A spree killer is someone who commits a criminal act that involves two or more murders in a short time, often in multiple locations. There are different opinions about what durations of time a killing spree may take place in. The United States Bureau of Justice Statistics has spoken of "almost no time break between murders", but some academics consider that a killing spree may last weeks or months, e.g. the case of Andrew Cunanan, who murdered five people over three months.
The general definition of spree murder is two or more murders committed by a person (or people) with no cooling-off period, in contrast to serial murder, where there is a period of time between killings. [1] The U.S. Federal Bureau of Investigation (FBI) has found the category to be of no real value to law enforcement because quantifying a "cooling-off period" is arbitrary. Serial killers commit murders in separate events, at different times. Mass murderers are defined by one incident, with no distinctive period between the murders. [1]
How to distinguish a spree killer from a mass murderer, or a serial killer, is subject to considerable debate, and the terms are not consistently applied even within the academic literature.
The United States Bureau of Justice Statistics has defined a spree killing as "killings at two or more locations with almost no time break between murders". [2] [3]
The Encyclopedia of Crime and Punishment lists five different categories of spree killers and cites Mark O. Barton as an example of the second one. [4] He is also noted alongside mass murderers, such as Patrick Sherrill, in the respective entry about mass murder. [5] In The Anatomy of Motive, John E. Douglas cites Charles Starkweather and Andrew Cunanan (who murdered five people over three months) as examples of spree killers, [6] while Jack Levin calls Starkweather a mass murderer and Cunanan a serial killer. [7] [8]
In Controversial Issues in Criminology, Fuller and Hickey write that "[t]he element of time involved between murderous acts is primary in the differentiation of serial, mass, and spree murderers", later elaborating those spree killers "will engage in the killing acts for days or weeks" while the "methods of murder and types of victims vary". Andrew Cunanan is given as an example of spree killing, while Charles Whitman is mentioned in connection with mass murder and Jeffrey Dahmer with serial killing. [9]
In Serial Murder, Ronald M. Holmes and Stephen T. Holmes defines spree murder as "the killing of three or more people within a 30-day period" and add that killing sprees are "usually accompanied by the commission of another felony." [10] They cite Charles Starkweather and the Beltway Snipers as examples of spree killers. [11] They define serial murder as "the killing of three or more people over a period of more than 30 days, with a significant cooling-off period between the killings." [12] Under this definition, Andrew Cunanan would be categorized as a serial killer and not a spree killer.
In Sexual Homicide, Ressler, Burgess and Douglas gave more emphasis to killings being at more than one location, and less precision about the time span, saying that a single event can last a short or long time, citing Christopher Wilder's seven-week "murder event" or "killing spree". [13]
Douglas wrote that the identity of serial killers is generally unknown until they are caught, and a mass murderer's identity is learned only after they have committed the crime. The identity of the spree killer, on the other hand, usually becomes known by police while the spree is still in progress. [14] [ why? ]
The term rampage killer has also been used sometimes to describe spree killers, [15] especially when a single individual perpetrator:
A rampage involves the (attempted) killing of multiple persons at least partly in public space by a single physically present perpetrator using (potentially) deadly weapons in a single event without any cooling-off period. [16]
A serial killer is a person who murders three or more people, with the killings taking place over a significant period of time in separate events. Their psychological gratification is the motivation for the killings, and many serial murders involve sexual contact with the victims at different points during the murder process. The United States Federal Bureau of Investigation (FBI) states that the motives of serial killers can include anger, thrill-seeking, financial gain, and attention seeking, and killings may be executed as such. The victims tend to have things in common, such as demographic profile, appearance, gender, or race. As a group, serial killers suffer from a variety of personality disorders. Most are often not adjudicated as insane under the law. Although a serial killer is a distinct classification that differs from that of a mass murderer, spree killer, or contract killer, there are overlaps between them.
Mass murder is the violent crime of killing a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. A mass murder typically occurs in a single location where one or more persons kill several others.
Andrew Phillip Cunanan was an American serial killer who murdered five people over three months from April 27 to July 15, 1997. His victims include Italian fashion designer Gianni Versace and Chicago real estate developer Lee Miglin. Cunanan died by suicide on July 23, 1997, eight days after murdering Versace.
