Two people were killed and four others injured in a two-vehicle crash in Ector County on Friday night. According to the Texas Department of Public Safety, 61-year-old Juan Manuel Nunez-Quiroz was driving a 2019 Chevrolet 2500 southbound on Knox Avenue when he allegedly failed to stop at a stop sign at the intersection of W. University. His vehicle was reportedly struck by a 2012 GMC Yukon traveling westbound on FM 2020. Nunez-Quiroz and GMC passenger Tyson Cooper Avery, 32, were both pronounced dead at the scene. Three minors and 34-year-old Rachel Avery were also injured in the crash.

When an alleged stop sign violation results in multiple fatalities and injuries, investigators must carefully determine how and why the crash occurred. The cause may seem straightforward, but it’s important to confirm whether any contributing circumstances were present.

Could Distraction or Fatigue Have Played a Role?

While the report states Nunez-Quiroz allegedly ran the stop sign, investigators will need to consider whether distraction or fatigue was involved. Using a phone, adjusting the radio, or simply being overly tired can cause a driver to miss traffic control devices. Reviewing phone records, interviewing witnesses, and checking the driver’s activities earlier in the day could shed light on whether his attention was compromised.

Was There a Possible Vehicle Issue?

Investigators may also need to rule out the possibility of a mechanical failure. Brake problems, steering issues, or malfunctioning lights could affect a driver’s ability to respond to an intersection safely. Examining the Chevrolet’s braking system, tires, and electrical components will be necessary to determine whether a defect or maintenance problem contributed to the collision.

What Evidence Should Be Collected?

To build a full picture, investigators should examine physical evidence at the scene, such as skid marks, impact points, and debris fields. Vehicle data recorders can provide speed, braking, and throttle input leading up to the impact. Surveillance or traffic cameras in the area may also confirm whether the Chevrolet failed to stop or if another factor came into play.

Why Investigations Like This Are Essential

Whenever a crash leads to death and injury, the facts must be carefully established. A thorough investigation ensures that all potential causes, including driver behavior, vehicle condition, or other contributing factors, are considered.
