>> you thought it would be safe and you would be fine? >> exactly. not far at all. i can see the campus. what's going to happen? >> it was getting dark by the time they left the shopping center walking the same route tricia would likely have taken. >> we were maybe halfway up the road when heather turned to me and said, did you happen to notice that brown van? and i said, no. >> then the van passed again, slowly. >> we still were not alarmed. he came by again. >> a third time? >> a third time, yup. really slow this time. looking at us. the hair on the back of our necks started to stand up. >> the van pulled up right up be beside them. >> how close, show me. >> he was, i mean, his wheels were right on the side of the curb. this was me. this was heather and he leaned over and started to say something and at that point we were both like -- run, just run. >> the girls called security,

it but you know you'll keep going and check everything out and recheck everything. >> for over a year, miller scoured local police reports and then, a break. a vehicle reported in a county nearby. the owner? larry hall. >> he had been involved in stopping some girls. those girls were scared. they ran from him. >> in the last six months, hall's van was spotted by more than 11 girls in five different towns close by. including those where jessica lived and where her body was found. now, miller contacted the police in hall's hometown to arrange for an interview. >> he initially said, no. he hadn't been over here. >> miller had to coax hall to admit being near jessica's house. >> i said, well, would you remember if you stopped and offered girls a ride and asked them to get in your van?

he said he stops and talks to everybody. >> after a few questions, miller took a gamble. and he put a photo of jessica down in front of hall. >> he immediately flinched. he turned to his right and he put his hand up over his face like he didn't want to see the picture. he told me he didn't think he had ever seen that girl. >> later, a heartbreaking mystery -- >> there's so little that we can do to find her. i just want to bring her home. >> and the dangerous plan to solve it.

by the early '90s, jimmy keene was on top of the world. his booming business afforded him a lavish lifestyle with large homes, souped up corvettes and an endless supply of women. >> i would have 30 or 40 keg parties with volleyball nets, live bands. we'd have literally a thousand people or more sometimes. these were gigantic, huge parties. >> you were the guy women wanted to be with and device wanted to to be with and guys wanted to be best friends with. >> something like that. >> back then, he owned this 6,000 square foot home. >> right behind that is a golf course. he says he didn't stash the drugs here. >> this is a walk-in closet. >> but there was always a place

to hide his fortunes. >> this was a hidden trap door that you could open and when you open it, you have another hidden closet back in here. you can see my old safe is still here. this was pretty much my ft. knox room. >> for 15 years, keene's empire remained hidden and growing. but as he lived the high life, his father fell on hard times, nearing the brink of financial ruin. >> my dad, to me, was superman. so see him in such a hurt way really killed me. >> so jimmy used his drug fortune to bail his father out. then continued to support him. >> even though it was coming wrong i felt i did something very right to make his world right. >> but the money never seemed to be enough. and keene couldn't stop watching his back. by the fall of 1996, the pressure of life in the fast lane was catching up.

>> i had woke up in the middle of the night and i was laying there wide awake and i thought, i'm tired of running like this. i really just want this all to end. >> and it was all about to end but not the way keene had planned. two weeks later -- >> i heard the front door rattle and i thought it was the wind. it was november. next thing you know, boom, the whole door blew off the hinges and they came flying in a straight file line and guns drawn and black uniforms. we'll blow your head off, move one time -- >> for jimmy keene it was over. >> everything stops and goes in slow motion. you don't even feel like it's real. >> he was ultimately dragged to vail. he pleaded guilty hoping to minimize his sentence and at first, the federal prosecutor larry beaumont was willing to negotiate. >> initially we tried to what we call "flip" him to see if he would give us other drug dealers

at the time. and i think he refused so our reaction was to make sure he gets the maximum penalty. >> beaumont got his way and keene got ten years. it knocked the life out of him and broke his father's heart. >> any hopes and dreams he had had for me at that point in life, were gone. he was crushed. i mean, he was very crushed. >> jimmy couldn't imagine a way out. nor guess that a man he had never met might some day provide him one. november 1994, wabash, indiana. it had been two weeks since larry hall recoiled from a photo of jessica roach. and investigator gary miller had a gut instinct. >> i really think we're on to something. he portrays this weak, timid person, but, you know, i don't

think he truly is. >> miller thought hall was vicious and as the investigation unfolded, miller also thought he knew how hall abducted jessica roach. >> when he first seen her, she was riding from toward the house going down this way. >> hall followed and stopped to talk. jessica got scared and backed away. >> that's when he opens the door, grabs her and there's a physical confrontation where he overpowers her. put her in his van and left, probably going up this road right past her house. >> in an interview in the wabash police station, hall surprised investigators by explaining what happened next. hall said he raped her and led her off through the woods.

