Looks can be deceiving. Somehow, he managed to make a habit of hanging around with people younger than himself. He probably is a very good listener and from what we have heard he is very attentive to details. Both things that would make it easy for him to keep up with things that young people do, say and partake in. Another means for him to present himself online as someone who relates to and understands teenagers and young adults.
I agree. I've gone back and forth so many times on what I think has happened to her and how it went down. He's smarter than he looks. I believe this because of his ability to abduct without witnesses, struggles, screams, dispose of evidence and or bodies. I believe he somehow got AM without much of a struggle. His face doesn't appear to have any injuries in his mugshot or court appearance. And LM would have seen any when they arrested him on other parts of his body. And the lack of evidence (I do believe they have more evidence than we know about but if they had concrete evidence on other charges, wouldn't they have been filed by now?:banghead. Blood, zipties, duct tape, chains, clothing fibres-nothing left behind? How does he get to these athletic girls so easily?
