"THE LIFE AND CRIMES OF THE NOTORIOUS SERIAL KILLER - HERBERT MULLIN"

 

The Life and Crimes of Herbert Mullin

Early Life and Family Background (1947–1960s)

Herbert William Mullin was born on April 18, 1947, in Salinas, California, USA. He grew up in a middle-class family and, unlike many serial killers, initially appeared well-adjusted.

His father was a strict but stable figure, working in the military.

His mother was protective and attentive.

Mullin was described as intelligent, polite, and sociable in childhood.

He was even voted “Most Likely to Succeed” in high school—a detail that makes his later transformation particularly unsettling.

Turning Point

A major emotional rupture occurred in his late teens:

His best friend died in a car accident.

Mullin reportedly became deeply withdrawn afterward.

This loss is widely considered a key psychological trigger.

Psychological Decline and Early Warning Signs

After high school, Mullin’s behavior changed dramatically:

He began abusing drugs, particularly marijuana and hallucinogens.

He developed paranoid thoughts and erratic behavior.

He was diagnosed with schizophrenia and was in and out of psychiatric institutions.

His symptoms included:

Auditory hallucinations (hearing voices)

Delusions of cosmic importance

A belief that he had a special role in preventing disasters

At times, he resisted treatment and stopped taking medication, worsening his condition.

The Delusion: Preventing Earthquakes

Mullin became obsessed with the idea that human sacrifices could prevent earthquakes.

California—especially areas near the San Andreas Fault—was at risk of a catastrophic event.

He believed:

The Vietnam War had “satisfied” the need for human sacrifice.

When the war ended, he felt compelled to “replace” those deaths to maintain balance.

This delusion became the driving force behind his murders.

First Murder and Entry into Killing (October 1972)

Mullin’s first confirmed killing occurred in October 1972.

Victim: A homeless man.

Method: Beaten to death with a baseball bat.

Mullin later claimed the following:

The man volunteered as a sacrifice.

The act was necessary to prevent an earthquake.

This marked the beginning of a rapid and intense killing spree.

The Killing Spree (October 1972 – February 1973)

In just four months, Mullin murdered 13 people across Santa Cruz County, California.

Victim Profile

His victims were highly varied:

Homeless individuals

A college student

A priest

A married couple

Teenagers

A family (including children)

This randomness reflected his delusional thinking rather than typical criminal targeting.

Notable Murders

1. The Hitchhiker

A female college student picking him up.

He stabbed her to death after she rejected his advances.

2. The Priest

Mullin entered a church and killed a Catholic priest.

He later claimed the priest was offering himself as a sacrifice.

3. The Family Killings

Mullin murdered a man, his wife, and their two children.

He believed the father had mentally instructed him to do so.

4. The Teenagers in the Forest

He shot several young men camping in the woods.

Claimed they were polluting the environment and needed to die.

Modus Operandi

Mullin’s methods varied:

Shooting

Stabbing

Bludgeoning

Unlike many serial killers:

He did not attempt to conceal bodies.

He often acted impulsively.

His crimes were driven entirely by delusion rather than sexual or material motives.

Investigation and Growing Panic

The sudden surge of murders caused fear across Santa Cruz County.

Law enforcement initially struggled because the victims had no clear connection.

The methods differed.

There was no obvious motive.

However, patterns began to emerge:

Geographic clustering

Timeline proximity

Witness descriptions of a strange, disheveled man

Arrest (February 13, 1973)

Mullin’s capture was swift after his final murders.

He shot a man named Fred Perez while the victim was working in his yard.

Witnesses reported the crime immediately.

Police quickly located Mullin:

He was found driving nearby.

He was still in possession of the murder weapon.

He was arrested without resistance.

Confession and Statements

After arrest:

Mullin openly admitted to the killings.

He explained his earthquake-prevention theory in detail.

He showed:

No conventional remorse

A firm belief that his actions were necessary and justified

Trial and Verdict (1973)

Mullin’s trial focused heavily on his mental state.

Defense Argument

He was legally insane due to schizophrenia.

He could not distinguish reality from delusion.

Prosecution Argument

Despite his illness, he knew his actions were wrong.

Evidence: attempts to avoid detection in some cases.

Verdict

Mullin was found guilty of multiple counts of murder.

He was declared legally sane.

Sentenced to life imprisonment.

Imprisonment and Behavior

Mullin spent decades in prison in California.

Notable aspects of his incarceration:

He continued to express his delusional beliefs for years.

Later reports suggested some stabilization with treatment.

He became something of a subject of study in forensic psychology.

Interestingly:

He was once housed near Edmund Kemper, another notorious killer.

Kemper reportedly complained about Mullin’s behavior and even threw water on him to keep him quiet.

Death (2022)

Herbert Mullin died on August 18, 2022, at the age of 75 while still in custody.

Cause of death was not widely emphasized publicly.

He never received parole.

Aftermath and Impact

The Mullin case had lasting effects:

Public Impact

Heightened fear in California during the killings.

Increased awareness of random, non-patterned serial crimes.

Legal and Psychological Impact

Became a key case in debates about:

Insanity defense

Criminal responsibility in schizophrenia

Studied in criminology for:

Mission-oriented killers

Delusion-driven violence

Psychological Profile

Mullin is often categorized as:

A mission-oriented killer

A psychotic offender

A schizophrenic with command hallucinations

Key traits:

Strong belief in a personal “duty”

Disorganized but purposeful violence

Lack of typical serial killer gratification motives

Current Status of the Case

The case is closed.

All murders were attributed to Mullin.

He died in prison, ending any possibility of release.

Today, his crimes are studied as an extreme example of the following:

Untreated severe mental illness

The dangerous intersection of delusion and perceived moral duty

Final Reflection

Herbert Mullin’s story is less about calculated evil and more about the following:

Severe mental illness left inadequately controlled

A mind constructing its own reality

Violence justified by deeply distorted beliefs

It remains one of the most chilling examples of how delusion—not just malice—can drive catastrophic human behavior.
