Callahan County, TX (May 16, 2026) – Two men, including an Abilene firefighter, died early Friday morning in an ATV crash on Highway 36 near County Road 228 in Callahan County.
Investigators said the collision occurred around 1 a.m. on May 15, when a Polaris Ranger side-by-side entered the highway from a field west of the roadway and traveled southbound. Authorities said the ATV was then struck from behind by a southbound 2020 Toyota Corolla.
Officials identified the ATV driver as 31-year-old Hunter Blake Patterson of Abilene. Patterson served as a firefighter in Abilene. The passenger was identified as 29-year-old Brett Cole Underwood of Clyde.
Authorities said both men were ejected from the ATV during the collision and died at the scene. Investigators reported that the side-by-side later caught fire following the crash.
The driver of the Toyota Corolla, identified as 42-year-old Alfonso Martinez IV of Royse City, suffered injuries and was taken to Hendrick Medical Center North before being airlifted to UMC Lubbock for additional treatment.
Investigators stated that neither Patterson nor Underwood was wearing a seat belt at the time of the crash. Officials also noted that weather conditions were clear and the roadway was dry.
Authorities continue to investigate the cause of the crash, and more details will be released as soon as they become available.
We extend our sincere condolences to the families of Patterson and Underwood
What Risks Are Common in ATV Crashes on Public Roadways?
ATVs and side-by-side vehicles are designed primarily for off-road use, and crashes involving these vehicles on highways can lead to severe injuries. Their smaller size, lower visibility, and limited protection for occupants can increase the risk of ejection during a collision.
Investigators often review roadway entry points, lighting conditions, and vehicle speed when examining ATV crashes on public roads. Seat belt usage is also commonly evaluated because restraints can reduce the chance of occupants being thrown from the vehicle. In rear-impact crashes, visibility and reaction time may become important factors, especially during overnight hours. Vehicle fires after impact can also complicate rescue efforts and increase the severity of injuries in high-force collisions.
