The intertwining of this crime and his field in studying criminal behavior——
did he have these tendencies toward murder and sought to find out everything he could in order to perfect his crime when he had the opportunity? Or did working in this field unhinge something in his mind where he felt he needed to experience it?
Chicken or egg?
But it wouldn’t be necessary to kill FOUR people to experience it. And if it’s true he followed the girls online, and he went to school near them and was a student of UofI in the past, then I think he selected these people purposefully.
When he asked if anyone else was arrested, does that mean someone else is involved, or was this his last psychological trick to play?
