Two people were killed in separate Auburn Gresham neighborhood shootings that happened within a few hours of each other from late Friday into Saturday on the South Side.

About 3 a.m. Saturday, officers responding to a call of shots fired in the 8000 block of South Union found a person in an alley with a gunshot wound to the head, according to Chicago police, who said he was dead at the scene. The victim’s age was unknown.

Hours earlier, a man was fatally shot at an apartment complex just over a mile away.

About 10:40 p.m. Friday, officers responded to calls of a person shot at an apartment complex in the 8000 block of South Hermitage Avenue and found a man with a back wound in the hallway, Chicago police said. 

The 44-year-old was taken to Christ Medical Center in Oak Lawn, where he later died, authorities said.

No one from either shooting was in custody.
