Castaneda fell from the overpass to the street below. Highway patrol has yet to determine why the driver lost control.

An off-duty Arlington police officer witnessed the accident, called 911 and tried to help Castaneda.

The 17-year-old driver wasn’t injured and there were no signs of impairment at the scene, or that the driver struck Castaneda intentionally, police said.

Castaneda was a five-year veteran of the force.

He worked previously with the U.S. Coast Guard for eight years and Tarrant County Sheriff’s Department for six years.
