Serial Killers

Serial killers are criminals who commit three or more murders over a considerable period of time, for psychological and psychopathic gratification.

Who Is A Serial Killer?

A serial killer is a type of multicide perpetrator who kills three or more people over a long period of time ¹. Modern criminology explains that serial killers display amplified traits of psychopathy ², exhibiting

• shallow affect
• lack of empathy, guilt and remorse
• irresponsibility, and
• impulsivity.

What Is Serial Killing?

Serial killing or serial homicide is a premeditated, consciously perpetrated, voluntary act of violence directed to cause harm or loss of life.

According to a 2020 study ³, serial killing or serial homicide is an all-inclusive term for the “unlawful killing of two or more victims in separate events”. The threshold number of murders ⁴ in a serial killing range from 3 to 5 but is never less than two.

Serial killers typically won’t stop until they have been killed or caught by law enforcement. In most cases, they follow a pattern ⁵ with respect to their type of victims, killing methods, killing frequency, etc

Serial killing is often accompanied by other crimes such as rape, burglary, necrophilia, pedophilia, theft, spree killing, etc.

Serial Killing Vs Mass Murder

Serial killing is often confused with other types of multicide ³ like mass murder, spree-killing, or contract killing. However, despite the conceptual similarities, the acts are essentially different—distinguished by factors ⁶ like:

• Timeline
• Number of homicides
• Number of victims
• Killing methods
• Motives
• Others

For instance, mass murder is four or more murders occurring at one event without any distinctive time lapse between them. On the other hand, spree-killing is any murder that occurs at two or more locations with no emotional cooling-off period in-between.

In contrast, the sure signs of a serial killer comprise murdering three or more people, with cooling-off periods in-between, over a lengthy stretch of time.

The Psychology Behind Serial Killing

A question that intrigues most people is: How do serial killers think? What makes them kill?

In a majority of cases, crime experts attribute this psychopathy to harrowing developmental experiences ³ and mental deterioration . Such experiences hark back to:

• Childhood abuse
• Early separation from mother
• Sexual abuse
• Domestic violence
• Poverty
• Social or romantic failures, etc.

More often than not, serial killers act on motives ⁷ drawn from:

• Anger
• Thrill-seeking
• Lust
• Profit or power seeking
• Need for attention
• Financial gain ⁸
• Fulfilling a delusional goal, etc.

Irrespective of the motive, all serial killers operate on one base reason: killing for the act of killing itself. Often victims are chosen randomly; at other times, they choose their victims based on their fantasy of the “ideal victim” and certain social reservations based on race, gender, physical characteristics, etc.

Most serial killers, during trial, have been medically evaluated and popularly speculated to be suffering from serious mental health conditions. However, even if serial killers are considered mentally unstable ⁹, they are not adjudicated as such under the law.

Traits Of A Serial Killer

The time-tested Macdonald triad, ¹⁰ formulated in 1963 by the renowned psychiatrist J. M. Macdonald is still used in modern times to predict or detect violent criminal tendencies, especially those associated with serial homicide.

According to this triad of sociopathy, the telling signs of a ‘born’ serial killer ¹¹ are already present in childhood. These involve:

• Arson, or setting fires
• Cruelty to animals
• Enuresis, or unintentional bed-wetting during sleep

However, the Macdonald triad has seen much flexibility and elaboration in recent years, thanks to rigorous in-field practices in criminology and forensic studies. Recent research ¹² throws light on the characteristics of a serial killer, which include:

• Signs of psychopathy
• Egocentrism
• Grandiose and sadistic ideas of pleasure
• Being cruel, ruthless, and remorseless
• Having no or shallow emotions
• Lack of basic human values (like empathy)
• Lack of responsibility for their crimes
• Superficial charm
• Deceitful, and manipulative behavior
• Poor conduct control (like impulsivity, recklessness, etc.)
• Tendencies related to vandalism, arson, theft, etc.
• Extreme risk-taking behavior.

A lot of serial killers are also diagnosed with mental health conditions, such as:

• Antisocial personality disorder
• ADHD [Read More]
• Narcissistic personality disorder [Read More]
• Substance abuse disorders
• Schizophrenia [Read More]
• Psychosis [Read More], etc

Types Of Serial Killers

Based on their ‘human’ characteristics, serial killers are primarily distinguished into two major types ¹³:

1. Organized Killers

Organized killers are meticulous in planning and executing their murders. They plan out every detail of their crime in advance and take caution to not leave behind any incriminating evidence.

These killers handpick their victims according to their obsessions or fancy. They are also more likely to engage in fetishism, partialism, necrophilia, or human trophy collection. It is found that most organized serial killing cases around the globe concern children, young women, homosexual men, couples, etc.

2. Unorganized Killers

Unorganized killers do not plan out their crimes beforehand and are haphazard in their execution. Most often, they have deep-seated mental illnesses that trigger their homicidal behavior.

These killers, in the absence of thorough planning, randomly select their crime spots; but, even then, they target a select social group.

Organized and unorganized killers can, in turn, be distinguished into several types based on their motives for serial homicide ¹³. These include:

1. Visionary Killers

A visionary serial killer operates to satisfy their personal visions. These visions are more or less grandiose (larger than life) delusions of an unstable mind associated with religious beliefs, ritualistic practices, and participation in the occult.

Examples of this type of killer include Herbert Mullin and Richard Chase who murdered people in the 1970s as blood sacrifices.

