The man found dead in Whitewater Creek on Tuesday night has been identified as 63-year-old Michael Hughes of Marietta, according to the Fulton County Medical Examiner’s office.

A woman walking her dog spotted Hughes’ body lying face-down in the 4000 block of Whitewater Creek Road, Channel 2 Action News reported. The creek feeds into the Chattahoochee River.

Police and fire crews were called in just before 7:30 p.m., but it took them hours to recover the body as the area was tough for emergency responders to reach.

An investigator with the Medical Examiner’s office said Thursday they are still trying to determine how the man died. It is not known how he ended up in the water.
