no bob." >> what happened when you got there? >> of course there's spectators. so, someone said that someone got shot. didn't see bob, didn't see him waving in the window, didn't see any sign of him at all. and then, when they took his body out of the office, we knew it was bob's body because he was a big guy. >> what's that moment like? >> oh, my goodness. it was the worst. >> local reporters have arrived on the scene as well. those reporters notice that a woman pulls up and it turns out that she is the now widow of robert eidman. her name is diane. and diane approaches the reporters asking them if they know what's happening. and the reporters are saying that they feel uncomfortable telling her about her husband, so they direct her to the police. >> diane said that she hadn't heard from bob all day, which

was odd. and she kept trying to call him, and he never answered the office phone. so, when she shows up and seen all the police cars, she knew something had happened and she identified herself. >> diane found out on the site, didn't she, that her husband had been murdered? >> yes, she did. >> as investigators comb the area looking for video of any potential suspects, they happen upon this grocery store just a few doors down from bob eidman's office. inside, they take note of the security camera that captured the mail carrier earlier that morning. it was right about there, pointed directly towards the front door. once they get a look at the video it recorded, it's the (woman 1) eczema... video it recorded, it's the first big break in the case. isn't always obvious.

bob was taking too great a risk, with the form of payment he did take. >> so he would accept cash, against a lot of people who advised him not to take cash. >> though he was known for accepting cash, he doesn't have a safe. instead, police learned, bob would put the cash he received from clients into a far less secure place. >> there was a drawer in bob's desk that was locked and you'd have to use a screwdriver to manipulate the lock to be able to open it. >> when police managed to open that drawer and check the cash box, oh, there's money inside, about $200. >> there was no forced entry. but it could have absolutely been a robbery. i know one of the things they were looking for was bob's wallet missing. >> and you're looking for anywhere that somebody might have thrown something, like bob eidman's wallet. >> from the top of the roof all through the grass, ditches, sewers, everywhere. we could not find the wallet. wallet's going to be 90% of the time in a man's back pocket. >> and to get that wallet out, you would've had to struggle

between the wallet and the inside of the pants, which caused some friction. i recommended that we cut the pants pockets out and send them to the crime lab. we just thought maybe a sample of skin cells could be found inside bob's pocket. >> when we touch something or brush up against something, some of our dna is transferred to the other object. if they're located, those skin cells can be broken down into dna. >> so you were checking for dna everywhere else, but this was just out of the blue. you just thought, you know, might as well give this a try. >> yes sir. it was the first time that i'd ever heard of anybody's pants pockets getting cut out. >> while one team is feverishly working to gather physical evidence, another team is talking to anyone they can find, talking to family, friends, anything that will help them glean information about bob eidman. >> bob was a big teddy bear. he was friendly, he was bubbly,

down the street from brooke's insurance. >> and it was a bowling alley that we all bowled at, so at first we all thought it was tied together. >> so people wondered if there was a connection between the two robberies. >> and we looked at that, seeing if they were connected. and in the course of that investigation, we were able to eliminate it from being a part of this case. >> police are knee-deep in bob eidman's murder investigation. and they come upon a really interesting scene. it's an abandoned, crashed white car. and when they track down the owner, well, there's a couple of really eye-popping pieces of information. >> he had bloody clothing on, and he also had one of robert eidman's business cards. why does he have bloody clothing? is it his blood?

is it bob's blood? we have some questions we need answered. this could be it. >> it blew my mind like, "whoa." >> travis wade ensley is about to blow a lot of minds at police headquarters, where leads in bob eidman's murder have been hard to come by. >> the car that i wrecked was a white four-door saturn. >> which might've looked like the car that was captured on the footage. >> exactly. and the next thing i know, i'm at a st. charles police station getting questioned for murder. >> police now feel that he has a lot of explaining to do. so as travis recalls, his story goes kind of something like this. >> i needed new insurance on my car. my buddy's like, "check this guy out." and called him up. he gave me a good rate. and then a week later, i'd been out, had a couple drinks. i wound up wrecking my car right by my apartment. my airbags deployed, and it knocked the sense out of me, and i staggered down the hill right

