Computer equipment also was taken from the crematory during Wednesday's break-in. Sgt. Sammy Morris says police are investigating whether the hearse was stolen to haul the gear away. No arrests have been made.
Funeral director Jim Murphy says the corpse was unharmed. It was scheduled to be cremated Wednesday.
The Greenfield Crematory has apologized to the family. It says it was not unusual for the body to have been left in its vehicle, which was locked inside the building.
