An ambulance driver had an apparent medical emergency in a fiery crash in Pike County that injured two passengers.

Sgt. Jeremy J. Burkett of the Alabama Law Enforcement Agency said the incident happened at 3:35 p.m. Thursday on U.S. 231 near the 62 mile marker, about three miles south of Brundidge.

According to investigators, a 2014 Ford E-350 ambulance left the roadway, struck a ditch and a tree, and became engulfed in flames.

The ambulance driver, Robert L. Parrish, 70, of Cowarts, was driving when the medical emergency occurred. He was pronounced dead at the scene, and appears to have died from causes unrelated to the collision, authorities said.

Ruby D. Collins, 63, of Troy, the patient, and Hannah L. Sumner, 28, of Dothan, the on-board paramedic, were both injured. Collins was transported to Flowers Hospital in Dothan. Sumner was transported to Southeast Alabama Medical Center also located in Dothan.

Troopers with ALEA’s Highway Patrol Division continue to investigate.
