"He and another man, John Douglas, were the first individuals who actually conducted research on serial killers," Hazelwood says. Roy Hazelwood, who worked with Ressler at the FBI for more than 20 years, says that was far from his only contribution. Soon after joining the FBI in 1970, Ressler had the Bureau convinced of the legitimacy of criminal profiling. So Ressler thought that by figuring out how - and why - those criminals worked, maybe the next time, police could better figure out who they were looking for. By then, he had already retired from an FBI career that was both long and influential.īefore he joined the bureau, Ressler's time in military and civilian law enforcement had piqued his curiosity about crimes that were tough to understand: violent, sometimes sexual and always seemingly irrational. "There are people that are pretty good at this, and I would consider myself one of them, certainly," Ressler said in an NPR interview in 1997. The FBI investigator actually wrote the book on criminology, during a career spent researching serial killers and other violent offenders.

There have been 220,000 unsolved murders in the U.S. Thrill seekers are serial killers that see outsmarting the law as some sort of amusement. The four main types of serial killers based by the type of crime they commit are as follows: thrill seekers, mission-oriented, visionary killers, and power/control seekers. Those who've studied serial killers believe that many are at least partly motivated by the attention and fame that mass media can provide mass murderers. Serial killers often are loners who fear all relationships and seek to control, to destroy other people to eliminate the possibility of another humiliating rejection. As a consequence of that trauma or separation, scientists believe, they learned to suppress empathy or suffered damage to the areas of the brain that control emotional impulses. Research shows that certain genes can predispose people to violence. Many serial killers experience childhood trauma or early separation from their mothers. They never learn the appropriate responses to trauma, and never develop other emotions, which is why they find it difficult to empathize with others. Trauma is the single recurring theme in the biographies of most killers As a consequence of this trauma, they suppress their emotional response. Many serial killers are survivors of early childhood trauma of some kind – physical or sexual abuse, family dysfunction, emotionally distant or absent parents.
The book explores how our understandings of serial killers – called “monsters” before the advent of modern psychology – have changed over time, and considers answers to a difficult question: what, exactly, “makes” a serial killer? Peter Vronsky is t he author of Sons of Cain: A History of Serial Killers from Stone Age to the Present, a book that explores why some people become killers, and others don’t. Are serial killers a product of nature (genetics) or nurture (environmental factors)? One of the oldest questions in criminology – and, for that matter, philosophy, law, theology – is whether criminals are born or made.
