A 32-Year DNA Breakthrough Exposes a Hidden Predator — The 1991 Washington Cold Case That Finally Revealed the Truth

On the morning of December 14, 1991, a 16-year-old girl with bright red hair rushed out of her front door in Federal Way, Washington.

She was still wearing her drill team uniform.

Her hair was still wrapped in curlers.

She didn’t stop to fix them.

She didn’t stop to double-check the time.

She thought she was late.

That single assumption—one small moment of panic—placed her exactly where a predator needed her to be.

Because she wasn’t late.

She was early.

Nearly an hour early.

And in that empty, freezing parking lot behind her high school, she was completely alone.

But she wasn’t the only one there.

Someone else had already arrived.

Someone who had been waiting.

By the time the rest of her team showed up, Sarah Yarborough was gone.

And what happened next would become one of the most chilling unsolved cold cases in Washington state—one that would take more than three decades, advanced DNA technology, and a breakthrough in forensic genetic genealogy to finally solve.


To understand the weight of that morning, you have to understand who Sarah Yarborough was.

She wasn’t just another name in a crime database.

She wasn’t just a headline.

She was a daughter, a sister, a friend—and someone whose presence made people feel better simply by being around her.

Born on June 12, 1975, in Portland, Oregon, Sarah moved with her family to Federal Way when she was just 8 years old.

By high school, she had become the kind of person everyone remembered—not because she demanded attention, but because she gave it.

She was an honors student.

She loved math, science, and art.

She read constantly.

She pushed herself in everything she did.

She wasn’t defined by one talent.

She was defined by her effort in all of them.

Sarah was active in her school’s drill team, participated in church youth programs, and even traveled internationally with a performance group focused on encouraging young people to avoid harmful life choices.

At just 15 years old, she had already seen parts of the world most adults never would.

And she wanted more.

She talked about leaving the state for college.

She dreamed about becoming either a museum curator or an engineer.

But beyond her achievements, there was something else people remembered.

Her kindness.

She helped her younger brothers with schoolwork.

She showed up when people needed support.

She didn’t wait to be asked.

She simply acted.

Her mother described her as the “delight of her life.”

Her motto was simple:

Carpe diem — seize the day.

And she lived by it.

Every single day.


That’s what makes what happened next so devastating.

Because on that cold December morning in 1991, someone took all of her days away.


The night before, everything had been normal.

Sarah’s family was leaving town for her brother’s soccer game.

She asked to stay home so she wouldn’t miss her drill team competition.

Her parents hesitated—but eventually agreed under one condition:

She couldn’t be alone.

A friend stayed over that night.

They went to a basketball game.

They grabbed fast food.

They laughed, talked, and relaxed like any two teenagers would.

There were no warning signs.

Nothing felt wrong.

Nothing suggested that within hours, everything would change forever.


The next morning, Sarah woke up and believed she was late.

She rushed out the door.

She didn’t fix her hair.

Didn’t eat.

Didn’t slow down.

She drove straight to the school.

She parked.

And then she waited.

Because she was early.

Almost an hour early.

The parking lot was empty.

The air was freezing.

Ice had formed overnight.

Everything was still.

Silent.

A teenage girl sat alone in her car with a container of orange juice on the passenger seat—completely unaware that someone nearby was watching her.


What happened next would not be fully understood for 32 years.


Two boys, just 13 years old, would unknowingly walk into the aftermath minutes later.

They had spent the morning watching cartoons.

Eating cereal.

Living a normal Saturday.

Then they decided to go skateboarding.

To save time, they cut through the school grounds—a shortcut they had taken countless times before.

As they crossed the campus, they noticed a man emerging from a hidden area near the bushes.

He stared at them.

Then walked away.

Something about him felt wrong.

But they kept going.

Until they reached the spot where he had been.

And saw something that would stay with them for the rest of their lives.

A young girl lying motionless on the ground.

Unmoving.

Unresponsive.

Gone.


Moments later, they saw the man again.

Standing near a vehicle.

Watching them.

Not running.

Not panicking.

Just watching.

That look would be described later as something unforgettable.

Cold.

Calculated.

Terrifying.

The boys ran.


Police quickly arrived.

They identified the victim.

It was Sarah.

Her car was still in the parking lot.

The orange juice sat untouched.

There were no signs of struggle near the vehicle.

Which meant one thing:

She had left the car willingly—or had been forced to.


Investigators collected evidence.

They found DNA.

A full male profile.

They had witnesses.

They had a timeline.

They had leads.

And yet—

Nothing.

No arrest.

No suspect.


For years, the case remained unsolved.

Thousands of tips came in.

Sketches were distributed.

Fear spread through the community.

But the man responsible remained invisible.


What investigators didn’t fully understand at the time was this:

The person responsible had done something like this before.

And he should have never been free.


Years earlier, a man named Patrick Nicholas had shown a pattern.

He approached women.

Gained trust.

Used a weapon.

Forced them into isolated areas.

He admitted he had dangerous impulses.

He was sentenced to prison.

Ten years.

But he didn’t serve ten years.

He served just three and a half.

Then he was released.

Labeled as safe.

Allowed back into society.


If that sentence had been fully carried out, he would have still been behind bars in 1991.

Sarah would have lived.


But the system failed.

And the consequences were irreversible.


For decades, the DNA sat in a database.

No match.

No answers.

Until a new method emerged:

Forensic genetic genealogy.

Instead of matching DNA to criminals, investigators began matching DNA to family trees.

Tracing ancestry.

Building connections.

Looking for distant relatives.


And that’s when everything changed.

The DNA led to a family line dating back hundreds of years.

From there, investigators narrowed it down.

One branch.

One name.

Nicholas.


Surveillance teams followed Patrick Nicholas.

They waited.

Watched.

Until he discarded something.

A cigarette.

A napkin.

Small, meaningless trash.

Except it wasn’t.


It contained his DNA.

And it matched.

Perfectly.

After 28 years, the identity of the man who had been hiding in plain sight was finally confirmed.


He was arrested in 2019.

The case went to trial in 2023.

The evidence was overwhelming.

DNA from the scene.

DNA under Sarah’s fingernails.

Statistical certainty beyond comprehension.


The verdict:

Not guilty of premeditated murder.

But guilty of murder during an assault.

Guilty of second-degree murder.

And confirmed to be sexually motivated.


After more than three decades, justice—though delayed—was finally delivered.


But the story doesn’t end with a conviction.

Because what makes this case unforgettable isn’t just the crime.

It’s what it revealed:

How a single early release decision can change lives forever.

How predators can hide in plain sight for decades.

How technology can succeed where traditional investigations fail.

And how one small mistake—being early instead of late—can alter the course of everything.


Sarah Yarborough lived by one belief:

Seize the day.

And even though her days were taken, her story continues to reach millions—ensuring that she is never just a forgotten case file.

She is remembered.

She is heard.

And now—

She finally has justice.
