CHICAGO (CBS) — Twenty-two people were shot in Chicago on Monday, including 13 people shot in a span of one hour. Two people were killed, and the surviving victims included an 11-year-old boy and a 13-year-old boy.

The most recent shooting left one man dead and three other people wounded late Monday night in the West Pullman neighborhood. Police said, at about 10:50 p.m., three people were standing outside near 123rd and Yale, when a 19-year-old man opened fire from a nearby gangway, shooting three people. An unknown person returned fire, hitting the gunman in the face and chest.

The 19-year-old gunman later was pronounced dead at Advocate Christ Medical Center in Oak Lawn.

A 13-year-old boy was shot in the arm, and was being treated at Comer Children’s Hospital, where his condition was stabilized. An 18-year-old woman was shot in the thigh, and a 16-year-old boy was shot in the foot. Both were taken to Christ, where their conditions were stabilized.

About five minutes before that shooting, six people were shot in an attack in the Bronzeville neighborhood. Police said the victims were standing in Ellis Park near 37th and Vincennes around 10:45 p.m., when an unknown person began shooting.

None of the victims’ injuries was considered life-threatening. Four were being treated at the University of Chicago trauma center; including a 27-year-old man shot in the leg, a 24-year-old man shot in the ankle, a 20-year-old man shot in the hip and legs, and a 22-year-old man shot in the ankle. A 19-year-old man who was shot in the hip and arm was taken to Northwestern Memorial Hospital, and a 15-year-old boy who was shot in the ankle was taken to Mercy Hospital and Medical Center.
