CHICAGO (WLS) — Chicago police said investigators are questioning two people of interest after a 67-year-old man was gunned down near the United Center in broad daylight on Tuesday.

Police said the shooting happened in front of a Near West Side residential building near West Madison and South Leavitt streets just before 1 p.m.

Two armed suspects approached the man on the relatively busy street, just steps from a fire house and a public library, before taking out handguns and firing shots, police said.

A nearby resident, Julie Losch, said there was at least a handful of shots fired.

“I just heard four or five gunshots, and I walked out onto my balcony, and then I saw the police were immediately there. Took a minute for the ambulances to get there,” Losch said.

The shooting prompted a large police response, in part because there was initially an emergency call to assist responding officers, ABC7 is told.

Whether officers were nearby when the shooting happened was not immediately clear, but no officers were injured in the shooting.

Witnesses said first responders performed CPR on the victim, who was shot in the head. But the man was transported to Stroger Hospital, where he was pronounced dead. His identity was not immediately released.

“There’s people going to work, walking around. There’s a couple schools down the block, you know, a lot of families walking their kids, so yeah, it’s kind of disturbing,” said neighborhood resident Mike Ramirez. “It’s just concerning that, especially during daylight, you know, anything can happen.”

Police remained on the scene until about 4 p.m. Officials cordoned off a long stretch of Madison Street between Leavitt Street and Hoyne Avenue for hours.

Area detectives are investigating. Police did not immediately offer a motive for the shooting or release more details about what led to the gunfire.
