State Street was temporarily closed between Jackson and Van Buren as police investigated, and Red and Blue Line bypassed the Jackson stop for several hours after the shooting, but State Street has since reopened, and Red and Blue line trains are running normally again.

According to police, one of the men died at the scene after he was shot in the stomach and chest.

The other man was shot in the head and arm and remains in critical condition.

A 19-year-old woman was also shot and police told CBS 2 she was with the two men and may have not been the intended target.
