As we move forward, let's examine real case studies of serial killers from around the world. In this chapter, I have selected some of the most infamous and psychologically complex individuals whose cases have helped shape criminal profiling and public understanding of serial homicide.
Ted Bundy
One of the most infamous serial killers in history, Theodore Robert Bundy, better known as Ted Bundy, has become a chilling symbol of charm masking pure evil. His case is one of the most extensively studied in criminal psychology, not only because of his horrifying crimes but also due to the disturbing duality in his personality: a well-mannered, intelligent, and attractive man who lured dozens of women to their deaths.
