A 29-year-old man was killed Saturday in a shooting in South Chicago.

Malcolm Sabbs was standing on the sidewalk about 1:35 a.m. in the 8600 block of South Exchange Avenue when a group of males approached him on foot and unleashed gunfire, Chicago police and the Cook County medical examiner’s office said.

Sabbs was struck in the head and taken to the University of Chicago Medical Center in critical condition, authorities said. He was pronounced dead about 14 hours later.

The medical examiner’s office ruled his death a homicide, with an autopsy saying Sabbs died of multiple gunshot wounds.

Area South detectives are investigating.
