Police found 25-year-old Jonathan Murray lifeless in the 6600 block of South Claremont Avenue at 4:22 p.m., less than a block from his home.
Three men were killed and nine others wounded in gun violence across the city since Monday afternoon, including two men who were found shot to death in West Pullman early Tuesday.
The teen was shot about 2 p.m. in the 6400 block of South Claremont Avenue in the Chicago Lawn neighborhood on the Southwest Side.
One man was killed and another was injured in a shooting at 71st Street and Western Avenue Monday night.
It started as a test drive, but within seconds a Chicago car salesman was knocked to the ground when a carjacker hit him with the car and drove away. It was the third in a string of carjackings at auto dealerships in the area in recent weeks.
