No arrests have been made, but the police department said the case remained under "active investigation."
Jimmy Sherlock said the incident taught the six-year veteran cop a lesson.
"Anywhere you think you're safe, you're really not. I thought I was in a good area," he said.
"They could have easily killed me if they hit my artery," he said. "To kill me for a few things you could buy from a garage sale. . .There's no respect for life out there."
But Jimmy Sherlock said he's not going to change his lifestyle. "I'm not going to let them make me scared."
Police asked that anyone with information call Area Central detectives at 312-747-8484.
