Excerpts from abc7chicago,com:

A decomposing body was found after a fire in an East Chatham apartment building early Monday morning. Authorities responded to the fire at around 1:20 a.m. in the 7900-block of South Greenwood Avenue and they found a body in a third floor apartment.

The body is that of a man and is now with the Cook County Medical Examiner’s Office for an autopsy.

Authorities have not said how the person was killed or how long the person was inside the apartment. His identity has not been released.
