Sorry just now seeing this. Well if you watch Jeff and how he acts. One thing I can point out right away is how he's looking at the reporter and just talking about the weather likes it's nothing. Then he of course goes on to pretty much say what I have somewhat read about, I mean I broke it down in two looking at this, What made Jeff do what he did, and what kinda of person would be a victim to Jeff. Because I suck at explaining this, a good book that wasn't on my recommenced reading list but I bought because it explains this very well (much better than me). Unmasking the Serial killer. I just don't know, I stayed up one night reading the whole book, it's not really that long of a book sadly, and then came on here and watched this interview and it's an amazing to read the book then watch this. In fact I sent the book and the interview over to my professor. I'm checking for errors and may add some stuff. Blah been looking at my computer all day and I'm not on my own computer right now. I'll also try to send over a some short points I made between the book and the interview. I really got into a note frenzy over watching this interview.
Edit: One point I do remember, Is sometimes that trait that makes someone go out and kill some one (become a serial killer) can be genetic, and the fact his dad said he was having dreams of killing people and being an pyromaniac (one trait for a serial killer.) makes me think some of it is genetic in his case. But I'm not rushing in on that, I don't know terribly enough on Jeffs family past like I am JWG. I know his dad was concerned with the animal killing unlike some killers.
