GREENVILLE, S.C. -- Greenville County authorities are investigating the death of a man whose body was found behind a house.

Authorities said the body of 54-year-old Billy Michael Patterson was found around midday Wednesday behind a home in the Judson community.

Chief Deputy Coroner Mike Ellis says he has ruled the death “suspicious” because there were signs of trauma on the body.

An autopsy was planned Thursday.

Ellis says he thinks Patterson died late Tuesday or early Wednesday.
