Stevens was standing between two sets of tires on the long, oversized trailer when it unexpectedly began to roll. She tried to get out of the way but fell, according to the sheriff's office. Stevens suffered severe head and upper body injuries when she was run over by the trailer. The incident happened when brakes on the trailer were released without the brakes on the semi being set, the sheriff's office said.
The truck driver apparently worked for “East Coast Specialized Hauling, of Portsmouth, Va., was cited for parking a vehicle without setting the brakes”.
