Police say the workers were looking for downed trees when they saw what they thought was a brush fire Monday afternoon at Hautman Park in Upper Providence Township, Delaware County.
The workers soon realized it was body on fire.
An autopsy is planned to determine the man's cause of death. A wallet found about 30 yards from the scene but police are not releasing the name on the identification found inside.
Upper Providence police Sgt. Michael Langdale says the park is used mostly by people taking strolls or walking their dogs.
