Former FBI man John Douglas on violent childhoods impacting adult behavior: "What always is a debate, is it nature or nurture"

The former chief of the FBI’s Behavioral Science unit, Douglas discussed the role such an upbringing might play in the adult future of those raised within an abusive environment:

“What always is a debate, is it a nature or nurture thing?” he noted. “I can say from the people who I have interviewed, on death row or in prisons around the country, most of them will have some type of violence, psychological, physical violence, sexual violence in the background.”

The man who served as the inspiration for the character of Jack Crawford in the well-known “Silence of the Lamb” film, Douglas was careful to avoid holding one’s childhood entirely responsible for later behavior:

“However, I’m kind of tough on this because I still don’t believe it should be a mitigating factor,” he told Piers Morgan. “They still have the ability to make choices and [use] free will and they’re making these choices and it’s the wrong choices.”

Serial Killers and their sexual deviations

In the FBI’s study of serial killers, the Criminal Personality Research Project, each of the following categories describes a type of sexual behaviour engaged in by one or more of the serial killers: 

1. Animal Torture: stabbing or chopping animals to death (especially cats for some reason) and dissecting them.

2. Anthropophagy: Eating the victim’s flesh or slicing off parts of flesh from the body.

3. Autoeroticism: Sexual arousal and gratification through self-stimulation (masturbating to pornography or violent fantasies, asphyxia, while cross-dressing, etc.)

4. Coprophilia: An interest in feces whereby the offender may receive some sexual gratification from touching or eating excretement and/or urine (urophilia). Although rare among serial killers, at least one of the killers in the study was known to have eaten his own excretement.

5. Exhibitionism: Exposing one’s genitals to an unsuspecting stranger.

6. Fetishisms: Finding sexual gratification by substituting objects for the sexual partner.

7. Gerontophilia: Seeking out elderly persons of the opposite sex for sexual purposes.

8. Klismaphilia: Sexual arousal through the administration of enemas.

9. Infibulation: Self-torture, for example piercing one’s own nipples, scrotum, labia with sharp objects such as needles and pins.

10. Lust Murder: Murdering sadistically and brutally, including the mutilation of body parts, especially the genitalia.

11. Necrophilia: Having sexual relations (or fantasies about sex) with dead bodies. A subcategory is necrofetishism, which is having a fetish for dead bodies, and these offenders may keep corpses in their home.

12. Pedophilia: Having sexual relations with children (generally child refers to a pre-pubescent individual)

13. Pederasty: Adults have anal intercourse with children. This is a common act among serial killers who target children.

14. Pyromania: Intentional setting of fires. Although some pyromaniacs report sexual gratification in setting or watching fire scenes, the role of sexuality in fire-setting does not appear as the primary reason for such behaviour.

15. Rape: Having forced sexual intercourse with another person.

16. Sadomasochism: Inflicting mental/physical pain on others (sadism) or oneself (masochism).

17. Scatolophilia or Telephone Scatologia: Sexual gratification through the making of obscene phone calls.

18. Scoptophilia or Voyeurism: Receiving sexual gratification by peeping through windows and so forth to watch people.

19. Torture: Resorting to a large variety of sadistic acts.

The Profiling Process
The profiling process is defined by the FBI as an investigative technique by which to identify the major personality and behavioral characteristics of the offender based upon an analysis of the crime(s) he or she has committed. The process generally involves seven steps.
Evaluation of the criminal act itself
Comprehensive evaluation of the specifics of the crime scene(s)
Comprehensive analysis of the victim
Evaluation of preliminary police reports
Evaluation of the medical examiner’s autopsy protocol
Development of profile with critical offender characteristics
Investigative suggestions predicated on construction of the profile
The process used by the person preparing a criminal personality profile is quite similar to that used by clinicians to make a diagnosis and treatment plan: Data is collected and assessed, the situation reconstructed, hypotheses are formulated, a profile developed and tested, and the results reported back. Criminal personality profiling has been used by law enforcement with success in many areas and is viewed as a way in which the investigating officer can narrow the scope of an investigation. Profiling unfortunately does not provide the identity of the offender, but it does indicate the type of person most likely to have committed a crime having certain unique characteristics.

