Atlanta police and the DeKalb County Medical Examiner’s Office are working to determine what killed a man whose body was found early Tuesday in a sleeping bag along DeKalb Avenue.

The body was discovered about 12:30 a.m. inside a sleeping bag in a parking lot, Atlanta police spokeswoman Kim Jones said.

“There were no true indicators of criminality or cause of death,” Jones said.

The man’s identity has not been released.
