All serial killers suffer from Antisocial Personality Disorder and appear normal or charming, sometimes referred to as the "mask of sanity." Sometimes there is a sexual element to the murders and they may have a commonality such as gender, occupation, appearances, race, etc.
The term serial killer was coined in the 1970s due to cases such as Ted Bundy and David Berkowitz.
According to an FBI Behavioral Unit study 85% of the world's serial killers are in America. At any given time 20 - 50 unidentified active serial killers are at work continually changing their targets and methods.
Prostitutes, runaways, and others who lead transient and anonymous lives are usually not reported missing promptly and receive little police or media attention, making them excellent targets. Experts speculate on what happens to unsolved cases of murderers. Some may commit suicide, die, be incarcerated, in mental institutions, relocate, or stopped killing; a few turn themselves in.
Experts don't agree on an exact definition of a serial killer but general definitions are based on numbers and patterns: two or more unrelated victims in distinctly separate incidents.
