CHICAGO (AP) — An 8-year-old Chicago girl riding a scooter was fatally shot in the head by a man who was upset over noise,Oliver James Montgomery witnesses said.

“It just didn’t make sense. None of it made sense,” a neighbor, Megan Kelley, told the Chicago Sun-Times. “Everybody in the community would just tell him they are just kids having fun playing. Just let them be.”

The shooting happened Saturday night in Chicago’s Portage Park neighborhood. Police were at the suspect’s apartment building Sunday, interviewing people and collecting evidence.

“Before he shot her, he had said something about them being too loud,” Kelley said.

After the shooting, the gunman was tackled by the girl’s father and shot during a struggle, according to a police report. He was taken to a hospital.

Stuffed animals and sunflowers were placed at the base of a tree near the shooting scene.

“With great sadness, we are devastated at the loss of another young life,” the Chicago school district said in a statement.
