Serial Killers & You.Slide2
2What is Multiple Murder?
Some murders are committed only for the offender’s own enjoyment and psychological satisfaction
Many killers have high numbers of victims and their actions are sadistically brutalSlide3
3Mass and Spree Murder
Mass murder: The killing of several people at one location.
Spree murder: The killing of several people at different locations over a period of several days.
These killers typically commit suicide or are killed by the police
.
Two types of mass murderers:
Those who chose specific targets who the killers believe to have caused them stress.
Those who attack targets having no connection with the killer but who belong to groups the killer dislikes.Slide4
4
Most mass murderers are motivated by a hatred that simmers until some specific event provides the flame that brings it to a boil.
Spree killers move from victim to victim in fairly rapid succession.
Spree killing is rare, but spree-killing teams are even rarer and are typically composed of a dominant leader and submissive lover.
Spree and mass murderers have increased steadily in the United States since the middle of the century.

FBI’s three criteria for defining a killer as a serial killer:
Kill in three or more separate events.
At three or more separate locations.
Engage in an emotional cooling off period between murders.
Serial murder: The killing of three or more victims over an extended period of time.Slide6
6The Extent of the Problem
Some empirical evidence suggested that roughly 20% of the murders in the United States yearly were committed by serial killers.
However, other data sources contented that the share of serial killers accounted for no more than 300-400 murders each year.Slide7

13Law Enforcement’s Response to
Serial Killing
The Investigative Support Unit (ISU) of the FBI has developed methods of profiling serial killers and other violent offenders through extensive interviewing and formal psychological testing of incarcerated killers in order to develop a typology based on personality and other offender characteristics
.
Offender profiling is augmented by crime scene analysis, which often tells experienced investigators a lot about the perpetrator’s personality.
May serial murders may occur in diverse police jurisdictions without law enforcement being able to not the connections between them. This problem is known as linkage blindness.Slide14
14
In 1985, the FBI created the Violent Criminal Apprehension Program (VICAP) which was a national clearinghouse that collates information on unsolved violent crimes from different jurisdictions.
Law enforcement now has the ability to link a number of homicides committed in different jurisdictions to a single individual or individuals.

Write a 1 page report answering the question: What makes a killer kill? The focus of this activity is to get you to begin thinking about why homicides occur, what the causes are, actions that are taken, and what makes a killer become a serial killer. You are to use your textbook, chapter 31, as a guide in profiling a criminal. You should also use the Internet, or books you have read in the past/are currently reading, to assist with devising your explanation of your serial killer. There are countless reasons as to why people kill people. Your job is to not solve the crime or evaluate the case proceedings. Your job is to examine and give your best reasoning as to the thinking and motives and actions of a killer. Keep in mind that when a person goes from a single murder to becoming a serial killer, the reasoning behind their actions become more specific and ‘unrealistic’ in nature.
