An autopsy was inclusive on what caused the death of a man found Friday on the front porch of a mobile home in White Township, but Indiana County coroner Michael Baker said he suspects drugs were involved.

Toxicology tests are pending, but the death of Jeffrey Wayne Stuller, 37, does not appear to be suspicious, the coroner said.

Mr. Stuller, who had no permanent address, was discovered Friday morning about 8 a.m. at the residence in Greene Valley Estates. He had been living temporarily at the residence, but he was not related to the occupant, Mr. Baker said.
