* with the murders taking place over more than a month and including a significant period of time between them. While most authorities set a threshold of three murders, others extend it to four or lessen it to two.

Psychological gratification is the usual motive for serial killing, and many serial murders involve sexual contact with the victim. The 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 may have something in common; for example, demographic profile, appearance, gender or race. Often the FBI will focus on a particular pattern serial killers follow. Based on this pattern, this will give key clues into finding the killer along with their motives.

Although a serial killer is a distinct classification that differs from that of a mass murderer, spree killer, or contract killer, there exist conceptual overlaps between them. Some debate exists on the specific criteria for each category, especially with regard to the distinction between spree killers and serial killers.*

Etymology and definition

The English term and concept of ''serial killer'' are commonly attributed to former FBI Special agent Robert Ressler, who used the term ''serial homicide'' in 1974 in a lecture at Police Staff Academy in Bramshill, Hampshire, England, United Kingdom. Author Ann Rule postulates in her 2004 book ''Kiss Me, Kill Me'', that the English-language credit for coining the term goes to LAPD detective Pierce Brooks, who created the Violent Criminal Apprehension Program (ViCAP) system in 1985.

The German term and concept were coined by criminologist Ernst Gennat, who described Peter Kürten as a ' ('serial-murderer') in his article "" (1930). In his book, '' Serial Killers: The Method and Madness of Monsters'' (2004), criminal justice historian Peter Vronsky notes that while Ressler might have coined the English term "serial homicide" within the law in 1974, the terms ''serial murder'' and ''serial murderer'' appear in John Brophy's book ''The Meaning of Murder'' (1966). The Washington, D.C., newspaper '' Evening Star'', in a 1967 review of the book:

Vronsky states that the term ''serial killing'' first entered into broader American popular usage when published in ''The New York Times'' in the spring of 1981, to describe Atlanta serial killer Wayne Williams. Subsequently, throughout the 1980s, the term was used again in the pages of ''The New York Times'', one of the major national news publications of the United States, on 233 occasions. By the end of the 1990s, the use of the term had increased to 2,514 instances in the paper.

When defining serial killers, researchers generally use "three or more murders" as the baseline, considering it sufficient to provide a pattern without being overly restrictive. Independent of the number of murders, they need to have been committed at different times, and are usually committed in different places. The lack of a cooling-off period (a significant break between the murders) marks the difference between a spree killer and a serial killer. The category has, however, been found to be of no real value to law enforcement, because of definitional problems relating to the concept of a "cooling-off period". Cases of extended bouts of sequential killings over periods of weeks or months with no apparent "cooling off period" or "return to normality" have caused some experts to suggest a hybrid category of "spree-serial killer".

In ''Controversial Issues in Criminology'', Fuller and Hickey write that " e element of time involved between murderous acts is primary in the differentiation of serial, mass, and spree murderers", later elaborating that 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.

The Federal Bureau of Investigation (FBI) defines serial killing as "a series of two or more murders, committed as separate events, usually, but not always, by one offender acting alone". In 2005, the FBI hosted a multi-disciplinary symposium in San Antonio, Texas, which brought together 135 experts on serial murder from a variety of fields and specialties with the goal of identifying the commonalities of knowledge regarding serial murder. The group also settled on a definition of serial murder which FBI investigators widely accept as their standard: "The unlawful killing of two or more victims by the same offender(s) in separate events". The definition does not consider the motivation for killing nor define a cooling-off period.

History

Historical criminologists suggest that there have been serial killers throughout history. Some sources suggest that legends such as werewolves and vampires were inspired by medieval serial killers. In Africa, there have been periodic outbreaks of murder by ''Lion'' and ''Leopard men''.

Liu Pengli of China, nephew of the Han Emperor Jing, was made Prince of Jidong in the sixth year of the middle period of Jing's reign (144 BC). According to the Chinese historian Sima Qian, he would "go out on marauding expeditions with 20 or 30 slaves or with young men who were in hiding from the law, murdering people and seizing their belongings for sheer sport". Although many of his subjects knew about these murders, it was not until the 29th year of his reign that the son of one of his victims finally sent a report to the emperor. Eventually, it was discovered that he had murdered at least 100 people. The officials of the court requested that Liu Pengli be executed; however, the emperor could not bear to have his own nephew killed, so Liu Pengli was made a commoner and banished.

In the 9th century (year 257 of the Islamic Calendar), "a strangler from Baghdad was apprehended. He had murdered a number of women and buried them in the house where he was living."

