Expert Legal Analysis: The Harlingen Expressway Crash and the Pursuit of Justice for David Zapata
The impact of an 80,000-pound commercial vehicle or a high-speed passenger car on the Harlingen Expressway doesn’t just damage steel; it destroys families. On July 8, 2025, the community of Harlingen and Cameron County witnessed a tragedy that underscores the extreme dangers faced by those who work on our Texas roads. David Zapata, a 46-year-old tow truck driver and dedicated professional, was fatally struck while performing his duties on the expressway.
The man accused in this case, Cristobal Stephan Garzez, now faces a series of serious charges: intoxication manslaughter with a vehicle, manslaughter, and possession of a controlled substance. As legal analysts and trial attorneys with over 27 years of experience, we look at the facts of this incident—the fentanyl found in the vehicle, the blood spatter evidence, and the allegation that the driver fled the scene because he was “scared”—and we see a roadmap for a complex, high-stakes litigation effort aimed at maximum accountability.
If you have been affected by a similar tragedy, you need more than a lawyer; you need a legal emergency team. Call Attorney911 at 1-888-ATTY-911 for a free consultation.
The Reality of Roadway Worker Fatalities in Cameron County
Harlingen sits at a critical junction in the Rio Grande Valley. The Expressway (I-2 / I-69E corridor) handles massive volumes of both local commuter traffic and heavy commercial freight moving toward the Port of Brownsville and the border. In 2024, Cameron County recorded 8,233 total crashes, resulting in 41 fatalities. David Zapata’s death is not just a statistic; it is a reminder that for roadway workers, the “Move Over” law is a matter of life and death.
Texas law is clear: drivers must move over a lane or slow down significantly when passing emergency vehicles, including tow trucks with blue or amber lights. When a driver like Cristobal Stephan Garzez fails to do so—especially while allegedly under the influence of a controlled substance like fentanyl—the results are almost always catastrophic.
At Attorney911, we understand the specific physics and legal requirements of these cases. Our managing partner, Ralph Manginello, has spent 27+ years in Texas courtrooms holding negligent parties accountable. Our team includes a former insurance defense attorney, Lupe Peña, who used to work for the very companies that now try to minimize these claims. We know their playbook because we helped write it, and now we use that insider knowledge to fight for victims like the Zapata family.
Fentanyl and Intoxication Manslaughter: Breaking Down the Charges
The indictment against Garzez is particularly harrowing. Law enforcement reportedly found a small bag containing 1.26 grams of fentanyl in his vehicle. Fentanyl is a potent synthetic opioid that can cause extreme impairment, including slowed reaction times and loss of consciousness.
In Texas, Intoxication Manslaughter (Texas Penal Code § 49.08) is a second-degree felony. It occurs when a person operates a motor vehicle in a public place while intoxicated and, by reason of that intoxication, causes the death of another by accident or mistake.
The Felony Exception to Punitive Damage Caps
One of the most critical aspects of this case from a civil litigation perspective is the nature of the criminal charges. Under Texas Civil Practice & Remedies Code § 41.008, there are typically caps on punitive (exemplary) damages. However, these caps are REMOVED if the defendant’s conduct falls under certain felony “cap-busting” crimes, including intoxication manslaughter.
If a jury in Cameron County finds that a driver’s gross negligence was fueled by felony-level drug impairment, there is NO statutory limit on the punitive damages they can award. This is designed to punish the offender and deter others from similar behavior.
Our firm has a history of handling these high-exposure cases. As we often state, “Our firm is one of the few firms in Texas to be involved in BP explosion litigation.” That $2.1 billion case involved massive corporate negligence and loss of life. We bring that same level of intensity to every roadway fatality case we handle in Harlingen and beyond.
The “Hit and Run” Factor: Fleeing the Scene
Garzez allegedly fled the scene of the crash, telling officers later that he was “scared.” In the eyes of the law and a jury, fleeing the scene of a fatal accident is an aggravating factor that speaks to a “conscious indifference” for human life.
From an evidentiary standpoint, the “scared” defense rarely holds up when physical evidence is present. Reports indicate there was blood spatter on the passenger door of Garzez’s vehicle at the time of his arrest. This type of forensic evidence is undeniable and creates a powerful narrative for the prosecution and for any subsequent civil wrongful death claim.

