Her disappearance rocked the community and devastated her parents. Well never know. Her mother made a desperate appeal to trisha on the Jerry Springer show. We love you. Were doing everything to find you. Despite huge Media Coverage and their pleas for answers, none never came. Its like she just vanished into thin air. She was never found.

We were maybe halfway up the road when heather said did you happen to notice that brown van . I said no. Then the van came again slowly. He came by again a third time. Really slow this time looking at us. The hair on the back of her neck started to stand up. The van pulled up beside them. How close . His wheels were on the side of the curb. This was me.

Now, miller contacted the police in halls hometown to arrange for an interview. He initially said, no, you know, he hadnt been over here. Miller had to coax hall to admit being near jessicas house. I said, well, would you remember if, you know, you stopped and offered girls a ride or asked them to get in your van . He said, well, he stops and talks to everybody. After a few questions, miller took a gamble and put a photo of jessica down in front of hall. He immediately flinched. He turned to his right and put his hand up over his face like he didnt want to see the picture. Told me he didnt think hed ever seen that girl.

Which one are you and which ones larry . This would be me. Gary. And larry. In a rare recorded interview obtained by cnn, larry hall recounts a tough start. I know when i was born, my mother told me that i was blue, that i hadnt got enough oxygen to me or something. Identical twin sons, growing up hard. In the hall home, there was little money and lots of problems. Author levin interviewed larry hall. It was a very cluttered household. They were raised with dysfunction. Neighbors say their mother was domineering. Their father drank and sometimes turned violent. He worked at the local cemetery. What was it like growing up next to a cemetery . Was it creepy . No, not at all. Not for me. You know, at 12 years of age, larry and i started working at the cemetery. As he grew older, larry had problems fitting in at school. He was always the backward twin. I was the more dominant outgoing twin. He hung out with what my wife and i and a lot of fellow classmates called the misfits or the stinky crowd. Still, the boys were best friends. And as young men, gary and larry developed an unusual new hobby as civil war reenactors. Met a lot of new friends during that time period and i was able to travel around and meet them at the battlefields either on tours and stuff. It was a lot of fun. Larry was hooked. Even growing mutton chops from his hairline to his jowl. Though the reenactments helped larry make friends, he still struggled with women. What was larry like around young women growing up . Very awkward. Quiet. Backward. Did he ever talk to you about these urges he reportedly says he had urges about women . Oh my gosh, it was absolutely it was out of bounds. I had no idea. Jimmy keen grew up 135 miles away from kankakee, illinois. He didnt know larry hall, and he had no idea that their worlds would someday collide. Third down and five at the 25 yard line. For jimmy keen, life couldnt have been more different. While hall was an awkward outsider, jimmy keen was a star. Especially under the lights on friday nights. We would come out here, the lights would be on. The whole stadium would just be completely full and the crowd would be roaring and it was just a very euphoric, unbelievable high. The friday night games were the biggest rush ive ever had in my life. A gifted athlete, he lettered in two sports. Studied martial arts and inspired fear in everyone he faced. Do you like having people terrified of you just a little bit . Well, in that kind of sport, sure. Thats why they called me the assassin. You were the assassin. Yes. My nickname was the assassin. And the reason why name was the assassin is because i put somebody out at every game ive ever played. Keen wasnt just the hometown hero. He was his fathers namesake. My dad generally sat up here in the corner over here. If i made a spectacular play, he would always give me the you did good son. How much was he sitting in the stands . Every game of my life. He never, ever missed a game or my practices. Does that mean a lot to you . Absolutely. My dad, he was my backbone. Keen was as popular as he was athletic. Youre a lend. Yeah, i mean, theres no doubt. They had posters of me all over town. I mean, everybody knew who i was with my sports ability. So, yeah, i was the most popular guy around. Theres no question. I was voted most popular guy in school. Jimmy seemed to have everything. Except enough money to keep up with the rich kids at school and he only saw one way to get it. He started selling drugs and quickly learned he was good at it. Youre making decent money, you dont think is this a wrong thing that youre doing . So i kept growing into it and growing into it and by the time i was 20 years old, i mean, i was sitting on top of an empire. By keens own account, he was pulling in around 1 million a year. He was addicted. Not to the drugs, but the money. Its hard to walk away from that kind of money, especially a 20yearold. So he didnt. And that single decision would change the rest of jimmy keens life. And bring him face to face with an alleged serial killer. Heartb . Yeah. Try new alka seltzer fruit chews.

