By Cold Cases After Dark

Most people wake up early for ordinary reasons.

To get to work.

To catch a flight.

To make breakfast before the day begins.

On January 25, 2019, Elizabeth Barraza woke up before dawn to set up a garage sale in the driveway of her home in Tomball.

She was trying to make a little extra money for an anniversary trip with her husband.

Within minutes, she would be dead.

And seven years later, despite surveillance footage, a suspect vehicle, and a nationwide investigation, no one has been arrested.

A Woman Who Loved People More Than Things

Elizabeth known to friends and family as Liz was 29 years old.

She loved Star Wars. She loved Harry Potter (her and I would have been best friends). She volunteered, helped others, and was active in charity groups connected to the 501st Legion.

Friends described her as warm, funny, and generous.

She wasn’t known for drama.

She wasn’t known for enemies.

Which is why what happened next seemed impossible.

The Morning Everything Changed

It was still dark when Liz began setting up the garage sale in the driveway of her home on Cedar Walk Drive.

Her husband, Sergio, left for work shortly before 7 a.m.

Just minutes later, a dark-colored Nissan Frontier PRO-4X pulled up near the house.

A person wearing a disguise stepped out.

The suspect walked directly toward Liz.

Security cameras captured the encounter.

For a few seconds, the two appeared to speak.

Then the gun came out.

Four shots were fired at close range.

Liz collapsed in her driveway while the shooter calmly returned to the truck and drove away.

Investigators later revealed that the weapon was likely a revolver, meaning no shell casings were left behind. Nothing was stolen. The attack appeared planned and targeted. abc13.com +2

The Video That Should Have Solved the Case

One of the most frustrating aspects of this investigation is that the murder was caught on camera.

Detectives have released surveillance footage showing:

• The suspect approaching Liz.
• The shooting itself.
• The suspect fleeing.
• The suspect vehicle, believed to be a dark-colored Nissan Frontier PRO-4X crew cab.

Yet despite years of publicity, investigators have never publicly identified the killer.

Tips have poured in.

Thousands of hours have been spent reviewing leads.

The FBI and Texas Rangers have assisted in the investigation.

Still, the case remains unsolved.

A Family Still Waiting

Liz’s parents have become some of the strongest advocates for keeping the case alive.

They created a website dedicated to finding her killer and have spent years pushing for new leads and renewed public attention.

In recent interviews, her father has spoken openly about his fear that he may not live long enough to learn who murdered his daughter.

That is the cruelty of a cold case.

The victim’s life ends in a moment.

The family’s grief stretches across decades.

Theories Through a Criminal Justice Lens

Important: The following section is opinion and analysis, not established fact.

Theory 1: The Killer Was Watching the House

One detail that stands out to me is timing.

The shooter arrived only minutes after Sergio left for work.

That suggests one of two things:

• The killer already knew Sergio’s routine.
• The killer was actively watching the house that morning.

As a Criminal Justice major, I lean toward the second possibility. The precision of the timing feels less like coincidence and more like surveillance.

Theory 2: The Garage Sale Was the Opportunity, Not the Motive

Many people focus on the garage sale itself.

I think that’s backwards.

The garage sale may not have been the reason Liz was targeted—it may have been the reason she was vulnerable.

She was outside, alone, before sunrise, with her attention focused on setting up tables and items. A killer who already intended to attack her may have viewed that morning as the perfect opportunity.

Theory 3: The Disguise Was Designed for Recognition, Not Concealment

This is a theory I rarely see discussed.

Investigators have said the suspect appeared to be wearing a disguise. Most people assume that means the killer wanted to avoid identification.

But what if the disguise served another purpose?

If Liz knew the attacker personally, a disguise could have been intended to create just enough uncertainty to prevent immediate recognition by neighbors, cameras, or even Liz herself during those first few seconds.

In other words, the disguise may have been meant to delay recognition, not eliminate it.

Theory 4: The Return to the Scene Suggests Verification

Investigators have indicated the suspect may have circled back after the shooting. abc13.com +1

That behavior is significant.

In behavioral analysis, returning to the scene can indicate the offender was not merely escaping they were confirming the outcome.

That is often seen in highly personal crimes where the offender’s goal is the victim’s death, not intimidation or robbery.

Theory 5: The Killer Expected the Case to Go Cold

Here’s the theory that troubles me most.

The use of a revolver, the disguise, the rapid approach, and the immediate escape all suggest planning. But planning alone doesn’t explain the confidence.

I believe the offender may have known that without shell casings, without a clear face, and with a common vehicle type, investigators would struggle to identify them.

In other words, the killer may have committed the crime believing the evidence would never be enough.

The Question That Haunts This Case

What was said in those final seconds?

Security footage shows the suspect speaking to Liz before the shots were fired.

Was it a greeting?

A warning?

A name?

Did Liz realize who was standing in front of her?

That unanswered question is one of the most haunting parts of the entire investigation.

Remembering Liz

It’s easy to become fascinated by the mystery.

The truck.

The disguise.

The surveillance footage.

The theories.

But before Elizabeth Barraza became a headline, she was a daughter, a wife, a friend, and a woman who spent her time helping others.

She woke up that morning expecting to sell old belongings and plan a vacation.

Instead, her family was forced to plan a funeral.

Until the person who walked up that driveway is identified, this case remains one of the most chilling unsolved murders in modern Texas history.

And at Cold Cases After Dark, we will keep telling Liz’s story until someone finally speaks.
