Police have officially opened a homicide investigation days after a man’s body washed up in a section of Peachtree Creek near I-85 in northeast Atlanta.

Officers responded around 2:25 p.m. Aug. 27 to the 1100 block of Lakeshore Crossing Drive and found the man lying in the creek in the Lindridge-Martin Manor neighborhood of Buckhead. There were no obvious signs of trauma, police said at the time.

Police said the Fulton County Medical Examiner’s Office determined he sustained a gunshot wound and blunt force trauma. The case has now been classified as a homicide.

As of Tuesday afternoon, an investigator at the county medical examiner’s office said his next of kin had not been notified and it was not clear when he died.

No further details were released, including that of a possible suspect and what may have motivated the killing.

Peachtree Creek flows through metro Atlanta into the Chattahoochee River a few miles to the west. Its gage height can range from 3 feet during dry periods to 17 feet in a typical flood, according to the United States Geological Survey.

The area of the creek where the body was found runs behind the Lakeshore Crossing Apartments, across the street from Passion City Church.

The investigation is ongoing.