TYPOLOGIES OF MURDER

In essence serial murderers should include any offenders, male or female, who kill over time. Most researchers agree that serial killers have a minimum of 3-4 victims, and the FBI Symposium in 2005 reduced the number to a minimum of 2 victims. Usually there is a pattern in their killing that may be associated with the types of victims selected or the method or motives for the killing. This includes murderers who, on a repeated basis, kill within the confines of their own home, such as a woman who poisons several husbands, children, or elderly people in order to collect insurance. In addition, serial murderers include those men and women who operate within the confines of a city or a state or even travel through several states as they seek out victims. Consequently, some victims have a personal relationship with their killers and others do not, and some victims are killed for pleasure and some merely for gain. Of greatest importance from a research perspective is the linkage of common factors among the victims-for example, as Egger (1985) observed, “victims’ place or status within their immediate surroundings (such as vagrants, prostitutes, migrant workers, homosexuals, missing children, and single and often elderly women)”. Commonality among those murdered may include several factors, any of which can prove heuristic in better understanding victimization.

Much of our information and misinformation about criminal offenders is based on taxonomies, or classification systems. Megargee and Bohn (1979) noted that researchers usually created typologies based on the criminal offense. This invariably became problematic because often the offense comprised one or more subgroups. Researchers then examined repetitive crime patterns, which in turn created new complexities and problems. Megargee and Bohn further noted that, depending on the authority one chooses to read, one will find between two and eleven different types of murderers (pp. 29-32). Although serial murder is believed to represent a relatively small portion of all homicides in the United States, already researchers have begun the difficult task of classifying serial killers. Consequently, various typologies of serial killers and patterns of homicides have emerged. Not surprisingly, some of these typologies and patterns conflict with one another. Some are descriptions of causation, whereas others are diagnostic in nature. In addition, some researchers focus primarily on individual case studies of serial killers, whereas others create group taxonomies that accommodate several kinds of murderers.

Wille (1974) identified ten different types of murderers covering a broad range of bio-socio-psychological categories:

  1. depressive
  2. psychotic
  3. afflicted with organic brain disorder
  4. psychopathic
  5. passive aggressive
  6. alcoholic
  7. hysterical
  8. juvenile (the child was the killer)
  9. mentally retarded
  10. sex killers

Lee (1988) also created a variety of labels to differentiate killers according to motive, including:

  1. profit
  2. passion
  3. hatred
  4. power or domination
  5. revenge
  6. opportunism
  7. fear
  8. contract killing
  9. desperation
  10. compassion
  11. ritual

Even before American society became aware, in the early 1980s, of serial murder as anything more than an anomaly, researchers had begun to classify multiple killers and assign particular characteristics and labels to them. Guttmacher (1973) described the sadistic serial murderer as one who derives sexual gratification from killing and who often establishes a pattern, such as the manner in which they kill or the types of victims they select, such as prostitutes, children, or the elderly. Motivated by fantasies, the offender appears to derive pleasure from dehumanizing his or her victims. Lunde (1976) recognized and noted distinctions between the mass killer and the serial killer, notably that the mass killer appears to suffer from psychosis and should be considered insane. By contrast he found little evidence of mental illness among serial killers. Danto (1982) noted that most serial murderers may be described as obsessive-compulsive because they normally kill according to a particular style and pattern.

Researchers have been attempting to create profiles of the “typical” serial killer from the rapidly accumulating statistics on offenders and victims in the United States. The most stereotypical of all serial murderers are those who in some way are involved sexually with their victims. It is this type of killer who generates such public interest and alarm. Stories of young women being abducted, raped, tortured, and strangled appear more and more frequently in the newspapers.

Fantasy and serial murder
ALL of the murderers interviewed by the FBI, during their Criminal Personality Research Project had compelling fantasies where they could control their world.
They overcompensated for the aggression in their early lives by repeating the abuse in fantasy, but this time, with themselves as the aggressors. Fantasy is defined as a happenstance unattainable in normal life. “Normal” people learn to accept social control and moderation as limits on their behavior. The deviant person, having had very few true restraints on his behavior since childhood, believes he can act out his fantasy and that nobody will be able to stop him.
The offender’s commitment to the fantasies deepens as he becomes a loner in adolescence, subject to the onset of puberty and sexual arousal. Aggressive, and with a feeling of having been cheated by society, he may channel his hostility into fantasies, which are characterized by strong visual components, and by themes of dominance, revenge, molestation, manipulation, and control. The other person is depersonalized, made into an “object”.
Deviants feel the sexual urge without having learned that it has anything to do with affection.
The cognitive mapping process is almost complete by now, It is the development of thinking patterns that affect how the person relates to himself and to his environment, it determines how the individual gives meaning to the events that happen in his world.
He views the world as a hostile place. He becomes almost incapable of interacting properly with the outside world, because his thinking patterns are all turned inward, designed only to stimulate himself in an attempt to reduce tensions, which only reinforces his isolation: a loop has developed. The effects of his antisocial acts (i.e. cruelty to animals and other children, arson) become incorporated into his fantasies, which are pushed to a more intensively violent level.
More retreat from society follows, and, eventually, so do more experiments with actualizing the fantasies
After rehearsals, and minor attempts at acting out the fantasy -all it really takes is a stressor for him to try and make the fantasy a reality.

