Zodiac: The Most Wanted Serial Killer of 20th Century

On December 20, 1968, a young couple went out on their first date. Wanting some privacy, they drove toward Lake Herman in California.

In the car were 16-year-old Betty Lou Jensen and 17-year-old David Faraday. Completely unaware… someone was following them.

They had just parked near the lake when another car pulled up behind them. The man inside ordered them to step out. When they refused, he fired a shot at their car’s rear wheel to scare them.

Terrified, David and Betty ran—but the man shot both of them. David was hit in the head, and Betty was shot five times in the back.

The killer fled the scene.

This chilling incident marked the beginning of the hunt for one of the most infamous serial killers in history…

Yes—we’re talking about the Zodiac Killer.

Welcome back .

The Zodiac Killer is considered one of the most terrifying serial killers of the 20th century. Between the late 1960s and early 1970s, he spread fear across San Francisco.

He would send letters to newspapers and police—boasting about his murders and even including cryptic puzzles to challenge them.

After his first double murder, he went silent for six months…

Then he struck again.

July 4, 1969 – Independence Day

18-year-old Darlene Ferrin and 16-year-old Michael Mageau were out to buy fireworks. They noticed a car following them.

Trying to escape, they turned into the parking lot of Blue Rock Springs Park—but the car followed.

At first, the stranger drove up beside them… then left.

Relieved, they thought the danger had passed.

But moments later, the car returned—this time blocking their way.

A man stepped out holding a powerful flashlight, shining it directly into their faces. They thought he might be a police officer…

But suddenly, he opened fire.

Darlene died on the spot. Michael survived with injuries.

Later that night, at 12:40 AM, the Vallejo Police received a strange call from a phone booth—but the caller hung up before saying anything.

This was the Zodiac Killer’s first contact with police.

A month later, on August 1, 1969, he sent letters to three newspapers, confessing both murders.

To prove it, he included details only the police knew—like bullet types and victim clothing.

He also included a coded message—a cipher—and demanded it be published, or he would kill again.

The cipher was eventually cracked by a civilian couple. It read:

“Killing is more fun than hunting wild game… because man is the most dangerous animal.”

He also claimed he believed in the afterlife—and that his victims would become his slaves there.

After two months of silence, he struck again.

September 27, 1969

A college couple, Bryan Hartnell and Cecelia Shepard, were relaxing near Lake Berryessa.

A man approached wearing a black hood with a strange symbol—the Zodiac sign.

He tied them up at gunpoint… then stabbed them multiple times.

Cecelia later died. Bryan survived and described everything.

Before leaving, the killer wrote a message on their car door—listing dates, locations, and weapons used.

That same night, he called the police again—confessing the crime.

By now, police noticed a pattern:

He targeted young couples

Attacks happened on weekends or holidays

Usually at night or dusk

He took pride in his crimes

Locations were often dating spots

Victims were usually in cars

Crimes occurred near water

But then… he broke his own pattern.

October 11, 1969

He killed a taxi driver named Paul Stine in San Francisco—shooting him at point-blank range.

Witnesses saw him and called the police.

Officers even encountered him nearby—but let him go… because they were mistakenly looking for a Black suspect.

The killer escaped again.

He later sent letters to newspapers, including a piece of Paul Stine’s shirt as proof.

He even threatened to attack school buses—causing widespread panic.

In 1969, he called a TV show, claiming he wanted to speak to lawyer Melvin Belli.

But later, it was revealed that the caller was actually a mental patient—not the Zodiac.

Years passed, and more letters came—some with complex ciphers.

One cipher remained unsolved for over 50 years—until 2020, when it was finally cracked using computer software.

Surprisingly, it revealed no major clues—only that the TV caller wasn’t him.

In one letter, he claimed to have built a bomb in his basement—suggesting he might live in a house, not an apartment.

In 1970, he allegedly tried to kidnap a woman named Kathleen Johns—but she escaped.

She later identified him from a sketch.

Over the next four years, he continued sending letters—sometimes describing murders, sometimes reviewing movies.

His final letter came on January 30, 1974.

In it, he wrote:

“Me: 37 — SFPD: 0”

Claiming 37 victims—though police believe he was responsible for only about five.

Investigators concluded he likely had:

Military training

Knowledge of cryptography

Specialized boots used in military stores

Many suspects were investigated.

One major suspect was Arthur Leigh Allen—but fingerprints and handwriting didn’t match.

Another was Richard Gaikowski—but again, no solid proof.

In total, over 50 suspects were examined… yet none could be definitively identified as the Zodiac.

To this day, the identity of the Zodiac Killer remains one of the greatest mysteries in criminal history.

Who was he?

Why did he kill?

And what was his real motive?

No one knows.
