From all my studies in forensics and criminology, my primary interest is in serial crime – specifically serial murder. One of the most interesting aspects in what we know today about serial killers is that there have been many killing partners.
Typically, whenever we see a serial killer portrayed, we see this lone wolf, solitary, psychopath with sick, twisted fantasies that is driven to search for his victims by his overwhelming compulsion. It has been estimated that approximately 10 to 25 percent of these killers hunt in pairs. That’s actually a very frightening phenomenon.