hall said he strangled jessica from behind so he didn't have to see her face as she died. and that wasn't all. several girls in other areas. there were more victims than just jessica roach. hall said he'd also been near the campus of indiana wesleyan university where tricia reitler had disappeared. hall said he raped and strangled a girl here, too. and then he identified his victim, by pointing to tricia's picture.

tricia's disappearance had remained a mystery for 18 months. >> we were just kind of sitting on the sidelines waiting for information to come in. >> with little evidence and local police insisting on another suspect, tricia's parents, garry and donna still suffered. >> with each thing that came in the urgency was great. and the heartache was great, too. and the anticipation and the hope. >> hall's confession met the reitler's might at least find their daughter. and that gary miller had found the killer of jessica roach. but the next day, hall changed his story. >> as i was talking to him he said, i was just telling you about my dreams. that didn't really happen. he said, it was just my dreams. i said, larry, that's not what you said. you said it happened and you didn't like talking about it because you didn't like the things you had done but you never mentioned it being a dream. >> but he stuck to his new story.

larry hall confessed to killing jessica roach, tricia reitler and two other women and took it all back claiming it was just his imagination. >> reporter: but investigator gary miller had other evidence, like the witness who drove by this corn field the night of jessica's murder. >> that person testified he was absolutely sure that when he went by here on that night there was a van and a guy coming from the corn field and getting in his van. >> reporter: a search of hall's house and van revealed heed been casing out small college towns and keeping suspicious notes. seen joggers and bikers, many alone.

check colleges, parks, seen some prospects. hall also made lists for the hardware store. and hall wrote himself troubling instructions. amongst hall's things, investigators found newspaper clippings about roach and reitler, possessions from other missing girls and pornographic pictures that hall had altered? in the pictures he had drawn a rope or belt around the neck of one on the left side, he had drawn blood. >> reporter: hall insisted it was staged to make a play for attention to feel important to police. >> i have put a punch of stuff

in that van i drove around because i knew they would eventually search my van and find them. >> reporter: during larry's trial, his twin brother gary tried to provide him an alibi. still federal prosecutor larry beaumont got hall convicted of kidnapping jessica roach. >> the federal system, if you are guilty of a kidnapping if the kidnapping resulted in a death under the sentencing guidelines it is mandatory life term. >> reporter: the jessica roach case was over but the disappearance of tricia reitler remained unsolved and her parents would not stop looking. >> we walked the sides of the roads, the river beds. we looked under the culverts. we ended up going to crack houses because somebody had a lead. >> if you see something on the side of the road, a garbage bag, whatever. it is like could that be her? it was a horrendous crime to lose your daughter and never

find out what the heck happened to her. >> reporter: larry beaumont kept looking, too. >> i made arrangements on a couple of occasions to go out and look for the body. >> reporter: beaumont called in specialized military and law enforcement units to search. >> we weren't able to find her. rather than give up, it occurred to me that obviously larry hall knew. >> reporter: beaumont needed answers and turned to an unlikely source to get him. he needed someone to befriend larry hall, someone charismatic and on the inside. larry beaumont needed jimmy keene. beaumont had sent both keene and hall to prison. now he hatched a risky plan that would bring them together. keene was ten months in to his sentence when beaumont brought him in to talk. >> scared me. i thought this was some trick. >> reporter: keene watched

nervously as he pushed a folder across the table. >> first thing i seen was the picture of a mutilated dead girl and i flipped to the next page and there was a different mutilated dead girl. >> and there was a portrait of tricia reitler. at that moment i looked at him and he said we need you to help with this case. >> reporter: he wanted him to go undercover from a low-security lockup to a dangerous prison and befriend alleged serial killer larry hall. >> he said if you can get solid confessions from him and locate the bodies that are still missing we are willing to completely wash your record. >> reporter: keene's mission, to learn where tricia reitler was buried in the purpose of the operation was to find the body. >> reporter: beaumont made it clear, no body, no early release. keene would have to serve the rest of his ten-year sentence. but beaumont believed keene could do it.

>> he is smart, articulate, not afraid and i knew he wanted to get out. >> reporter: for keene it was a chance at redemption, to restore his family name and says author hillel levin to get his life on track. >> this deal was a way for him to get home and a way for him to do good, to kind of take this bad thing he had done and to somehow turn it inside out and make it something that would solve a crime. >> reporter: but it wouldn't be easy. fair to say he was risking his life. he could have been killed. >> it was dangerous, absolutely. it was highly risky. these people in those type of places don't have anything better to do than to try to hurt and kill you, too. keene was unsure but a phone call home put his doubts to rest. keene's step mother said his father had suffered a stroke. >> she said he's in really bad shape. we wish you were here.

