all right. then as to count one, murder, a first-degree felony, how do you plead? guilty, your honor. reporter: 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. so march 10th, 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 run away and be together. reporter: jaclyn thinks chris really believed annie was pregnant. so he persuaded her to meet him 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. reporter: turns out to be a very sloppy crime. the amount of blood.
she came with l.j. 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? pants and shoes and a shirt
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. reporter: in fact, the lab found more than just those two spots of blood. they found several. but, studying the case file, jaclyn noticed that the lab didn t test every spot to see if
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. repor
