Four men were shot in Chicago between about 8:45 and 10:45 p.m. on Friday, according to police.

One of the men, 31, died after he was shot by two people who approached him on foot, according to a release from the Chicago Police Department.

He was standing on a sidewalk outside his home in the 5800 block of South Fairfield Avenue in the Gage Park neighborhood about 10:35 p.m. when the two started shooting, police said.

He was struck twice in the left armpit and was pronounced dead at 11:27 p.m. at Mount Sinai Hospital. The Cook County medical examiner's office identified the victim as Ruben Colunga, 31.

About 20 minutes earlier, two men, both aged 25, were shot as they emerged from an alley in the 3100 block of West Pershing Road in the Brighton Park neighborhood, police said.

One man was shot in the chest and back and the other was shot in the upper right leg. Both were taken to Mount Sinai Hospital, the first in stable condition and the second in good condition.

Police said the shooting appeared to be gang-related. The shooters exited a light-colored vehicle before firing shots at the two, police said.

Earlier, an 18-year-old man was shot about 8:45 p.m. on the Far South Side, Chicago police said. He was shot in the 200 block of East 111th Street, Chicago Police News Affairs Officer Hector Alfaro said, citing preliminary reports. That's near Palmer Park.

He suffered an in-and-out gunshot wound to the thigh, Alfaro said.

The teen was described as "uncooperative" by police and gave a second address of where he was shot – in Ada Park, on the 11200 block of South Ada Street, also in the Roseland neighborhood.

His condition and other circumstances surrounding the shooting weren't immediately available.

He was taken to Roseland Community Hospital.