to my apartment, didn't remember nothing. next day i woke up. i walk out my door and my car's not there. >> so travis calls police to report his car as stolen, but then is stunned to suddenly find himself a potential person of interest in a murder. >> i was scared to death. >> they were coming at you. >> yes, they were coming at me pretty good. >> travis has what seems like a likely story about why there's blood on his shirt. he says that when he crashed his car, he got a bloody nose. cops will check out his story, so they're not quite ready to clear him. >> and they went and looked into my alibi and this and that. they're like, "okay, yeah, he's not the guy." >> now police turn their attention closer to home, to bob eidman's widow diane. it is quite routine for police to look at the spouse of someone who's been murdered. >> when bob's wife diane was advised that bob had been

murdered in his office, she didn't have a great reaction. >> while diane does appear to be upset in this photo, some detectives at the scene felt she was not overly emotional. >> i don't want to say it didn't seem like a surprise to her, but she wasn't reacting in a manner that i thought a wife would react when he found out her husband was shot. >> that struck me, and i'm sure several detectives, as unusual. >> is she in shock? is she in denial? is she involved in this? >> then there's detective stephanie kaiser. already a veteran sex crime investigator, kaiser was respected for her sensitivity and understanding with victims. >> that would be completely normal in a shock situation like that. there is no such thing as a one-size-fits-all when you're talking about trauma. because to be able to process that would take some time. they're moving slow. they can't think. so i make nothing of that behavior.

>> now detective kaiser is about to become the st. charles police department's diane whisperer. >> diane eidman became my lead. we were assigned to take her from, sadly, the scene. >> diane wants to go to bob's parents' home so that she can break the terrible news to them. and during that ride, diane talks about how she is the manager of the kitchen at the local hospital, and she also offers more information about her beloved husband. >> she says that there was financial problems. >> when you say financial problems, what do you mean? >> they were having a tough time paying bills. according to diane, there wasn't much cash coming in. the business itself was struggling. >> detective kaiser continues talking with diane, and she makes a note that diane seems incredibly forgetful. she can't remember her own social security number. and the detective asks her about any existing insurance policies.

>> she was upfront that, "yes, i have a life insurance policy through work." >> diane initially gave us an answer that she thought they had a couple of small policies, approximately $5,000. >> not much, right? >> not much. >> so diane was pretty direct with me. i think she'd had a lot of questions asked of her, and then just kind of tells me boldly, "i did not do this." >> these conversations with diane will shape and reshape the police investigation into bob eidman's murder. at the end of that first day, diane sounds like every other resident of st. charles. she is terribly afraid. >> it's just dawning on her, "wait, i'm not safe either." i have to act to get her extra patrol. and i did. but you have to still go with where the evidence leads. >> and no one knows yet where that evidence will lead, especially in the wake of the very first astonishing story that diane eidman tells

at the time of his death, bob eidman had been married to his wife diane for more than two decades. and yet, even those closest to him could find diane to be something of an enigma to them. >> not very outgoing. >> no, not very outgoing. she was just kind of shy and quiet. i mean, she just didn't really have a lot to say to anyone really. >> when you would ask bob about diane, what kinds of things would he say about her? >> his famous saying was, "she's not the person you think she

is." and i never knew what that meant. >> now, detective kaiser was reeling from the incredible story that diane had told her. >> she makes this statement, don't take this as a confession, but something like this has happened before. and i'm not quoting diane at this point, but somebody broke into the house and shot my dad. so, when i asked them did they catch the person -- >> how did she answer that question? >> she said they thought my mom shot my dad. >> and, we were wondering if lightning had struck twice in the same place. >> diane boelling eidman, seen here on her wedding day in 1978 with her father jerome, was just 26 years old when he was murdered inside the home he shared with his wife lenore, diane's mother. the murder case that made

