A 1995 Ford F-150, possibly left without its parking brake engaged, was the cause of two accidents Thursday — one injuring its owner and the other damaging a fence.

Police Chief Clinton Jeffrey said Chester A. Brown, 78, was gassing up his pickup at Casey’s General Store in Marion at 12:45 p.m. when the pickup started rolling down a slope toward an alley.

Brown tried to jump back into the truck and put it in park, Jeffrey said, but he fell and gashed his head on the parking lot.

The pickup continued rolling, going across the alley and into a privacy fence at That One Place.

“It hit the fence and knocked part of it down,” Jeffrey said.

The county ambulance director examined Brown, but he declined to be taken to a hospital.
