I heard what sounded like rapid gunshots last night and looked for the story today.via Chicago Tribune):
Authorities charged a 16-year-old boy after an off-duty Chicago police officer saw him shoot at a vehicle early Saturday in the South Loop neighborhood, police said.
The boy, whose name is being withheld because he is a juvenile, was charged with a felony count of aggravated discharge of a firearm at a vehicle and a felony count of aggravated unlawful use of a weapon by a minor. He was also cited with a misdemeanor count of aggravated assault of a peace officer, according to a news release from the Chicago Police Department.
The off-duty officer saw the boy run after a moving vehicle and shoot at it in the 1200 block of South Wabash Avenue around 12:40 a.m., according to police.
