Beckley police tell media outlets the hearse's driver left the vehicle's door ajar and the engine running outside a local funeral Tuesday while he went to unlock the door to the building.
Angela Dehart of Beaver is accused of taking the hearse and driving it home. Police found the hearse and the body a couple hours later.
Police say the 23-year-old Dehart told investigators she and another person had been in the area in another vehicle. She got out of that vehicle and took the hearse.
DeHart faces charges of grand larceny and displacement of a body.
There was no telephone listing for Dehart in the Beaver area.
