OAK LAWN, Ill. — A man is dead after being shot in the head outside of Advocate Christ Medical Center in Oak Lawn early Saturday morning.

According to police, a large group of individuals were near the emergency entrance of Advocate Christ in the 9400 Block of South Kilbourn Avenue around 2 a.m. when responding officers heard a single gunshot.

Brandon McGee, a 28-year-old man from Rockford, was found on the ground with a gunshot wound through his left eye, and a man, 36-year-old Marques Rose, was seen running away from the scene of the crime.

Police said witnesses told responding officers the man who ran away was the shooter. Rose was then apprehended shortly thereafter by police and taken into custody.

McGee was immediately brought into Advocate Christ’s emergency room for treatment after the shooting and was originally listed as being in critical condition with life-threatening injuries. He has since been pronounced dead, according to police.