Proving Liability in Roadway Worker Wrecks
When a tow truck driver is killed on the job, we don’t just look at the driver who hit them. We look at the entire collection stack of liable parties:
- The Individual Driver: Cristobal Stephan Garzez is directly liable for his alleged intoxication and failure to control speed.
- The Vehicle Owner: If the vehicle Garzez was driving belonged to someone else, we investigate “Negligent Entrustment.” Did the owner know he was a risk?
- The Dram Shop / Provider: While fentanyl is an illegal controlled substance, if Garzez had also been overserved alcohol at a Harlingen bar or restaurant, that establishment may be liable under the Texas Dram Shop Act.
- Employment Status: Was Garzez working at the time? If he was on the clock for a company, that company is vicariously liable for his actions under the doctrine of respondeat superior.
At Attorney911, we are relentless in our investigation. As client Jamin Marroquin shared: “Mr. Manginello guided me through the whole process with great expertise…tenacious, accessible, and determined throughout the 19 months.”
The Economic Impact of a Wrongful Death in Harlingen
David Zapata was 46 years old—a man in the prime of his working life. When a family loses a provider, the damages are extensive and must be calculated with precision. We look at:
- Lost Earning Capacity: The income Zapata would have earned over the remainder of his career.
- Loss of Companionship and Society: The intangible but profound loss felt by his spouse, children, and parents.
- Mental Anguish: The emotional pain of losing a loved one in such a violent, preventable manner.
- Medical and Funeral Expenses: The immediate financial burdens placed on the family.
Our documented results prove our capability in these matters. “At Attorney911, our personal injury attorneys have helped numerous injured individuals and families facing trucking-related wrongful death cases recover millions of dollars in compensation.” (Every case is unique, and past results do not guarantee future outcomes.)
Why the Trial Date Delay Matters
The trial for Garzez was recently rescheduled from April 2026 to May 11, 2026, to allow the defense to review body camera footage and cell phone evidence. In our 27+ years of practice, we know that digital evidence is often the “silent witness” that wins cases.
Cell phone records can prove distraction or help establish a timeline of where the defendant was—possibly at a bar or a location where he obtained the fentanyl—prior to the crash. Body camera footage captures the defendant’s immediate demeanor, statements, and level of apparent impairment.
We move fast to preserve this evidence. We send “spoliation letters” within 24 hours of being retained to ensure that surveillance footage from businesses along the Harlingen Expressway isn’t overwritten. Most systems delete footage every 7 to 30 days. If you don’t have a lawyer who moves quickly, that evidence is gone forever.
Attorney911’s Insurance Defense Advantage
Most personal injury lawyers have only seen one side of the table. Lupe Peña spent years at a national defense firm. “Lupe Peña worked for a number of years at a national defense firm, learning firsthand how large insurance companies value claims.”
This is our “Nuclear Advantage.” When an insurance company tries to argue that David Zapata was at fault for his own death because of where he was standing on the expressway, Lupe knows exactly how they’re building that argument. He used to make those same arguments for the other side. Now, he uses that insight to dismantle their defenses before they can even present them to a Cameron County jury.
As client Tracey White noted: “She had received a offer but she told me to give her one more week because she knew she could get a better offer.” We don’t accept lowball offers. We prepare every case as if it’s going to trial.
Our Track Record of Multi-Million Dollar Recoveries
We don’t just talk about fighting; we have the receipts. Our firm focuses on catastrophic injuries and wrongful deaths because we have the resources to take on big defendants.
- Brain Injury Success: “Multi-million dollar settlement for client who suffered brain injury with vision loss when log dropped on him at logging company.”

Frequently Asked Questions About Texas Roadway Accidents
What is the “Move Over” Law in Texas?
Texas Transportation Code § 545.157 requires drivers to vacate the lane closest to stationary emergency vehicles, including tow trucks, or slow to a speed that is 20 mph less than the posted limit. Failure to do so that results in a death is a serious criminal offense and evidence of gross negligence in a civil suit.
Can I sue for a hit-and-run in Harlingen?
Yes. If the driver is identified, you can pursue their liability insurance and punitive damages. If they are NOT identified, you can still recover through your own Uninsured Motorist (UM) coverage. Many people don’t realize their own policy protects them in these scenarios. Learn more in our video “Uninsured & Underinsured Motorists” at https://www.youtube.com/watch?v=kWcNFyb-Yq8.
How do I prove the driver was on drugs?
We subpoena toxicology reports, police body cam footage, and “black box” data from the vehicle. In the Harlingen case involving Cristobal Stephan Garzez, the discovery of fentanyl in the vehicle is a primary piece of evidence that our investigators would use to establish impairment.
What if another lawyer dropped my case?
We frequently take cases that other firms find “too difficult” or “too small.” As Greg Garcia shared: “In the beginning I had another attorney but he dropped my case although Mangiello law firm were able to help me out.” We have the experience and the “beast” mentality needed for complex Harlingen Expressway crashes.
Do I need a lawyer if the insurance company is being “nice”?
The insurance adjuster’s job is to save their company money. They may seem helpful while they try to get you to sign a release for a fraction of what your case is worth. Lupe Peña knows their tactics. “Lupe understands claim valuation—he calculated them himself.” Don’t sign anything until you call 1-888-ATTY-911.

His fellow tow truck drivers have already paid their respects, but the true measure of respect is accountability in a court of law.
