The most recent shooting happened early Sunday in the Chatham neighborhood on the South Side.

A 20-year-old man walked into Jackson Park Hospital and Medical Center with a gunshot wound to the leg about 4:15 a.m., police said.

A shooting early Saturday injured four people — two men and a woman — in the Humboldt Park neighborhood on the West Side.

The four were in a vehicle traveling westbound in the 3300 block of West Beach Avenue about 2:20 a.m., when they heard shots ring out and realized they each had been struck, police said.

They then drove themselves to Norwegian-American Hospital, police said. The 19-year-old woman was shot in the left leg; an 18-year-old man was shot in the back; a 20-year-old man suffered gunshot wounds to both arms; and a third man, 21, was shot in the right shoulder, police said.

Police believe the shooting may have been gang-related.

At least 14 others were wounded in shootings across the city since Friday night. No one is in custody for any of the shootings as area detectives investigate.
