A Clayton County man found dead in the grass late Saturday in a downtown neighborhood had been shot to death, Atlanta police said Sunday.

The 37-year-old was found around 10:45 p.m. in the 200 block of Walker Street in Castleberry Hill, according to Officer Kim Jones. He was identified as Joe Frierson IV, according to the Fulton County Medical Examiner’s office.

Investigators have not determined a motive or any suspects, Jones said.

Police initially responded to a report of an injured person on Peters Street, near Fair Street, but they were unable to locate anyone. While investigating, officers found Frierson’s body in the grass and notified homicide detectives, Jones said.

The death remains under investigation.
