A decomposed body found Thursday in a Southwest Side Marquette Park dumpster had been fatally shot in the head, an autopsy has ruled.

Officers the body about 12:30 p.m. after a neighbor had called 911 about a foul odor in the 6800 block of South Artesian, according to Chicago Police. The body was that of a male, whose age and identification haven’t been determined.

An autopsy Friday found he died of multiple gunshot wounds to the head, according to the Cook County Medical Examiner’s Office. The death was ruled a homicide.

Police initially said the body had been dismembered, but a spokeswoman for the medical examiner’s office said it had decomposed and was not dismembered.