In the 15th century, one of the wealthiest men in Europe and a former companion-in-arms of Joan of Arc, Gilles de Rais, was alleged to have sexually assaulted and killed peasant children, mainly boys, whom he had abducted from the surrounding villages and had taken to his castle. It is estimated that his victims numbered between 140 and 800.

The Hungarian aristocrat Elizabeth Báthory, born into one of the wealthiest families in Transylvania, allegedly tortured and killed as many as 650 girls and young women before her arrest in 1610.

Members of the Thuggee cult in India may have murdered a million people between 1740 and 1840. Thug Behram, a member of the cult, may have murdered as many as 931 victims.

In his 1886 book, ''Psychopathia Sexualis'', psychiatrist Richard von Krafft-Ebing noted a case of a serial murderer in the 1870s, a Frenchman named Eusebius Pieydagnelle who had a sexual obsession with blood and confessed to murdering six people.

The unidentified killer Jack the Ripper, who has been called the first modern serial killer, killed at least five women, and possibly more, in London in 1888. He was the subject of a massive manhunt and investigation by the Metropolitan Police, during which many modern criminal investigation techniques were pioneered. A large team of policemen conducted house-to-house inquiries, forensic material was collected and suspects were identified and traced. Police surgeon Thomas Bond assembled one of the earliest character profiles of the offender.

The Ripper murders also marked an important watershed in the treatment of crime by journalists., While not the first serial killer in history, Jack the Ripper's case was the first to create a worldwide media frenzy. The dramatic murders of financially destitute women in the midst of the wealth of London focused the media's attention on the plight of the urban poor and gained coverage worldwide. Jack the Ripper has also been called the most infamous serial killer of all time, and his legend has spawned hundreds of theories on his real identity and many works of fiction.

H. H. Holmes was one of the first documented modern serial killers in the United States, responsible for the death of at least nine victims in the early 1890s. The case gained notoriety and wide publicity through possibly sensationalized accounts in William Randolph Hearst's newspapers. At the same time in France, Joseph Vacher became known as "The French Ripper" after killing and mutilating 11 women and children. He was executed in 1898 after confessing to his crimes.

The majority of documented serial killers in the 20th century are from the United States.

Late 20th century

The serial killing phenomenon in the United States was especially prominent from 1970 to 2000, which has been described as the "golden age of serial murder." The cause of the spike in serial killings has been attributed to urbanization, which put people in close proximity and offered anonymity.

The number of active serial killers in the country peaked in 1989 and has been steadily trending downward since, coinciding with an overall decrease in crime in the United States since that time. The decline in serial killers has no known single cause but is attributed to a number of factors. Mike Aamodt, emeritus professor at Radford University in Virginia, attributes the decline in number of serial killings to less frequent use of parole, improved forensic technology, and people behaving more cautiously. Causes for the general reduction in violent crime following the 1990s include increased incarceration in the United States, the end of the crack epidemic in the United States, and decreased lead exposure in early childhood.

Characteristics

Some commonly found characteristics of serial killers include the following:
* They may exhibit varying degrees of mental illness or psychopathy, which may contribute to their homicidal behavior.
** For example, someone who is mentally ill may have psychotic breaks that cause them to believe they are another person or are compelled to murder by other entities.
** Psychopathic behavior that is consistent with traits common to some serial killers include sensation seeking, a lack of remorse or guilt, impulsivity, the need for control, and predatory behavior. Psychopaths can seem 'normal' and often quite charming, a state of adaptation that psychiatrist Hervey Cleckley called the " mask of sanity".
* They were often abused—emotionally, physically, or sexually—by a family member.
* Serial killers may be more likely to engage in fetishism, partialism or necrophilia, which are paraphilias that involve a strong tendency to experience the object of erotic interest almost as if it were a physical representation of the symbolized body. Individuals engage in paraphilias which are organized along a continuum; participating in varying levels of fantasy perhaps by focusing on body parts (partialism), symbolic objects which serve as physical extensions of the body (fetishism), or the anatomical physicality of the human body; specifically regarding its inner parts and sexual organs (one example being necrophilia).
* A disproportionate number exhibit one, two, or all three of the Macdonald triad of predictors of future violent behavior:
** Many are fascinated with fire setting.
** They are involved in sadistic activity; especially in children who have not reached sexual maturity, this activity may take the form of torturing animals.
** More than 60 percent, or simply a large proportion, wet their beds beyond the age of 12.
* They were frequently bullied or socially isolated as children. For example, Henry Lee Lucas was ridiculed as a child and later cited the mass rejection by his peers as a cause for his hatred of everyone. Kenneth Bianchi was teased as a child because he urinated in his pants, suffered twitching, and as a teenager was ignored by his peers.
* Some were involved in petty crimes, such as fraud, theft, vandalism, or similar offenses.
* Often, they have trouble staying employed and tend to work in menial jobs. The FBI, however, states, "Serial murderers often seem normal; have families and/or a steady job." Other sources state they often come from unstable families.
* Studies have suggested that serial killers generally have an average or low-average IQ, although they are often described, and perceived, as possessing IQs in the above-average range.Holloway, Lynette
Of Course There Are Black Serial Killers
. ''The Root''. A sample of 202 IQs of serial killers had a median IQ of 89.

