Police are questioning a person of interest in connection with the attempted robbery of an off-duty Cook County Sheriff’s sergeant who shot and killed one of three people who tried to rob him Monday night on the Far South Side.
Police were questioning the individual Wednesday evening, police News Affairs Officer Veejay Zala said.
About 9:55 p.m. Monday, three males tried to rob the sergeant as he was pumping gas at a Citgo in the 700 block of East 103rd Street, according to Chicago Police and Cook County Sheriff’s spokesman Ben Breit.
The three demanded the sergeant’s wallet, which he gave to them. One of the suspects then pulled out a handgun and aimed it straight at the sergeant, according to Chicago Police. The sergeant pulled out his own gun and shot the male in the head, killing him.
Deonta Mackey, 16, of the 900 block of East 104th Street, was pronounced dead at the scene at 10:08 p.m., according to the Cook County Medical Examiner’s office. An autopsy Tuesday found he died of multiple gunshot wounds and his death was ruled a homicide.
The two other males ran off, police said.
Area South detectives are investigating.
