A powerful wind gust blew off a section of a pizza shop roof, killing a passing motorist when it slammed into his car, state police said Wednesday.

Michael Brandon Hess, 19, of Glade Springs was traveling on Route 58 Tuesday evening when the roof and possibly remnants of an air conditioning unit landed on his Ford Mustang, Sgt. Michael Conroy said.

Conroy said he suspects the roof was ripped off by a microburst, caused by air descending from a thunderstorm. Scattered damage to some homes was also reported in this southwest Virginia community.

Hess was driving alone and was pronounced dead at the scene. There were no reports of injuries in the pizza shop, Conroy said.