FBI Profiler, Robert Ressler’s 1984 paper, presented to the International Association of Forensic Sciences, he and his colleagues listed the following as “general characteristics” of serial sex murderers:
over 90% are white males
they tend to be intelligent, with high IQ’s, in the bright normal range
in spite of their IQ’s, they do poorly in school, have a hard time holding down jobs, and often work as unskilled laborers
they tend to come from markedly unstable families: typically, with an absent father and domineering mother
their families often have criminal, psychiatric and alcoholic histories
they hate their parents
they are commonly abused as children - psychologically, physically and sexually
many end up spending time in institutions as children, and have records of early psychiatric problems
they have a high rate of suicide attempts
they are intensely interested, from a very early age, in voyeurism, fetishism and S&M pornography
In addition, the Homicidal Triad (McDonald Triad) is also noted (bedwetting, firesetting, cruelty to animals - or other children)

Retired FBI Profiler, Roy Hazelwood, discussing the Harvey Glatman case in an interview with Dr. Katherine Ramsland. 

“When I was a second lieutenant in the military police corps, in basic training for officers at Fort Gordon, Georgia, one of the presentations in this course was the Harvey Glatman case. That case caused me to become interested in violent crime. He was the first person in modern times that I’m aware of that kept his victims in captivity for a period of time, engaged in bondage, and took photographs. He also practiced dangerous autoeroticism at a young age. So I asked the instructor why Glatman tied these women in a variety of positions, why he took pictures, and why he didn’t destroy the pictures, because they were used against him. I was told that information wasn’t important. All that was necessary for me to know was that this man had killed three women. So I decided that if I ever got in a position where I could learn more about this type of offender, I was going to do so. He was one of the original modern serial killers in America. He did a lot of the things that we now look at as being commonplace, but at that time it was unusual.

An interesting note to that story is that the homicide detective assigned to that case was a guy named Pierce Brooks. He said to himself, “If he’s killed this many women here, he’s bound to have killed women in other places.” So he went to the library and did a paper search, looking for similar killings. Then he went to his police chief in Los Angeles and said, “Look, I think we need to buy a computer, enter these kinds of cases, and see if we can’t match these cases together.” The chief scoffed at the idea, because a computer at that time would cost one million dollars and take up a city block. Then in the early eighties, Brooks got the Department of Justice to host a conference at Sam Houston State University, and that’s when VICAP, the Violent Criminal Apprehension Program, was born. Glatman’s case started that whole process. It was decided that the FBI would run it out of Quantico and in 1985, we hired Brooks to become the first director of VICAP, because it was his idea. So I got to meet him, and I said to him, “You worked the Harvey Glatman case.” He was surprised. “No one knows that,” he said. I told him I’d studied it. He ended up giving me the original photographs that Glatman took. It even had Brooks’s initials from the day he seized them as evidence. So all those years later, from 1960 to 1985, Glatman came full cycle in my life.”

Serial Rape - a study by FBI profiler Roy Hazelwood
The research concerning serial rapists’ behavior during and following the commission of the crimes has determined that:
The majority of the rapes were premeditated
The “con” approach was used most often in initiating contact with the victim
A threatening presence and verbal threats were used to maintain control over the victim
Minimal or no force was used in the majority of instances
The victims physically, passively or verbally resisted the rapists in slightly over 50% of the offenses
The most common offender reaction to resistance was to verbally threaten the victim
Slightly over one-third of the offenders experienced a sexual dysfunction, and the preferred sexual acts were vaginal rape and forced fellatio
Low levels of pleasure were reported by the rapists from the sexual acts
The rapists tended not to be concerned with precautionary measures to protect their identities
Approximately one-third of the rapists had consumed alcohol prior to the crime and slightly less reported using some other drug.
The most common post-offense behavior reported by the rapists were feelings of remorse and guilt, following the case in the media and an increase in alcohol and drug consumption. These characteristics, although not generally applicable to every rapist, can be helpful in learning more about offenders, their behaviors and the heinnous crime of rape

