The serial killer profile emerged as a dominant framework in criminal investigations and popular media for understanding cases involving multiple murders.1 In the cases examined on this page, the framework was frequently applied to explain complex criminal operations as the product of individual pathology rather than organized networks.

Coinage and Earlier Usage

The first documented use of the phrase "serial killer" is credited to the Berlin detective Ernst Gennat, who in 1930 wrote about the Düsseldorf child murderer Peter Kürten, setting aside press descriptions of the killer in favor of the plain term Serienmörder.2 The earliest English citation in the Oxford English Dictionary is a 1961 essay by Siegfried Kracauer on Fritz Lang's film M.2 The British writer John Brophy applied the term to Jack the Ripper in The Meaning of Murder, published in 1966.3

Robert Ressler, an agent of the Federal Bureau of Investigation's Behavioral Science Unit who was long credited with coining the English term, wrote in his 1992 memoir Whoever Fights Monsters that he heard the phrase "crimes in series" from a participant at a weeklong conference at a British police academy in the early 1970s, and that after returning to Quantico he began using "serial killer" in his own lectures.4 Later research traced the phrase to earlier sources.4

The Behavioral Science Unit and the 1983 Hearing

On July 12, 1983, the Subcommittee on Juvenile Justice of the Senate Judiciary Committee, chaired by Arlen Specter, took testimony in a hearing titled Serial Murders. Specter's opening statement described "a rising pattern of serial murders which suggest no justification and no explanation."1 The witnesses were the author Ann Rule, a former policewoman who had written extensively on serial murder, John Walsh, the father of a murder victim, Pierce Brooks, a Los Angeles police veteran who was the originator of the Violent Criminal Apprehension Program, and Roger L. DePue, unit chief of the Behavioral Science Unit at the FBI Academy.5 The hearing summary records the witnesses' view that the serial murderer kills victims with similar profiles, using similar methods, in sequence and often in widely separated geographic areas.5

The Bureau's written answers to the subcommittee, forwarded under the signature of FBI Director William H. Webster, stated that the FBI believed a system was needed to track and analyze serial murders. The same answers reported that information from law enforcement agencies indicated serial murders were increasing, and described a 1978 research project in which the Behavioral Science Unit and selected consultants set out to analyze the crimes and personalities of "the most notorious serial killers and mass murderers incarcerated in the United States."6

DePue's prepared statement gave the planned number of interviews with convicted serial murderers as 35 to 50, and in oral testimony he said the unit had interviewed 35 of them.7 He testified that the unit's profiling program began in the early 1970s as a spinoff of a course at the National Academy, where officers such as Pierce Brooks discussed unsolved cases.7

The Figure of Thirty-Five

A January 1984 article in the St. Louis Post-Dispatch credited Robert O. Heck, a program manager in Washington's Office of Juvenile Justice, with an estimate that at least thirty-five serial murderers were at large. Heck said he had reached the figure through a survey of unidentified dead bodies reported by medical examiners in cities of 300,000 or more.8

VICAP

Brooks's testimony begins on page 29 of the hearing record, and his paper "VI-CAP: The Violent Criminal Apprehension Program" is printed at page 37.9 A progress report by J. B. Howlett, K. A. Hanfland and R. K. Ressler, covering the system's first six months, describes its case criteria as all solved or unsolved homicides, missing-person cases where homicide is suspected, and unidentified bodies where the manner of death is suspected to be homicide. Its staff looked for patterns in criminal method, victimology, physical evidence, suspect description and suspect behavior.10

Jenkins and the Construction of the Problem

In Using Murder (1994), Philip Jenkins argued that popular fears and stereotypes had vastly exaggerated the scale of multiple homicide. He placed the issue in public debate, where concern over serial murder served the interests of agencies and of groups who used the subject in arguments over gender, race and sexual orientation.11

The 2005 Symposium Definition

In 2005 the FBI convened a multidisciplinary symposium in San Antonio, Texas. Its monograph defined serial murder as "the unlawful killing of two or more victims by the same offender(s) in separate events."12 The symposium also set aside several popular beliefs, among them that serial killers are "all dysfunctional loners" and that they "all travel and operate interstate."12

The Crime Classification Manual

John E. Douglas, Ann W. Burgess, Allen G. Burgess and Robert Ressler published the Crime Classification Manual in 1992 as a standard system for investigating and classifying violent crimes, drawn from the FBI's National Center for the Analysis of Violent Crime.13

