A man was killed and two other people were wounded Wednesday in a drive-by in South Shore on the South Side.

About 4 a.m., a 26-year-old woman was sitting in the backseat of a vehicle in the 7800 block of South Essex Avenue while two men, 26 and 30, stood around it, Chicago police said. A dark-colored vehicle drove by and someone inside opened fire on the group.

The 30-year-old man was hit in the arm and the 26-year-old woman was shot in the leg, police said.

Kenneth Summers, 26, was struck in the head, police and the Cook County medical examiner’s office said. An autopsy Thursday found he died of multiple gunshot wounds and his death was ruled a homicide.

They all were rushed to the University of Chicago Medical Center where Summers was pronounced dead, authorities said. The 30-year-old man and 26-year-old woman had their conditions stabilized.

One man, who declined to be identified, said he lives on the same block and ran outside after he heard the gunshots and subsequent screams. According to him, the ambulance took about 10 minutes to get to the scene.

That man didn’t personally know the 26-year-old who was killed but said he “knew of him.”

Area South detectives are investigating the shooting.