Catching a Serial Killer - Investigative Recommendations
According to the experts, there is no common thread tying serial killers together—no single cause, no single motive, no single profile. But there are some common “best practices” that they recommend for investigations:
For example:
Strong leadership throughout the chain of command that can withstand the external pressure sometimes brought to bear on serial murder cases by politicians, the victims’ families, and the media;
Task forces that bring together agencies from the different jurisdictions to effectively combine expertise, resources, and information;
An automated case management system like the FBI’s Rapid Start that organizes and collates lead information so investigators don’t get overwhelmed;
A team of crime analysts who can help investigators develop timelines of murders and backgrounds on suspects, highlight similar case elements, etc. (note: if your agency doesn’t have such a team, ask for help from a neighboring jurisdiction or from our National Center for the Analysis of Violent Crime);
Consistent forensic services, which in the best case scenario means that the same crime scene team goes to each scene and the same crime lab processes all the evidence (but if that’s not possible, then enhanced communication between the teams and the labs is a must to ensure consistency); and
A strong media plan that successfully straddles the line between giving out relevant information to the media and not compromising the investigation—while helping to raise public awareness about the killings

John Wayne Gacy, in an interview with retired FBI Profiler, Robert Ressler
Ressler: The media have called you a homosexual killer. What is your position on homosexuality?
Gacy: I have nothing against it. I am an outpsoken liberal. I don’t care for the labeling. I don’t care for any labeling, for that fact.
Ressler: Do you claim to be a homosexual?
Gacy: No, I would definitely not be homosexual. I have nothing aginst what they do, and I don’t deny that I engage in sex with males, but that’s - I am bisexual.
Ressler: You’re bisexual?
Gacy: Right. My preference is women, and I have been married enough times and have children, and I see nothing wrong with it. They blew this out of proportion, because, again, it enforced their sexual angle of the case. I am not homosexual, not in any sense of the word, I says, ‘cause I was married twice; and just because I didn’t get along in my marriages - My marriages went down the drain only because I was a workaholic, working seven day a week and that -
Gacy always expressed anger that he was accused of having sex with his victims. His second wife had reported that they rarely had sex, and their children were adopted. Gacy’s father reportedly often said to him, as a child, “you’re queer”, or “you’re going to turn out to be a queer”. Robert Ressler writes:
“Gacy had a great need in general for denial, and specifically to deny the notion that he was a homosexual. In our previous conversations, however, Gacy had indicated that homosexual acts were a matter of convenience to him: he was the sort of guy who’d put in eighty-hour workweeks, and because of this heavy schedule he didn’t have time for dating women…It was much easier for him to pick up a young guy to give him oral sex and it wouldn’t cost much; that would hold him for a few weeks and enable him to go back to work. But why didn’t he go to a female prostitute, which would have been accessible? Gacy goes to great lengths to deny his homosexuality, as though there were some aspects of homosexuality that he finds reprehensible”.

Gacy’s father reportedly often said to him, as a child, “you’re queer”, or “you’re going to turn out to be a queer”. Robert Ressler writes:

“Gacy had a great need in general for denial, and specifically to deny the notion that he was a homosexual. In our previous conversations, however, Gacy had indicated that homosexual acts were a matter of convenience to him: he was the sort of guy who’d put in eighty-hour workweeks, and because of this heavy schedule he didn’t have time for dating women…It was much easier for him to pick up a young guy to give him oral sex and it wouldn’t cost much; that would hold him for a few weeks and enable him to go back to work. But why didn’t he go to a female prostitute, which would have been accessible? Gacy goes to great lengths to deny his homosexuality, as though there were some aspects of homosexuality that he finds reprehensible”.

Prevalence of Serial Murder in the United States

The FBI estimates that there have been approximately 400 serial killers in the United States in the past century, with anywhere from 2,526 to 3,860 victims. However, there’s no way to really know how many serial killers are active at any point in time — experts have suggested numbers ranging from 50 to 300, but there’s no evidence to support them.

Eighty percent of the 400 serial killers of the past century have emerged since 1950. Why this is happening is a question of some debate; there is no answer, just as there is no simple answer as to why some people become serial killers.

Profiling the Vampire of Sacramento
Psychological profiling proved its worth in the capture of Richard Trenton Chase, the so-called “Vampire of Sacramento.” After he murdered a woman and drank her blood in 1978, the FBI, concerned at the brutality of the crime, called in the profilers. They noted the disorder at the scene and, from a study of body type and mental temperament, concluded the murderer was white, thin, undernourished, and in his mid-twenties. As a disorganized type, he’d beunemployed and live alone. They also guessed he would kill again and, unfortunately, three days later he did. He murdered three people in their own home, stole the family car and then abandoned it. The second murder provided more information to refine the profile. Chase was soon found, living locally, and he fit the profile. He had a history of mental illness, admitted the crimes, but did not see he had done wrong. He told his interrogators that his own blood was turning to sand, so he had to become a vampire. The capture of Chase saved many lives - he had more murders planned and marked down on a calendar found in his room.
