A serial killer who gets lost a lot and has to ask for directions while covered in blood is not going to last very long. The real profile agreed. Same logic, though it was based on actually having case information. Fishing and Hunting. The choice was that or team sports.
Lets be realistic.
Serial killers are not going to be the most social people in the world. The real profile agreed. For a person to become so violent and antisocial they have had to have a history of disruptive and illegal behavior. Pure logic makes this the appropriate choice. The real profile again concurred.
