reporter: l.j., the guy annie had written that note to. the alleged gang member. the one chris bagshaw said annie had run away with. we had annie s entries that said l.j. we had joanna telling us about l.j. reporter: on that night, said joanna, l.j. and the girl disappeared into the garage. she assumed they were having sex. then when they came out, she saw daniel approach the girl. he asked her if she wanted to [ bleep ] and she laughed. and she was like, no. and he just kind of grabbed her head and just rammed it into the wall. reporter: she said the girl was knocked unconscious. l.j. and another friend named v tried to calm daniel down. and then the three of them carried the girl out to the garage and changed her clothes. tell me about the clothes they changed her into. there was a lot of red. that s what i remember the most. what parts do you remember being red?
away. now there was no hope of her ever coming home. so there s the very worst moment of your life at that point. here they are, three people at the door. they confirmed that it was annie. i think we were in shock. we went into automatic, what do you need from us? tell us what you want. you can have it. look at anything. reporter: veronica told investigators what she learned from annie s on-again/off-again boyfriend chris bagshaw. that annie had run away with a boy named l.j. when you talked with l.j., how did you talk to him? i talked to him once. okay. actually on the phone. okay. reporter: police spoke to chris bagshaw and his father at their home. and when you talked to him on the phone, did he speak with an accent or did you notice anything distinctive about his voice? no. reporter: actually police also had to ask chris where he was. i was with my grandma. okay. and at one point i did walk up to see if my friend can hang out, but he wasn t home. okay.
that he was hiding something and detectives at the time asked for his phone. do you have an idea why we took your phone? for call logs? well, no, that s part of the reason. but there was a message on there that we re kind of interested in. do you know what that message is? reporter: it was a message from chris. the cops might come back to your house. i need you to tell them that annie got a bloody nose so i don t get blamed. he told me about the he said something about the bloody nose. that i actually don t remember seeing. i remember hearing it though. reporter: lab results eventually did show annie s blood was on chris shoes. detectives questioned him about it during a second interview. okay. it would have just been one drop? yeah. reporter: but then his story began to change. where did it drip on your shoe? there was a little bit on the shoelace, and then there was a little bit right here. okay. so those are two separate drops you could see? yeah. repo
the night annie was killed. it s a 1:59 in length. and what really stood out is we see these 25 handoffs. reporter: handoffs, the signal bouncing from tower to tower. but the 25 handoffs were only between these four towers that we were looking at here. reporter: sy created this map of the pings. but the signal strength had to be so similar within those four towers, and a very poor signal at that, that it would cause the handing off that we saw. reporter: eventually they found it, the only spot in town that caused the strange pattern of pings. it was at the jordan river, the very spot where annie was killed. we feel very, very comfortable saying, at 9:01 p.m. on march 10th, the phone was within 100 meters of where we re standing. reporter: of course, a skilled defense attorney could argue just because chris phone was there, didn t mean he was. except for one important detail. it turned out of all the people who could have called chris that night the one who did, at precis
guilty, your honor. a guilty plea. confirming what jaclyn had pieced together over the years of her investigation. and she had a theory about how it all went down. march 10, annie is discussing over the phone what her options are for her baby with chris. and chris is telling her, he s come up with a plan and they can runaway and be together. jaclyn think chris believed annie was pregnant. so he persuaded him to meet her at the river. but. chris has no intent on running away. chris only reason for being there is to kill her. so he just starts beating her until she dies. turns out to be very sloppy, the amount of blood. i feel he betrayed annie more than he betrayed us. annie knew him and annie trusted him. at his sentencing, chris now
