Illinois man shot in head after throwing can at driver, police say

CHICAGO, IL -- A 21-year-old man was shot in the head on Chicago's southwest side after an "altercation" with the 28-year-old man who shot him, police said.

Authorities said the younger man was standing on the corner of West 59th Street and South Pulaski Road around 12:50 a.m. Tuesday when he allegedly put up a gang sign and threw a can at the older man, who had stopped his red Chevrolet Malibu at the intersection.

The 28-year-old man pulled out a gun and fired at the 21-year-old man, investigators said. He was taken to Advocate Christ Medical Center with a gunshot wound to the head. He is listed in critical condition.

The driver allegedly took off, heading south. Officers arrested him less than 10 minutes away, near West 63rd and South Whipple streets.

Sources close to the investigation said the 28-year-old man is a security guard. Police have not confirmed this. Charges are pending against him.
