A boy was in critical condition Tuesday evening after he and three others were shot Tuesday evening in the Trumbull Park neighborhood on the Far South Side.

At 7:12 p.m., he was walking down a sidewalk with another 16-year-old boy, a 19-year-old man and a 21-year-old woman when they were struck by gunfire in the 10600 block of South Bensley Avenue, according to Chicago police. The shooter was heading east on 106th Street.

One 16-year-old boy suffered multiple gunshot wounds and was taken to the University of Chicago Medical Center in critical condition, police said.

The other boy was taken to the same hospital in serious-to-critical condition, according to Chicago police and the Chicago Fire Department. His condition has stabilized after he was shot in the lower right leg.

The adults were taken to Christ Medical Center in Oak Lawn, one in fair-to-serious condition and one in serious-to-critical condition, police and the fire department said. Both of their conditions have stabilized.

The 21-year-old woman was shot in the right hip and the 19-year-old was shot in the left elbow.

Area South detectives were investigating.