headlines in this region all began when a call came through in the wee hours on the morning on april 6th, 1984. gordon adams was an officer with the st. louis county pd. what went out over the radio when you heard the call? >> as i recall, like i say, it came out as a home invasion with someone shot. and so that's what we would consider a hot call. well, when i arrived, it's 2:30 in the morning, maybe 2:35, and so it's dark as it can be, but i immediately went to the door, knocked on the door, and lenore answered the door, and the hair is pristine, and she's standing there in a kind of sheer nightgown, and she says, "my husband needs help, he's in the bedroom, he's been shot." >> what are you thinking when you're hearing this story for the first time? >> i mean, she didn't strike you as a woman who woke up in the middle of the night to find her

husband murdered. no tears. the hair was all done. and i'm trying to get information for my report, she actually lit up a cigarette. i'm thinking, "this is your husband, he's just been murdered." she didn't have any emotion at all, almost. >> david barron was a detective with the st. louis county police assigned to the case. so lenore boelling was asserting that an intruder had come into the house, somehow found her husband's service revolver, used that service revolver to kill him, and then left. >> that's what she was saying. >> how did that strike you as a plausible story given your years of experience in law enforcement? >> it was an improbable set of circumstances. and to throw into that, the garage door was open about a foot. >> okay, that garage door over there -- >> that's correct. >> -- was open a foot?

>> it was up to detective stefani kaiser, the diane whisperer, to broach the delicate subject with bob's widow while interviewing her at the eidmans' home. kaiser said diane told her that she'd learned of her husband's relationship with the man after discovering an email between the two, that bob denied having an affair. but it was the tone of that email which had deeply hurt her feelings. >> she describes it as, "he's telling him intimate things that he hasn't told me." she's telling me, "i felt hurt, because he wasn't speaking to me that way." so, they're married -- >> what do you think she meant when she said that? what kinds of things were they saying to each other? >> i didn't ask the specifics. but i'm just talking to her about it, "did this happen?" could, potentially, could this be a motive? >> in det. kaiser's account, diane seemed to be struggling a little bit with the nature of her husband's relationship to the man, or what they did during their time together. >> when i'm interviewing diane,

"well, that's what he's saying. diane, what say you?" she said, "i told him it was over. i told him he was going to end that friendship." but she said, "i don't know if i was yelling and screaming." i go, "that's what he's saying. i'm just asking." so -- >> but she laid her foot down. she gave him an ultimatum.

investigators and asked if we could do the dna on the case. >> with almost every angle of the case having been explored and explored again, it all comes down to what krey could uncover with the dna analysis. >> if we were gonna swab the back pocket of a pair of pants, we would cut open the pocket, swab the edges, hoping to get possible dna. once i get a swab, i process it and cut the tip off and put it in an extraction tube, and then we load it onto a genetic analyzer that ultimately produces a dna profile. >> but given the cold case backlog, it takes several more months for the dna to be processed. and when the results come back, investigators get a major break that heats up this cold case. >> i developed an unknown male profile. it was a mixture of two people.

one of those persons was the victim, robert eidman, and the other one was an unknown male. >> i knew once we obtained the dna profile, the identity of the individual in bob eidman's pocket, i knew that was the golden ticket. i knew that was when we were going to be able to close this case. >> that unknown dna could lead investigators to bob's killer, so krey enters the profile into codis, that's a law enforcement database. hours later, there's a hit. >> it hit that same day. and the next day, state gave me the name. >> the dna doesn't match bob's wife, or his secret lover, or anyone else the police had been looking into. instead, it comes back to someone who was never on the investigators' radar. >> what did you learn that person's name was? >> paul white. >> when the name is first

discovered, detective stepp is otherwise engaged. >> i was on a traffic detail, directing traffic. >> do you just want to run up and down the street and tell people we've got our guy? >> i was very shocked. my mind was not on directing traffic at that time. >> what did you do then? >> i started researching paul white. >> turns out, paul white was no stranger to law enforcement, having served 15 years in prison for robbery. >> when they got the dna match, don had contacted me and said, "i'm going to solve this." and i truly believed him. i got to give him a lot of credit, you know, he did a lot of old-fashioned work. >> this new lead poses even more questions for investigators. could diane have hired paul white to kill bob, or had white acted alone? when the dna came in, that didn't seem to exclude her either. the idea being maybe she had hired somebody. >> yes. i mean, it was worked all the way through.

