The older man, identified as Justin M. Banks of Hebron, Ind., was found unresponsive on the ground and pronounced dead at the scene, according to police and the Cook County medical examiner’s office.

The younger man was found in the driver’s seat of a bullet-riddled pickup and taken to Mount Sinai Hospital, where he later died, police said. His name was not being released Monday morning pending notification of his family.

The 54-year-old woman was shot in the left leg and taken to Saint Anthony Hospital, where her condition stabilized, police said.

On Sunday morning, an off-duty Oak Park police officer was shot on Chicago’s Far South Side. The shooting happened in the 300 block of West 103rd Place at 5:13 a.m., police said.

The 57-year-old officer was getting out of his personal vehicle in the 300 block of West 103rd Place at 5:13 a.m. when he was approached by two males, police said. One of them fired shots at the officer, striking him in the arm and leg, police said. The officer returned fire and shot one of the suspects.

The off-duty officer was taken to Christ Medical Center in Oak Lawn, where he was in serious condition.

A few minutes later, responding Chicago officers found two “males of interest” in the 9900 block of South Princeton, police said. One of them had a recent gunshot wound and was also taken to Christ in serious condition. They were both in police custody but no charges had been filed as of Monday morning.

The most recent nonfatal shooting left a 16-year-old boy injured in the West Side Austin neighborhood Sunday evening.

He was shot in the leg about 6 p.m. in the 5500 block of West Quincy and taken to Stroger Hospital, where his condition stabilized, police said. Further details weren’t immediately available.

At least 25 others have been injured in shootings since Friday afternoon.

Additionally, a man suffered a possible graze wound to his head Sunday night when shots were fired at his car while he was driving in Pilsen.

The 21-year-old was driving in the 1600 block of South Loomis about 8:40 p.m. when someone fired shots from another vehicle, police said.

He drove himself to Stroger Hospital, where he was treated for a possible graze wound to the head. Police said the wound is very minor, and investigators are working to determine if he was actually struck by a bullet, or cut by glass fragments during a shooting.