2. Mission-oriented Killers

Mission-oriented serial killers kill to “rid” society of a specific group of people. These killers are mostly linked to racist, religious, and ethical extremism.

Examples of mission-oriented serial killers include Joseph Paul Franklin who targetted Jews, Blacks, and interracial couples, during 1977–80, in America.

3. Hedonistic killers

A hedonistic serial killer is a homicide perpetrator who thrives on hedonism and kills for pleasure. This type of serial killer is usually driven by the “thrill of the kill”, sex, or money.

Hedonistic killers can further be divided into three types:

I. Lust killer

A lust serial killer tortures, rapes, and mutilates victims for their own sexual gratification. Good examples of lust killers are Theodore “Ted” Bundy and “Killer Clown” John Wayne Gacy.

II. Thrill killer

A thrill killer kills for the pleasure of killing and satisfying their adrenaline rush through stalking, death threats, break-ins, etc. A good example is Robert Hansen who stalked and murdered at least seventeen women in Alaska in the years 1980–83.

III. Comfort killer

A gain or comfort killer is a serial killer who kills for “profit” aka monetary or material gains. A good example is Dr. Henry Howard Holmes, a comfort killer who operated in Chicago during the late nineteenth century.

4. Killers Seeking Power/Control

A power or control serial killer is someone who seeks to gain power and control over their victims. Their most common expressions of power are organized sexual domination, torture, mutilation, and ‘trophy collection’ of human body parts. Such grotesque collections, according to experts, serve to empower the perpetrators.

The Zodiac Killer, who terrorized the San Francisco Bay Area, the US, in the 1960s is a good example of killers seeking power and control.

Serial Killer Myths

Serial killers and serial killings are the subjects of never-ending fascination, urban legends, and paraphilia. The seamless crime documentaries and debates show how fascinated people are by the grotesque murder methods, the twisted psychology of the perpetrators, the techniques to avoid detection, and subsequent incarceration, trial, and punishment.

Nonetheless, most serial killing cases have witnessed extreme media frenzy and stereotypical representations and, over the years, have accumulated a substantial body of myths and false, exaggerated notions.

Some of the most common serial killer myths include:

1. All serial killers are men.

Serial killers can be both men and women, even though female serial killers are rare compared to their male counterparts. In some cases, because of the meticulous documentation of modern-day serial killers in the US, it is widely believed that serial killers are mostly white men. This is not true.

For instance, a 2006 study ¹⁴ claims that, compared to 77% of male serial killers, female serial killers amount to 23%. It was also found that the most common motive for men was material gain or similar extrinsic gratification while women rarely were ‘hedonistic’ killers, who killed for sexual gratification.

2. All serial killers have an above-average IQ.

It is widely believed that serial killers are geniuses with an IQ level above the average person. Instead, it is found that serial killers are in reality, people of average intelligence with enhanced streaks of psychopathy ¹⁵.

3. All serial killers are motivated by sex.

It is a popular notion that all serial killings are lust killings. This is a predominant generalization, as serial homicide is motivated by several causes (such as material gains, visions, the thrill of adventure, etc.)

4. All serial killers can’t stop killing.

It is widely believed that serial killers do not stop until they have been killed or caught by law enforcement. In some cases (like the Zodiac Killer), the killer stops on their own accord without any incarceration or death sentence.

5. All serial killers have mental health conditions.

Criminal psychology always strives to locate the motive of serial killings in the murky minds of the perpetrators. Experts try to signal out certain mental disorders—like schizophrenia, ADHD, psychosis, antisocial personality, and narcissistic disorders—that appear to contribute to the killing spree and associated wicked acts.

They have tried to trace and recognize the source of such mental health conditions, like childhood abuse, trauma, parental violence, bullying, etc. Hence, more often than not, people consider serial killers as “social casualties”. They fail to see that serial killers mostly kill for the sake of killing itself.

6. All serial killers want to get caught.

Many people think serial killers, who are too knee-deep in crime, get deranged and long to be discovered so as to put an end to their killing spree. However, as case studies show, all criminals do not long to be caught. They take extreme care to escape the consequences of their actions and that is why when they get caught—it is usually by accident.

An Infamous “Serial Killers” List

Some of the worst serial killers in history include:

1. Jack The Ripper

The foremost modern and most notorious serial killer in history, the anonymous “Jack The Ripper” operated in Victorian London, in the 1880s. He raped, murdered, and mutilated at least 5 prostitutes and is the subject of an unending stream of urban legends.

2. Ted Bundy

Perhaps the most notorious of male serial killers, Theodore “Ted” Bundy was charged with lust serial killing of at least 30 women, across 5 American states, between 1973 and 1978. In prison, he was diagnosed with antisocial personality disorder and mania as he exhibited different appearances, signatures, names, and criminal methods at different times.

3. Vera Renczi, “The Black Widow”

The most famous female serial killer, Vera Renczi or “The Black Widow” was a Romanian serial killer who killed 35 men by arsenic poisoning. Her victims included her husbands, her lovers, and her children.

Takeaway

More often than not, what we know of serial killers are products of colorful storylines and headlines. These were directed to create “larger than life” socially constructed “celebrity monsters” who reduced the severity of their criminal actions into stylish “wickedness” and piqued newspaper sales.

Nonetheless, this “wickedness”—time and again—poses significant investigative challenges to law enforcement, not to mention attracting an over-abundance of attention from the media, mental health experts, academia, and the general public.