>> you now have paul white's dna on robert eidman's pocket at the time of his murder, right? >> yes, sir. >> so, i assume you want to talk to paul white? >> yes, sir, i do. >> and paul white was not hard to find. >> paul white was incarcerated at the time when the dna came back. >> how you doing? >> and so, in september 2010, detective stepp pays a visit to paul white at a maximum-security prison in fulton, missouri, where he's serving time for forgery. >> do you have any idea why we're here? >> mm-mhmm. >> i wanted him to know right off the bat that we knew he was there. does this guy looks familiar? >> mm-mhmm. >> you've never seen him before? i wanted the truth. i wanted to get a confession from paul. >> i've got your dna in his back pocket.

>> and will that touch dna evidence be enough to get that confession? >> white leaned back in his chair, he laughed. >> it's -- it's impossible. >> it's not. >> it's impossible. there's no way in the world, it's impossible. >> what are you thinking when he does that? >> i'm thinking this is going to be a long interview. >> i'm getting taped and >> i'm getting taped and stuff -- and what the -- can keep coming back. start to break away from uc with tremfya... with rapid relief at 4 weeks. tremfya blocks a key source of inflammation. at one year, many people experienced remission... and some saw 100% visible healing of their intestinal lining. serious allergic reactions and increased risk of infections may occur. before treatment, your doctor should check you for infections and tb. tell your doctor if you have an infection, flu-like symptoms or if you need a vaccine.

more than two years after bob. e differently man was robbed and murdered at his insurance office, tests of dna taken from his back pocket are in, and there's a match. >> that individual is in the department of corrections in missouri. >> what did you learn that person's name was? >> paul white. >> as investigators dig deeper into paul white's background, they uncover a possible connection to bob. it's been hiding in plain sight. >> there was numerous files in bob's desk, and there was a file containing paul white's name. >> among those files is an application for auto insurance. two names are listed -- cherie white, and her husband paul white. >> paul white's wife's file was on bob's desk? >> yes, sir. >> what was it doing there? >> i think when mr. eidman had seen the car pull up and saw paul white exiting the vehicle,

he was grabbing cherie's file, to be ready so when he came in. >> investigators quickly clear cherie white as a suspect in bob eidman's murder. with the trail of evidence now leading directly to paul white, detective stepp decides it's time to meet face to face. >> this is where the magic happens. >> doesn't look all that magical, does it? >> no, it doesn't. >> what happens to people when they come into a room like this? >> we get to the bottom of facts. this is where people have an opportunity to tell us about what they've done and tell us their story. >> since paul white is already serving a prison sentence for an unrelated forgery charge, he's literally a captive audience. let's go back and talk about some of your strategy, as you were going to talk to paul white. >> paul, i believe, was in a little bit of shock after all these years. two detectives showing up from st. charles city? he did not expect that to happen that day. >> do you have any idea why we're here?

>> mmm-hmm. >> okay. >> are you thinking the long game at this point, or do you think he's going to start telling you stuff that he knows at that first interview? >> i'm thinking to myself, the dna itself is probably enough to get an arrest warrant. but i didn't want just an arrest warrant. i wanted the truth. >> before i ask you any questions, you must understand your rights. you don't have to make a statement, or answer questions. you have the right to remain silent. do you understand that? >> uh huh. >> put your initials there, paul, for me. i think initially, paul white's attitude was very kicked back, relaxed. >> first of all, do you know a guy named robert eidman? >> mmm, mmm. >> never heard of that guy. >> mmm, mmm. >> i even put a picture down in front of him, and asked him, "do you know this individual?" this guy look familiar? >> mmm, mmm. >> never seen him before? >> eventually, he came back around and said, "yeah, i thought that was his wife's insurance man." >> that picture i showed you? that's robert eidman, okay? you said he kind of looks familiar. >> yeah, that's the guy we got the insurance from. >> i explained that we were working a homicide investigation, and i explained that his dna was located in his back pocket. >> do you think there's any chance that your dna is going to pop up inside that crime scene?