this is terrible you are in the spot where you are in right now because we could lose him. >> reporter: he needed to get home fast and there was only one way to make that happen. he had to face an alleged serial killer first. >> i decide, you know what, however bizarre or how far out or whatever this mission that beaumont wants me to go on i'm going to do it. with crest 3d white professional effects whitestrips. it penetrates below the enamel surface to whiten as well as a $500 dentist treatment. the secret's in the strip. crest 3d white professional effects whitestrips. life opens up when you do. usa prime credit... this peggy... hi, i'm cashing in my points... peggy? no more points - coupons now. coupons? coupons. coupons? next, you convert coupons to tokens. tokens? then you trade tokens for credits. and then i get the cash? then you call back. bye bye.

driving up to the prison in springfield, missouri, jimmy keene didn't know if he had made the best or worst decision of his life. >> i started to get cold feet. i looked at the u.s. marshal and i said, listen, how do we know if beaumont will live up to his word. they all assured me he would. i said i'm not sure i can do this. >> reporter: there was no turning back and he needed to prepare. agents had warned him to be careful. >> we don't want you to approach him for at least six months because he's a cagey individual. if he senses one thing wrong he goes in to a shell like a turtle and you will never get him back out once he is in. >> reporter: keene didn't have time to wait. he needed to get him to his ailing father. so hours after becoming a springfield inmate he spotted larry hall and made his first

move. >> i made it a point for us to bump shoulders together. as we gently bumped shoulders together, i said, excuse me. i said, listen, i'm new here you wouldn't happen to know where the library was, would you. >> keene offered to show him the way. >> i slapped him on the shoulder and said i appreciate that from a cool guy like you. >> over the next week keene watched hall's every move, from his cell across the hall. >> i walked up to him and said this is where i am at and i said are you in this area and he said, yes i am right there. i said that is great. you are right by me. i told you were a cool guy and i am glad you are by me and this and that and that is when he offered if i wanted to have breakfast with him and his friends. >> reporter: keene was making progress, slowly gaining hall's trust but life at springfield

was complicated and dangerous. so keene figured out a way to use violence to his advantage. it was a saturday night and hall was in the tv room mesmerized by an episode of "america's most wanted" about serial killers. suddenly another inmate approached the tv. >> you could tell this guy had been in a long time. he was a big, buff guy. he just walked up to the tv and looked at everybody in there and decided to turn the channel. and he turned it. i found this very interesting. larry looked at me and very quietly mumbled under his breath, hey, i was watching that show. >> reporter: keene leaped in to action and knocked the guy out. >> i nailed him with an upper cut and kicked him through three rows of chairs. he was beat up and had to go to the hospital. and they took me and put me in the hole. >> reporter: it was worth it and a breakthrough at hall? he looked at me as a guy that he

could look at and say he thinks i'm cool, coming from him that is a compliment and he is able to protect me. >> reporter: now keene had hall's trust and had him talking. one night, in hall's cell, he told keene the truth about what happened to tricia reitler. but what hall told keene was different from what some investigators believed. it was his story along with some evidence that created a road map i wanted to try to follow to figure out what happened to tricia reitler. tricia would have left this supermarket parking lot, walking just a couple of blocks back to campus. somewhere along this road, hall told keene he got tricia in to

his van. when she fought off his advances, he says he choked her to keep her quiet. hall told keene he blacked out and when he woke up, tricia was naked and lifeless. days after her disappearance, investigators found her blood-soaked clothes here, just one block from the supermarket. hall's own notes indicate what might have happened next exactly one week after tricia's disappearance hall wrote, cut out stained carpet, vacuumed van thoroughly, buy new hacksaw blades, clean all tools. along with his notes was this address, 700 west slocum. where in the woods, half way between marion and wabash and it is possible that somewhere, out here that tricia reitler is

buried. >> he says so he got some lime together a shovel and lantern and he drove her to the woods and buried her in the woods. >> reporter: he admitted to you he buried her in the woods. >> several times he admitted that, yes. i basically made him feel like it was okay for me to tell the secret. >> reporter: keene needed a secret that would set him free, the exact location of tricia's body. weeks later he thought he nailed it when he found hall hovered over a map in the prison workshop. >> it was a map with red dots over indiana, illinois, wisconsin and he covered it up really fast. >> reporter: lined up at the edge of the map are a dozen wooden falcons. >> i said this is pretty cool, did you make these and he said yeah, i make them. it is really cool, isn't it, they watch over the dead. >> reporter: falcons to watch over the dead and a map marked

with dots. it was the information keene thought would surely lead in the exact location of tricia's body. >> in that moment, did you think this is my ticket to freedom? >> i did because i thought this is it. i have solid confessions out of him. we know specific details. we know how he's done it now. >> reporter: keene believed he had his answer that he would soon be free. that he was done forever with larry hall. so that night, at lockdown, keene decided to tell hall what he really thought. >> i told him he was a [ bleep ] sicko. i told him he's insane. i told him you are one of the most despicable human life forms on the planet. at this point he slid away and was terrified of me at moments and he said beaumont sent you, didn't he. beaumont sent you, didn't he. >> reporter: keene had blown his cover and his outburst landed

