rachel newhouse. >> at that point, rex stopped being animated. he stopped being open.ped being talkative. >> it was out of control, right? rex, look at me. it got out of control? rex, tell me what you're thinking. tell me what's going through your head. >> at that point i got concerned because once rex said he wanted an attorney, that means the interview was done. we wouldn't be able to try to recover their bodies or do any follow-up. it was over. and i did not want him to invoke his right to remain silent. so you have to kind of treat him with kid gloves. >> talk to me. look at me. it's not easy. it's not easy. i know that. he shuts me off verbally, but when i touch him, that brings him back into, okay, i'm talking to him. he can feel the touch. but with rex, it still didn't work. >> if you sit there and try to keep beating on me -- >> i'm not beating on you. >> yeah, you are. i'm not going to say nothing. >> i was afraid if i pushed it any further, he would invoke. i made the decision to shut the interrogation down and hopefully be able to resume it the next day. >>