>> from the robbery? >> from the robbery? >> no. >> you come to prison, they take your dna. your, your dna pops up. you know where it pops up? swabbing a back pocket of my victim. your dna shows up in this guy's back pocket. >> ain't no way in the world. >> why don't you think that? >> you said that he got robbed. i've never robbed the guy. i've been in there one time, and to get insurance, so that's -- >> exactly. >> ain't no way in the world. >> you're telling me you've been in there one time and your dna shows up in this guy's back pocket a month later? >> that don't even make sense. >> exactly. with your story it doesn't make sense. >> again and again, during that first interrogation, you tell him, "i've got your dna." you must have told him, what, ten or fifteen times in the course of that conversation, right? >> at least ten or fifteen times. he kept saying, "there is no way," repeatedly.

he did not believe it. >> it's impos -- there's no way in the world. it's impossible. >> paul, it's not impossible. >> okay. >> i'm tellin' you -- >> well, i'm -- i'm telling you, i know it's impossible. there's no way in the world. >> then how did -- then how did it get there? >> i don't even feel like it was there. it's impossible for it to be there. >> after white's adamant and repeated denials about that dna evidence against him, investigators uncover another critical piece of evidence. >> i ran every kind of data history check on him. the big point with paul white was i found out that a neighboring law enforcement agency had issued a ticket to paul white, after our homicide, in a white ford focus. >> that's right, a white ford focus. and, remember, that's the very same vehicle make caught on a surveillance camera the day bob eidman was murdered.

>> paul white was a passenger in that vehicle, and the driver was identified, via tickets, as cleo hines. >> why was the car stopped in the first place? >> registration on the vehicle. >> the registration on the vehicle was out of date? >> that's correct. >> who was the driver of the car? >> the driver of the vehicle was cleo hines. >> what was significant about that? >> we later learned that cleo hines was living with paul white, and his girlfriend was best friends with paul white's wife. >> so, they had a long-standing relationship? >> yes, sir. >> what was the indication that you had that cleo hines might've been involved in the murder of robert eidman? >> it was cleo hines' vehicle. >> you were sure of that? >> i was sure of that. i had a couple other officers contact cleo hines, and they arrested cleo hines and brought him to the st. charles city police department. >> does cleo hines knows a secret that could solve bob eidman's murder? >> you know a man died, right? you know that? somebody pulled that trigger.

after several years of lead after lead turning cold, the investigation into bob eidman's murder is now heating up as lead detective don stepp zeroes in on a new suspect -- a man named

cleo hines. >> i was going to take the same approach with cleo hines as i did with paul white. are you the hardened criminal, or are you a guy that made a mistake? >> let's talk about the robbery. dude, i know all about it. i told him we had a positive i.d. of his vehicle. we had a positive i.d. of a focus. a white, four-door focus. you know your vehicle is on a video? did ya know that? you know that mexican grocery store? there's a video camera inside. so i seen you pull in. now, you didn't just pull around once, did you? >> no, like, twice. >> you pulled around twice. >> yeah. >> that's on camera -- >> yeah. >> -- that you pulled up. >> he knew he owned a white, four-door focus. he knew he was involved in this. there was no way that he could fight that. >> unlike paul white, hines immediately starts talking, saying white approached him the day of the murder. >> he got a gun in his hand.