The Lone Killer Narrative

This pattern repeated across multiple investigations. Dean Corll was nicknamed "The Candyman Killer," and the motive behind his murders was attributed to his modus operandi as a serial killer, which is to say that motive was sought in the psychology of a single individual rather than in the organizations he claimed to belong to. Elmer Wayne Henley and David Owen Brooks each stated independently that Corll claimed to belong to an organization based in Dallas that bought, sold and murdered boys. The writer S. Dovey wrote that investigators treated these statements as fabrications and focused solely on Corll's individual pathology.14

John Wayne Gacy was convicted of thirty-three murders and sentenced to death. The writer S. Dovey wrote that the official account attributed all of the murders to his individual psychological profile.15 The Illinois Supreme Court's 1984 opinion in the appeal records a jury verdict on thirty-three counts, death sentences on twelve murders committed after the death penalty statute took effect, and natural life terms on the remaining murder counts. The opinion also records that in the course of the investigation Gacy admitted killing approximately thirty people, and that 29 bodies were recovered from the crawl space and surrounding ground at his home.16 The prosecuting attorney who secured his conviction, Terry Sullivan, published an authoritative accounting called The Killer Clown, which entered the annals of true crime in 1983.17

At trial, David Cram testified that Gacy had him dig trenches in the crawl space, purportedly for drainage, and had him spread lime throughout it. Michael Rossi testified that he helped dig the trenches and supervised newer employees who dug them, and that Gacy had sold him a car previously owned by one of the victims.18 According to the writer S. Dovey, Gacy's own claims that Phillip Paske, Cram and Rossi were involved in burying bodies, and that he worked for a crime syndicate, did not alter the serial killer framework. Dovey also wrote that the similarities between the Gacy and Corll cases are striking: both used handcuff tricks and wooden torture boards, both buried victims in mass graves beneath their properties, and both lived with teenage accomplices who claimed they worked for larger organizations.15

Oakland County and the Profile Trap

ClickOnDetroit's timeline of the Oakland County Child Killer case describes a serial killer who abducted and held four children between February 1976 and March 1977.19 The writer S. Dovey wrote that the task force shifted its focus toward the psychological profile of an elusive individual, and that the investigation gained notoriety through the assumption that a serial killer driven by a modus operandi defined by a psychological profile was responsible for the murders.20

Gregory Greene was arrested in January 1977 on child sexual assault charges and told investigators that Christopher Busch had killed one of the four boys. Busch and Greene both passed polygraph examinations. Greene was convicted and sentenced to life in prison, and Busch received probation on the charges against him.19

Dovey wrote that the two prime suspects were Kent Gilbert Schultz and Busch, both convicted pedophiles tied to Francis Shelden, and that both were cleared as suspects on polygraph tests. In Dovey's account, Busch died of a reported suicide one day before the task force was dissolved, the case went cold, and the serial killer narrative remained intact despite evidence pointing toward organized child pornography networks financed by Shelden.20

Dutroux and Political Function

In the Marc Dutroux case, the serial killer narrative served a specific political function. In January 1998 Regina Louf gave up her anonymity as witness X1, in part to protest the stalling of the inquiry, amid a press campaign against her.21 The writer S. Dovey wrote that the X-witness accounts were all dismissed as a hoax, that on these grounds the witnesses were prevented from testifying at the trials of Marc Dutroux and Jean-Michel Nihoul, and that X1 was publicly discredited as a fantasist while a media narrative was built around Dutroux as a lone serial killer.22 According to Dovey, this framing allowed the investigation to focus on an individual perpetrator rather than on the network of associates and clients that survivors had described.