License plate, extrahp. Extrahp. By the early 90s, jimmy keen 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 40k parties with volleyball nets, live bands. Wed have literally 1,000 people or more sometimes. I mean, these were gigantic, huge parties. You were the guy women wanted to be with and guys waned 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 didnt stash the drugs here. This is a walkin closet. But there was always a place to hide his fortunes. This was a hidden trap door that you could open. And when you would open it, you have another hidden closet back in here. You can see my old safe is still here. And this was pretty much just my room. For 15 years, keens 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. And to 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 from something wrong, i felt i did something very right to make his world right. But the money never seemed to be enough. And keen couldnt stop watching his back. By the fall of 1996, 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. I said, you know, i am tired of running like this. I said, i really just want this all to end. And it was all an to end, but not the way keen had planned. Just two weeks later i heard the front door rattle and i thought it was just the wind because it was in november and next thing you know, boom. Whole door just blew off the hinges and then they came flying in in a straightfile line with their guns drawn and their black uniforms. Move, well blow your head off. Move, well do this. Just one time. Blah, blah. For jimmy keen, everything is over. Everything stops. It doesnt feel like its real. Keen was ultimately dragged to jail. He pleaded guilty, hoping to minimize his sentence, and at first, federal prosecutor Larry Beaumont was willing to negotiate. Initially we tried to what we call flip him to see if he cowell 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 keen got ten years. It knocked the life out of him and broke his fathers heart. Any hopes and dreams he had had for me at that point in life were gone. He was crushed. He was very crushed. Jimmy keen could not imagine a way out. Nor guess that a man hed never met might someday 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 were on to sting here. This guy portrays this weak, timid person, but, you know, i dont 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. Thats when he opens the door, grabs her. Theres 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. I tied her up, but i cant remember with what. I took her pants off. Hall said he raped her and led her off through the woods. I laid her up against a tree and put a belt around her neck and she stopped breathing. Hall said he strangled jessica from behind so he didnt have to see her face as she died. And that wasnt all. All of the girls looked alike, hall said. I cannot remember all of them. I picked up several girls in other areas, but i cant remember which ones i hurt. Several girls in other areas. There were more victims than just Jessica Roach. Hall said hed also been near the campus of indiana wesleyan university, where Tricia Reitler had disappeared. I was over there because i needed to be with somebody. It was a small Shopping Center, i had a van. Hall said he raped and strangled a girl here, too. Then he identified his victim by pointing to tricias picture. Tricias 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, tricias parents, gary and donna, still suffered. I know with each thing that came in, the urgency was great. And the heartache was great, too. And anticipation and the hope. Halls confession meant the reitlers might at last find their daughter and 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 didnt really happen. He said, it was just my dreams. I said, larry, thats not what you said. You said this happened and you didnt like talking about it because you didnt like the things youd done but you never mentioned it being a dream. But he stuck to his new story. Larry hall was recanting everything. Hey there, i just got my bill, and i see that it includes my fico® credit score.

These days im living with a higher risk of stroke due to afib, a type of irregular heartbeat, not caused by a heart valve problem. At first, i took warfarin, but i wondered, could i up my game . My doctor told me about eliquis. And three Important Reasons to take eliquis instead. One, in a clinical trial, eliquis was proven to reduce the risk of stroke better than warfarin. Two, eliquis had less major bleeding than warfarin. And three. Unlike warfarin, theres no routine blood testing. [ male announcer ] dont stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. While taking eliquis, you may bruise more easily and it may take longer than usual for any bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Ive got three Important Reasons to up my game with eliquis. [ male announcer ] ask your doctor today if eliquis is right for you.
