A Shenandoah County fire official has determined that a grill filled with hot coals in the back of a pickup truck started a blaze that destroyed the vehicle Sunday. A Maurertown man, his girlfriend and their two small children were traveling in a 2018 Ford F350 through Strasburg around 7 p.m., Assistant Fire Marshal Joseph Loving said Monday. Someone noticed flames coming from the bed of the truck and the driver pulled over on Crystal Lane in front of the Rite Aid store. The family escaped the vehicle unharmed, Loving said.
