I also don’t think he woke up & planned on killing MT that Wed. He might not have abducted & murdered a stranger before, but I believe he has mistreated women in his past. Behavior like this doesn’t begin out of the blue at 24.
In his case, that would mean that he had been somewhat respectful to women for 2 decades and then *Boom* kidnaps a stranger, kills her (possibility of SA). He might not have abducted a female before, but I bet he’s tried several times.
IMHO, it’s highly likely he has Sexually Assaulted females before now, either a stranger, ex- g/f, or relative. Not saying it did happen just that I think it is highly likely. IMHO his behavior escalated to this point, where he felt confident enough to take a stranger and kill her. I don’t think he has control over his emotions, but I do think it’s sexually motivated and he’s fantasized about abduction. I think he possibly kept himself prepared in case he actually acted out his fantasy & did it.
He’s only 5’6 and 130 lbs, which means he had to choose someone smaller—like MT. He probably thought she was pretty & saw her vulnerability because she was in an isolated area. If he just wanted to chat, he probably wouldn’t have picked such an isolated area (out of view of stores & their cameras), but instead would have stopped circling & chosen a more convenient place to join in the run.
