When a needle on a highway was the trigger for a man’s death, Texas highway patrol says

The Texas Highway Patrol says it’s working with the U.S. Drug Enforcement Administration to investigate an overdose that took the life of a Texas highway guard.

The trooper who died in a February 2016 overdose at the Dallas-Fort Worth International Airport was among five members of the Texas Highway Guard who responded to a call about a man suspected of injecting fentanyl into a passenger’s syringe.

State troopers responded to the scene, and the driver of the vehicle was taken into custody, according to the Texas Department of Public Safety.

The driver’s name and address were not released by the department.

Authorities say the driver had taken fentanyl at an apartment complex in the town of Denton, near Dallas.

He was found dead on the highway.
