CHICAGO (STMW) — A 21-year-old man playing video games with his brother in a bedroom of a Humboldt Park apartment early Saturday died after bullets came through a window, authorities said.

Devon Greer, of south suburban Lansing, was in a bedroom of the apartment in the 3800 block of West Augusta Boulevard about 3:40 a.m. when he and his brother heard gunshots, authorities said.

Greer soon realized he had been struck in the back by the gunfire, police said. His brother apparently was not injured, according to an initial police report.

The shots had been fired from outside the front of the home and entered through a window, according to police.

Greer was taken in serious condition to Mount Sinai Hospital, where he died at 5:22 a.m., according to the Cook County Medical Examiner’s office.

No one was in custody as of Saturday night. Area North detectives are investigating.
