A man was killed Thursday afternoon in a domestic-related shooting in the Mount Greenwood neighborhood on the Far South Side.

Brandon Sutka, 26, was involved in a physical altercation about 3:15 p.m. in the 10700 block of South Central Park Avenue when someone pulled out a gun and shot him, according to Chicago police and the Cook County medical examiner’s office.

Sutka was pronounced dead at the scene at 4:12 p.m., authorities said. He lived in the same neighborhood.

An autopsy conducted Friday found Sutka died from a gunshot wound to his right shoulder, and his death was ruled a homicide, the medical examiner’s office said.

The shooter was taken into custody and later released after investigators determined they acted in self defense, police said.