Charles Raymond Starkweather was an American spree killer who murdered eleven people in Nebraska and Wyoming between November 1957 and January 1958, when he was nineteen years old. He killed ten of his victims between January 21 and January 29, 1958, the date of his arrest. During his spree in 1958, Starkweather was accompanied by his fourteen-year-old girlfriend, Caril Ann Fugate.
A thrill killing is premeditated or random murder that is motivated by the sheer excitement of the act. While there have been attempts to categorize multiple murders, such as identifying "thrill killing" as a type of "hedonistic mass killing", actual details of events frequently overlap category definitions making attempts at such distinctions problematic.
Caril Ann Fugate is the youngest female in United States history to have been tried and convicted of first-degree murder. She was the adolescent girlfriend of spree killer Charles Starkweather, being just 14 years old when his murders took place in 1958. She was convicted as his accomplice and sentenced to life imprisonment. In 1976, she was paroled after serving 18 years.
The National Center for the Analysis of Violent Crime (NCAVC) is a specialist FBI department. The NCAVC's role is to coordinate investigative and operational support functions, criminological research, and training in order to provide assistance to federal, state, local, and foreign law enforcement agencies investigating unusual or repetitive violent crimes.
Robert Kenneth Ressler was an American FBI agent and author. He played a significant role in the psychological profiling of violent offenders in the 1970s and is often credited with coining the term "serial killer", though the term is a direct translation of the German term Serienmörder coined in 1930 by Berlin investigator Ernst Gennat. After retiring from the FBI, he authored a number of books on serial murders, and often gave lectures on criminology.

Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. The originator of modern profiling was FBI agent Robert Ressler. He defined profiling as the process of identifying all psychological characteristics of an individual and forming a general description of their personality based on an analysis of crimes they have committed.

Jack Levin specializes in research on murder, prejudice and hate, sociology of aging and sociology of conflict at Northeastern University in Boston, Massachusetts. He has interviewed and corresponded with brutal killers, such as the Hillside Strangler and Charles Manson, and other violent criminals: serial killers and rapists, mass murderers, and vicious hatemongers. He is also asked by news and television reports to comment on important occurrences of homicide or hate. Along with interviews, writing material, teaching classes, and research Levin has also given talks about violence or hate to groups including the White House Conference on Hate Crimes, Department of Justice, the Department of Education, OSCE’s Officer for Democratic Institutions and Human Rights and the International Association of Chiefs of Police. Jack Levin has authored and co-authored over 30 books and has written and published over 200 articles.
An angel of mercy or angel of death is a type of criminal offender who is usually employed as a medical practitioner or a caregiver and intentionally harms or kills people under their care. The angel of mercy is often in a position of power and may decide the victim would be better off if they no longer suffered from whatever severe illness is plaguing them. This person then uses their knowledge to kill the victim. In some cases, as time goes on, this behavior escalates to encompass the healthy and the easily treated.
The Behavioral Science Unit (BSU) is the original name of a unit within the Federal Bureau of Investigation's (FBI) Training Division at Quantico, Virginia, formed in response to the rise of sexual assault and homicide in the 1970s. The unit was usurped by the Critical Incident Response Group (CIRG) and renamed the Behavioral Research and Instruction Unit (BRIU) and currently is called the Behavioral Analysis Unit (5) (BAU-5) within the National Center for Analysis of Violent Crime (NCAVC). The BAU-5 currently works on developing research and then using the evidence-based results to provide training and improve consultation in the behavioral sciences—understanding who criminals are, how they think, why they do what they do—for the FBI and law enforcement communities.
The Macdonald triad is a set of three factors, the presence of any two of which are considered to be predictive of, or associated with, violent tendencies, particularly with relation to serial offenses. The triad was first proposed by psychiatrist J. M. Macdonald in "The Threat to Kill", a 1963 article in the American Journal of Psychiatry. Small-scale studies conducted by psychiatrists Daniel Hellman and Nathan Blackman, and then FBI agents John E. Douglas and Robert K. Ressler along with Ann Burgess, claimed substantial evidence for the association of these childhood patterns with later predatory behavior. Although it remains an influential and widely taught hypothesis, subsequent research has generally not validated this line of thinking.