>> okay. >> and he wakes me up out of my sleep and put it to my head. >> he told you he's going to do a robbery? >> i basically already knew that because of the gun. >> okay. >> and how he was acting. and he didn't -- he didn't have no money. >> it took a very short time, and cleo just started talking and talking and talking. >> what kind of handgun do you think it was? >> it looked kind of like a 9 millimeter glock. >> a 9 millimeter glock, the same type of handgun investigators determined was used to murder bob eidman. but the question is, who pulled the trigger? >> somebody pulled that trigger, okay. >> it wasn't me. it was him. >> okay. >> and cleo wanted to give his side of the story to defend himself against whatever paul might say he did. >> i take him to the insurance place and drop him off. i'm outside. he goes in, and about five minutes later, he comes back out. >> did he have gloves on? paul? >> mm-hmm.

>> yeah. he had gloves on? >> a white -- white gloves. white gloves. they were, like, cotton gloves. >> paul white had been wearing gloves, so paul white absolutely wasn't going to say anything because he believed his dna couldn't have been located because he was wearing gloves. >> i don't even feel like it was there. it's impossible for it to be there. >> so if a perpetrator was wearing a cotton glove, when they go into the pocket, and digging around, they could leave that dna that's already on the exterior inside the pocket. also, if the individual is sweating, it could actually soak through the glove and leave dna behind that way. >> what did he do with those gloves after, uh, the shooting? >> he burned 'em. >> in the barbecue pit? >> yeah. >> armed with cleo hines' confession, stepp hits the road to fulton prison once more for another crack at paul white. >> and i'm going to tell you right up now, i got a full confession from cleo hines, okay? he told me everything.

>> but even after detective stepp reveals cleo hines has accused paul white of being the gunman, paul white doesn't blink. >> if you got cleo saying that i did this and that, he's evidently lying to you. and i don't know why he would even say that i would put a gun to his head and force him to do something. >> it's hard to do an interview, to get a confession from somebody for a murder. it's really hard to get a confession from somebody for a murder inside prison. >> white is arrested the next day and he's charged with robbery and murder and could be facing life in prison. now with the pressure turned up so high, will he finally change his story? >> i've asked you three times. drove 87 miles one-way to ask you these questions. >> hypothetically speaking -- >> hypothetically. >> hypothetically speaking -- >> hypothetically. >> if i say i was there, you know what i mean?

and i saw everything that happened, you know what i mean? and it's, like, that just makes me as guilty, you know? i -- i still get a murder charge. but i didn't kill him. i didn't pull the trigger. >> finally the dam breaks. paul white starts talking. >> i said, "i think he got some cash in there." you know what i mean? so i said, "we can just - we can go in and rob him." but i said, "he probably know who i am. so we going to have to get some masks." we already had those gloves, those cotton gloves that you were talking about. and then we went up to walmart, and they had those little-type ski masks. >> paul white describes a chilling scene of a panicked bob eidman trying to comply with his assailants' demands for money with that notoriously sticky desk drawer, you know, where bob kept his money, instead of in a safe. >> and then he started shaking

and, like, to his drawer, and couldn't get the drawer open. and i was like, "man, just gimme your wallet." so i reached in his pocket and grabbed the wallet. and cleo's like, "man, no, there's more money here." >> there was a lot of finger pointing at each other, trying to point the blame to someone else. >> cleo hines told police he never even got out of the car at bob eidman's office. but paul white wants police to believe that it was always hines who had fired the bullets that killed bob eidman. >> he shot him once. he was like, "man, where's the rest of the money? where the rest of the money?" and he was like, "there is no other money. there is no other money." and he shot him again. i'm like, "man, what the [ bleep ] are you doing?" i said, "man, is he dead?" he was like, "i don't know." shot him again. so i'm like, "man" -- i'm like, "we gotta get rid of this gun." you know what i'm saying? i took it and threw it off the bridge. >> paul white offers to help find the murder weapon, riding along in handcuffs in the backseat of a squad car.

