An 86-year-old woman was killed Sunday afternoon in a freak accident in which she was run over by her own vehicle in the parking lot of a Bowie church, authorities said.

Marie Surowics, of Bowie, had apparently failed to put her vehicle in park before getting out of it at St. Edward’s Catholic church on Mitchellville Road just before 11:30 a.m. Sunday, according to a Bowie police report. The vehicle drifted backward, its open driver’s side door knocking Surowics to the ground, police said. She was then run over by the still drifting vehicle, police said.

Police said Surowics, of Bowie, was transported to a nearby hospital, where she was pronounced dead.