There are exceptions to these criteria, however. For example, Harold Shipman was a successful professional (a General Practitioner working for the NHS). He was considered a pillar of the local community; he even won a professional award for a children's asthma clinic and was interviewed by Granada Television's ''World in Action'' on ITV. Dennis Nilsen was an ex-soldier turned civil servant and trade unionist who had no previous criminal record when arrested. Neither was known to have exhibited many of the tell-tale signs. Vlado Taneski, a crime reporter, was a career journalist who was caught after a series of articles he wrote gave clues that he had murdered people. Russell Williams was a successful and respected career Royal Canadian Air Force Colonel who was convicted of murdering two women, along with fetish burglaries and rapes.

Development

Many serial killers have faced similar problems in their childhood development. Hickey's Trauma Control Model explains how early childhood trauma can set the child up for deviant behavior in adulthood; the child's environment (either their parents or society) is the dominant factor determining whether or not the child's behavior escalates into homicidal activity.

Family, or lack thereof, is the most prominent part of a child's development because it is what the child can identify with on a regular basis. "The serial killer is no different from any other individual who is instigated to seek approval from parents, sexual partners, or others." This need for approval is what influences children to attempt to develop social relationships with their family and peers. "The quality of their attachments to parents and other members of the family is critical to how these children relate to and value other members of society."

Wilson and Seaman (1990) conducted a study on incarcerated serial killers, and what they concluded was the most influential factor that contributed to their homicidal activity. Almost all of the serial killers in the study had experienced some sort of environmental problems during their childhood, such as a broken home caused by divorce, or a lack of a parental figure to discipline the child. Nearly half of the serial killers had experienced some type of physical or sexual abuse, and more of them had experienced emotional neglect.

When a parent has a drug or alcohol problem, the attention in the household is on the parents rather than the child. This neglect of the child leads to the lowering of their self-esteem and helps develop a fantasy world in which they are in control. Hickey's Trauma Control Model supports how parental neglect can facilitate deviant behavior, especially if the child sees substance abuse in action. This then leads to disposition (the inability to attach), which can further lead to homicidal behavior, unless the child finds a way to develop substantial relationships and fight the label they receive. If a child receives no support from anyone, then they are unlikely to recover from the traumatic event in a positive way. As stated by E. E. Maccoby, "the family has continued to be seen as a major—perhaps ''the'' major—arena for socialization".

Chromosomal makeup

There have been studies looking into the possibility that an abnormality with one's chromosomes could be the trigger for serial killers. Two serial killers, Bobby Joe Long and Richard Speck, came to attention for reported chromosomal abnormalities. Long had an extra X chromosome. Speck was erroneously reported to have an extra Y chromosome; in fact, his karyotype was performed twice and was normal each time. While attempts have been made to link the XYY karyotype to violence, including serial murder, research has consistently found little or no association between violent criminal behaviour and an extra Y chromosome.

Fantasy

Children who do not have the power to control the mistreatment they suffer sometimes create a new reality to which they can escape. This new reality becomes their fantasy that they have total control of and becomes part of their daily existence. In this fantasy world, their emotional development is guided and maintained. According to Garrison (1996), "the child becomes sociopathic because the normal development of the concepts of right and wrong and empathy towards others is retarded because the child's emotional and social development occurs within his self-centered fantasies. A person can do no wrong in his own world and the pain of others is of no consequence when the purpose of the fantasy world is to satisfy the needs of one person" (Garrison, 1996). Boundaries between fantasy and reality are lost and fantasies turn to dominance, control, sexual conquest, and violence, eventually leading to murder. Fantasy can lead to the first step in the process of a dissociative state, which, in the words of Stephen Giannangelo, "allows the serial killer to leave the stream of consciousness for what is, to him, a better place".

Criminologist Jose Sanchez reports, "the young criminal you see today is more detached from his victim, more ready to hurt or kill. The lack of empathy for their victims among young criminals is just one symptom of a problem that afflicts the whole society." Lorenzo Carcaterra, author of ''Gangster'' (2001), explains how potential criminals are labeled by society, which can then lead to their offspring also developing in the same way through the cycle of violence
