A 20-year-old Culpeper woman was killed Friday morning after riding on a king-size mattress, which was unsecured on the top of a 2006 Chevrolet Express Van in Haymarket.
The incident happened at Bent Grass Drive and Waverly Farm Drive at 6:42 a.m.
The mattress had been placed on top of a ladder rack, he said.
Speed and alcohol were not factors in the incident, Probus said. The van’s driver is a 41-year-old Culpeper woman. Charges are pending.
