A man was killed and another man wounded in a shooting Monday morning in the Riverdale neighborhood on the Far South Side.

The men were in an argument with another person about 11:40 a.m. in the 13100 block of South Langley, when the person pulled out a handgun and opened fire, according to Chicago Police.

The older man, identified as 26-year-old Maurice McKnight, suffered multiple gunshot wounds to the chest and side, and was pronounced dead at the scene at 12:08 p.m., according to police and the Cook County medical examiner’s office. McKnight lived in the 3700 block of South Wells.

The younger man, 20, was shot in the upper chest and left arm, and took himself to 131st and St. Lawrence, from where he called police. He was then taken to Christ Medical Center in Oak Lawn, where his condition was stabilized.