>> we took paul white out of the st. charles county jai. >> going to find the weapon. >> and had him point out the area where he got rid of the gun. >> i would say, like, right in here. >> we searched an extensive area for the gun. was never able to locate it. >> now we have two suspects and two confessions. and with both men pointing the finger at each other, prosecutors are gearing up to put both of them on trial. >> i was sitting in the same room with a person that shot and killed my brother. and that was pretty hard to be calm. >> will bob eidman's family finally learn who murdered him?

one up the power of liquid with tide pods ultra oxi. at the climax of a more than three-year investigation, that at one point involved 37 officers, cops finally learn the details of what was stolen the day of bob eidman's murder. >> how much money was in the wallet? >> it wasn't nothing but like, $300. >> so how much did you get? >> like 150 a piece. >> 150 a piece. >> paul white and cleo both advised they went to the casino after the homicide and lost the $300 almost immediately. >> he went to the casino because that's what he did a lot. >> okay. >> he lost the money.

that was that. >> okay, so he -- >> -- basically did it for nothing. >> right. >> it's hard to think about a man's life being taken for $300. >> he didn't deserve what he got. he was running a business, trying to make a living, and somebody felt that what he had they needed too. and so they took it from him. they could have taken his money and left. they didn't have to kill him. >> as far as any connection between the two men accused of killing bob eidman, and bob's widow, diane, paul white revealed to investigators that he didn't even know who she was. >> do you know a woman named diane? >> no. >> you don't know a woman named diane eidman? >> no. >> with paul white and cleo hines now both charged with bob eidman's murder, it now falls to detective stepp to break the news to diane eidman -- who had long been in his cross hairs. >> i met diane at her place of employment, and i said, "diane, this is over.

we have the individuals and we have the charges on them for killing your husband." >> was she angry at you? >> i don't believe she was angry at me. there was a lot of stress that just came off diane, and you could almost see it leaving her body, and as she was shaking and crying, she was very happy that this was over. >> here some five years after bob eidman's murder, paul white and cleo hines are set to stand trial in this courthouse. two trials, two defendants with two totally different accounts of the crime. >> first up at trial, paul white, who pleaded not guilty to first-degree murder and first-degree robbery. >> really didn't know what to think when i came into trial because i was sitting in the same room with a person that shot and killed my brother. and that was pretty hard. >> the trial for paul white lasted three days, which is actually very short for a murder trial in this county. >> the trial was swift, and so

were the deliberations. the jury needed just two and a half hours before delivering a verdict. paul white, guilty of murder and robbery in the first degree. as for cleo hines, he decided not to put his fate in the hands of a jury. before his trial, he entered what is known as an "alford" plea. >> an alford plea is a plea in the state of missouri where an individual will not say i did it, but there's enough evidence to say i did it. >> with that plea, hines is convicted of a lesser crime than white -- second-degree murder and first-degree robbery. he received two life terms. but while hines' sentence offers the possibility of parole, paul white will never again see the light of day outside a prison. >> paul white was sentenced to life without parole in missouri department of corrections. >> the investigation into bob eidman's murder had cast a shadow of suspicion on his widow, diane.

now, she stood in court and gave her own account of all she had lost. were you there for diane's victim impact statement? >> yes, we were. she said, "i'm going to be alone for the rest of my life. you took my best friend, you took my husband away from me." >> she told the court this in part -- "i looked over my shoulder for five years afraid, never knowing if the people who killed bob were coming after me. or did the police really believe that i killed my husband?" >> i do feel like the system worked. the killers were caught, science prevailed and overwhelmingly provided evidence that got them a conviction. never again can he come to a christmas dinner. never again can we see him for a birthday party. never again could he and my son

talk and have a conversation or a relationship. >> he just loved life. i mean, he was always happy and making jokes, making light of things all the time. we talk about him all the time. it's not like he's gone, he's still here with us. >> deborah: both paul white and cleo hines have tried appealing their convictions but were denied. >> david: hines' first opportunity of parole will be in march of 2034. that's our program for tonight. thanks so much for watching. i'm david muir. >> deborah: and i'm deborah roberts. from all of us here at "20/20" and abc news, good night.
