CINCINNATI (AP) — An 11-year-old boy was killed and five other people were injured in a shooting in Cincinnati, police said.

The shooting was reported just before 9:30 p.m. Friday in the West End and responders found six people with varying degrees of injuries, Cincinnati Police Chief Terri Theetge said. One was pronounced dead. Theetge said some of the victims were teenagers.

“This is absolutely unacceptable in our city – unacceptable that six people were shot in one incident on a Friday night,” she said.

Three victims were taken to Cincinnati Children’s Hospital Medical Center and two were taken to University of Cincinnati Hospital, police said. Cincinnati Children’s said Saturday that all three patients were in critical condition upon arrival. One patient was discharged overnight and the other two remained hospitalized in unchanged condition.

Cincinnati Mayor Aftab Pureval called it “a terrible tragedy,” adding, “Children were shot. At least one life was lost.”

“Our friends and neighbors are feeling unimaginable fear, trauma and anger,” Pureval said, pledging to “do everything we can to bring justice to this despicable, heartless violence.”

Theetge said she shared the anger of area residents over the violence.

“This happens too often,” she said. “People are resorting to gun violence instead of resolving disputes in a humane way. It is inhumane to pull out a firearm and shoot people recklessly.”