The Zembla broadcast of March 11, 2004 stated that Dutroux's lawyer asked that X1 be heard at the trial in Arlon.23 On January 30, 1998, magistrates charged with verifying the witnesses' statements in the districts of Antwerp, Brussels, Ghent and Neufchâteau held a press conference at which they stated that no element of proof supported the statements, which also contained many contradictions.24 The journalist Roland Planchar wrote in 2004 that a DNA analysis reported on March 17, 2000 did not match Nihoul or any known suspect in the Dutroux case, against an account by X1 that she had been present when Nihoul raped a teenage victim.25 Planchar also wrote that for some people, challenging the X witnesses was a way of opposing the idea of a large network around Dutroux, a position the most extreme critics labeled "revisionism," including the lawyer for two of the victims' families. For others, he wrote, the aim was a return to proven facts.26

The Belgian Chamber of Representatives inquiry into the conduct of the police and judicial investigations in the Dutroux-Nihoul case issued a first report on April 14, 1997. It stated that the commission had exposed the causes of the failure of the investigation but not yet the reasons, and could not exclude that an eventual protection was one of them.27 The commission's supplementary report of February 16, 1998 stated as its general conclusion that there were indications that both Dutroux and Nihoul, separately or together, had engaged in polycriminal activity (fraud, drug trafficking, abduction and rape of children followed by murders, trafficking in human beings, car trafficking) and that the networks they set up had benefited at various levels from an indirect protection arising from individual or collective erosion of the norm or corrupt conduct. The same conclusion stated that the commission had found no indication that these criminal circles enjoyed, within the police, the magistracy, the administration or the political world, protection that could by itself explain the failures, delays and anomalies of the investigations, and that the serious gaps arose chiefly from professional failings and structural defects of the criminal justice system.28 On the Nihoul circle in particular, the report stated that it had not acquired proof that Nihoul and Annie Bouty had enjoyed protection in the fraud files, and that Nihoul's claim of protection by a Brussels investigating judge was found to be untrue.29

Judge Jean-Marc Connerotte, who had appealed for victims of a suspected child sex trafficking network to come forward, was replaced as overseeing magistrate after eating a plate of spaghetti at a public function, sparking protests by 300,000 Belgians, according to the writer S. Dovey.30 Dovey also wrote that Marc Dutroux was not a serial killer in any of the definitions provided by behavioral scientists, that he was a profit-driven and marginal figure on the periphery of a child sex trafficking network, and that the serial killer label obscured networks involving politicians, magistrates and royalty.30

Atlanta and the Single-Offender Verdict

In Atlanta, a 1982 jury convicted Wayne Williams of the murders of two men, and the state introduced evidence of ten other alleged murders to help establish his identity as the perpetrator of the two.31 The Supreme Court of Georgia affirmed the convictions on December 5, 1983, and addressed the fiber comparisons drawn from the bodies of twelve victims.31 In 1985 Murray Kempton, reviewing the CBS film The Atlanta Child Murders, wrote that official Atlanta had announced that the violent deaths of twenty-nine persons, most of them young boys, "had been solved with the conviction of Wayne Williams for the murder of two of them."32

Zebra and the Cult Account

Clark Howard's 1979 book Zebra, as summarized by Kirkus Reviews, attributed a series of random San Francisco killings to five men of a squad called the Death Angels, which the book said was sponsored by the Nation of Islam.33 Maury Terry's The Ultimate Evil (1987) argued that the Son of Sam shootings in New York were directed by a Yonkers-based cult.34

The Official Position

In January 1992 Kenneth V. Lanning, a supervisory special agent in the Behavioral Science Unit, published an FBI investigator's guide to allegations of "ritual" child abuse. Lanning wrote that "in none of the cases of which I am aware has any evidence of a well-organized satanic cult been found." He wrote that "it is simply too difficult for that many people to commit so many horrendous crimes as part of an organized conspiracy," and that "the more people involved in the crime, the harder it is to get away with it." He described the Jack the Ripper murders as the work of "one disorganized but lucky individual," and he treated the appeal of the conspiracy theory as twofold, offering a simple explanation for a complex problem and a popular account that one bizarre individual could not be responsible.35

Two Frames

The record above contains two frames. In the first, each case is attributed to one offender: Williams, convicted of two of the Atlanta murders; Gacy, convicted of thirty-three; Corll, whose crimes the record attributes to one man's pathology. In the second, the accomplices, buyers and property owners named by witnesses, the polygraph results, and the suspects cleared by testing point toward a network. Lanning's monograph states the FBI's position on the network claims. Dovey's account and the cult theories of Terry and Howard supply a network version of the same cases. In the Belgian material, the parliamentary commission found indications of networks that benefited from indirect protection but none that explained the failures by itself, the magistrates stated in January 1998 that no element of proof supported the witnesses' statements, and a 2004 broadcast reported that the defense had asked that one of them testify.
