That case is what got me interested in True crime, as well. There is a very interesting book, written by a forensic psychologist, that includes a full analysis of Scott Peterson as well as Laci Peterson ( and why she would not have seen him for the way he really was) It includes a study of their lives from birth, as well as the details of the crime. You might be interested in it, I couldn't put it down. I don't remember the title, but I'm sure it can be easily found. The author has written several well-know crimebooks.
