This is a really neat site about the profiling of serial killers and other mass murders. A lot of it is based on information from the FBI, and it has some cool information about the killers, and how detectives can often determine a profile of a potential suspect just by looking at the crime. It is pretty coo, and worth a look, especially if you read Mind Hunter, and found it interesting
Pretty cool website, since reading Mind Hunter i have also read a few other books from Douglas on the art of profiling and this website suggests the book "the anatomy of motive" and i agree its really something to look at if profiling intersets you.
I specifically looked into the Generalized Characteristics of Serial Killers on this website and found it really interesting. Profiling is really interesting to me. Being able to pinpoint exact characteristics of a criminal and even figuring things out about their past without them talking about it, just boggles me. I can see how certain characteristics and the childhood of an individual may lead them to be more prone to antisocial behavior and even possibly become a serial killer. Crazy.
