Officers found the man, who appeared to be in his 20’s, unconscious between two apartment buildings in the 700 block of West Briar around 2:10 a.m., police said.
The man was later pronounced dead at Illinois Masonic Medical Center.
Detectives believe the man may have accidentally fallen from the building’s roof, according to a source. His third-floor apartment window was found closed. Police were unable to find witnesses who could help them pinpoint the timing of the man's injuries.