him in solitary confinement. >> it took some time that we found out that jimmy was put in the hole so he wasn't able to communicate with anyone on the outside. >> reporter: by then hall's map and the falcons had disappeared. worst of all as keene was let out of springfield prison to face larry beaumont he didn't know if what he had learned was enough to set him free. during his months in [ female announcer ] find yourself sometimes cleaning up after your dishcloth? bounty extra soft can help. in this lab test bounty extra soft leaves this surface three times cleaner than a dishcloth. super clean. super soft. bounty extra soft. in the pink pack. did you hear sam... ...got promoted to director? so 12 seconds ago. we should get him a present. thanks for the gift basket. you're welcome. you're welcome. did you see hr just sent out new... ...office rules? cause you're currently in violation of 6 of them. oh yeah, baby? ...and 7. did you guys hear that fred is leaving? so 30 seconds ago.

during his months in springfield, jimmy keene got larry hall to provide details about several murders hall was suspected of committing including tricia reitler's. but keene hasn't met the original requirements. >> i told him if we didn't find the body, no body no credit. >> reporter: sitting in his prison cell jimmy keene desperately hoped he had done enough. >> are they going to be fair and give me what is justifiably

right on this or say here's six months. it was a crap shoot. >> reporter: without a location for reitler's body, beaumont had a decision to make. >> i made the decision to take a polygraph test to verify what he was telling us was true and he did make a legitimate effort to do what we sent him to do. >> reporter: to beaumont urged the federal judge to give him credit for time served. jimmy keene became a free man and returned home to his aging father. what did you feel like when you were finally released? >> i was happy as could be. it was a bizarre roller coaster i went on. it was redemption at its best. >> reporter: keene had five more good years to be with his father before big jim passed away. >> we both realized once i got out there that there is a better world than just always in a constant dash to make money.

it was more like, look, let's just enjoy each other while we are alive here, you know? >> reporter: it was closure for keene but not for the families of the alleged victims of larry hall. for years there was no progress and no relief for people like donna and gary reitler. >> as a parent, there's a part they have let her down and that you want to find her and bring her home and you can't. i mean we've done pretty much physically everything we can to find her and there's somebody out there that holds that one answer for us. >> reporter: beaumont, too, felt he had done all he could and that the pursuit of larry hall was over. >> there wasn't going to be no further prosecution from the federal perspective. he's already serving life in prison. he was done. >> reporter: once again, larry hall had slipped off the radar and it could have easily remained that way, except for jimmy keene.

first keene's story of strange redemption was featured in a "playboy" article and then a book written by keene and levin. >> once we were able to write about what keene went through things happened. >> reporter: it refocused attention on larry hall. helped to reopen cold cases and put pressure on his twin brother gary. now gary stopped defending larry and started talking. >> larry just like jimmy keene calls him, and he is, he's a baby killer. >> reporter: you think your brother is a baby killer? >> i don't have no doubt in my mind. >> reporter: do you think your brother killed more than jessica roach? >> yes. >> reporter: do you think your brother killed tricia reitler. >> yes. >> reporter: rayna ricin, michelle dewey. >> yes. >> reporter: as gary talked more

openly, detectives approached him asking for help. >> i went with the indianapolis detectives down to try to get my brother to confess. he made me leave the room. he did, in fact, confess on tape to 15 serial murders. >> reporter: larry later retracted again. while he can't ever seem to stick to one story, he does sometimes seem to have regrets. >> reporter: larry hall refused our request for an interview. he's never been charged with crimes against anyone other than jessica roach. but keene's story has caused officials across the country to take another look at hall. november 2010, the investigators

interviewed mr. hall at a federal prison in north carolina. >> in that interview, hall admitted to murdering laurie and provided clues where to find her body. >> there are multiple agencies looking in to him and disappearances. >> he may have had more victims than ever imagined. >> we understand it is more extensive than we ever thought. not 20 but maybe 30 to 40 in terms of the victims. >> reporter: that leaves 30 or 40 families still awaiting answers, which is why, says levin it is critical that serial investigations do not stop. 18 years after tricia reitler vanished her father now believes larry hall knows where to find her. >> i think if larry knew what we go through on a daily basis, wondering where she is, and

wondering what happened. i don't think he would have any choice to confess and let us know where she is buried. >> reporter: donna is not as sure. >> he confessed and recanted. he confessed, he recanted without a body, it's just another possibility. more than anything else they just want their daughter back. >> to have a place to lay her to rest. just to be able to sit and talk to her. >> reporter: as for jimmy keene, his truth is stranger than fiction. he's gone from football standout to drug dealer to undercover operative. and now to screen star. with his story in development as a hollywood film. still, says keene, he thinks of
