MULLIN — A one-vehicle rollover accident Monday morning near Mullin took the life of a father and injured his three children as he drove them to school in Zephyr.

David Mangus, 34, of Mullin, was killed in the 7:30 a.m. accident, which happened 1.9 miles south of Mullin on FM 573, Department of Public Safety trooper Stephen Lankart said.

The 2007 Chevrolet extended-cab pickup Mangus was driving left the road and rolled over and hit a tree roof-first, Lankart said. He did not know what caused the pickup to leave the road.

Mangus’ three children – Dustin, a fourth grader, Sidney, a third grader, and John, a first grader – were taken by Mills County ambulance to Brownwood Regional Medical Center with non-life-threatening injuries, Lankart said, although Dustin was transferred to Cook Children’s Medical Center.

Zephyr superintendent David Whisenhunt said it is puzzling why Mangus, who he said was a careful driver, left a straight section of the road.

Staff and students in Zephyr have been following the details of the accident and the progress of the injured students, Whisenhunt said.

“Everybody just loves these little kids … it’s just a tough situation,” Whisenhunt said.
