Overview / Definition

The English word "serial killer" is originallyFBI agent OfRobert K. ResslerBut,Ted Bundy(Theodore Robert Bundy, a serial killer who killed more than 36 women in the United States, executed in 1989) is said to have been proposed in September 1984. Similar meanings such as serial murderer and serial homicide have been used for some time.

There are multiple definitions of serial killers, but according to an FBI report[1], It is summarized in the following common items.

  • Crimes by one person, rarely multiple people
  • There are two or more murder victims
  • The murders are separate and happen at different times
  • Crimes can be committed at regular intervalsMass murder Distinguish between (mass murder) and serial murder

A serial killer is characterized by repeating multiple murders (serially) after a certain period of time (cooling period). If you kill a large number of people at once (1 or more within a day by FBI definition)Mass murderThe criminals are called mass murderers and mass murderers. In addition, anyone who committed murder in more than one place within a short period of timeSpree KillerThis is also distinguished.

It is widely believed by experts that the number of victims meets the definition of a serial killer with at least three murder victims.[4].. Legally, the HR1998 --Protection of Children From Sexual Predators Act of 3494, enacted by the US Congress in 1998.[5]In the statement, "serial killings here are three or more murders in a row, all of which were reasonably committed in the United States and committed by the same criminal or criminals. It is inferred. "

In 2005, the FBI held an interdisciplinary symposium in San Antonio, Texas.[Source required].. This is about serial murderknowledge135 serial killers from different disciplines to identify commonalitiesExpertIt is a collection of. The group also summarized the definition of serial murder, which FBI agents have widely accepted as its standard, as "unlawful killing of two or more victims by the same criminal in separate cases."[Source required].. However, this definition does not take into account the motives for killing and does not define a cooling period.


According to the FBI report, the motive for killing serial killers is often a kind of lust murder to satisfy their desires. However, the direct motive is not limited to sexuality, but also includes anger, profit, thrill and attention.[1].. Robert R. Hazelwood of the FBI Behavioral Sciences motivates serial killers to "satisfy their self-esteem." In other words, it fulfills one's desire by projecting and showing off one's own power to the victim based on "the desire for power, resentment, and the desire for control" toward others, and the criminal act ("self-esteem crime") It means that rape and body damage may be involved as part of this.[6].. Therefore, in many cases, some of the ornaments and bodies worn by the victim are stored as "trophy (souvenir / loot)".

The motives of serial killers are generally divided into the following four categories:[7].. The motives of the individual serial killers may overlap.


Visionary types are oftenMental illnessSymptoms, unrealistic, claiming a different personality, or something else (God or Devil)[8]Instigated by, or claimed to have been permitted[9].. Telepathically communicated(English editionIs that type[10] .

Sexual serial killers have a psychological desire to have absolute control, control, and power over their victims.tortureThere is a desire to cause death while giving pain[14].. The crime is usually committed using a knife or hand that requires close contact with the victim. As the crime continues, the intervals between murders usually become shorter, require more stimulation, or both.[15].


This type of thrilling murder is stimulating and arousing by inflicting pain and fear on the victims. Thrill murders usually do not result in sexual contact and the victims are randomly selected. This type of serial killer can also refrain from murder for a long time. Every time I commit a crimeTrickI think I will not be caught aiming for a perfect crime[16].Robert HansenIs that type[17].Zodiac KillerBut he sent a letter to the newspaper saying, "Murder is better than sex. It's the most thrilling."[18].(English editionIs testified by the victim that he was "enjoyed and excited"[19][20].

The main purpose of this type of serial killer is to project and show power to the victim. This type of serial killer may have been abused in early childhood and may feel helpless or unsatisfactory as an adult. Many of these power and control serial killers commit sexual abuse, with the difference that rape (unlike libido-type serial killers) is not based on libido but a form of domination.[22].Ted BundyCan be said to be this type of serial killer[23].
