At least four people been killed and eight others wounded in shootings across Chicago over the weekend.

A 16-year-old boy was shot dead as he waited at a red light Sunday night in the Pilsen neighborhood on the Lower West Side, police said.

He was sitting in the driver’s seat at 9:45 p.m. in the 2000 block of South Canalport Avenue when a vehicle pulled up and someone inside fired shots, according to Chicago police.

The boy was shot in the head, and his vehicle careened into a wall underneath the Dan Ryan Expressway, police said. He was taken in critical condition to Stroger Hospital, where he died Monday morning. The Cook County medical examiner’s office has not confirmed the death, and no one is in custody.

At least four shell casings were scattered around his gray car near the intersection of Emerald and Canalport as officers investigated the scene. The vehicle’s windshield wipers were still swiping as police flashlights danced across the window.

A man was fatally shot Saturday night in the Austin neighborhood on the West Side.

Von Lindsey, 25, was sitting in a vehicle at 8 p.m. in the 5900 block of West Chicago Avenue when he was shot, according to Chicago police and the Cook County medical examiner’s office. He was struck multiple times and died at Stroger Hospital about half an hour later.

Lindsey’s only brother died earlier from gun violence, a woman identifying as his brother wrote on Facebook.

“I don’t even wanna do this Facebook” stuff, she wrote. “But losing both brothers to gun violence, this [stuff] hurt y’all. This one cuts deep. Being strong ain’t even a option right now.”

A friend wrote that “Von seemed to be the life of every party. What a beautiful man he was.”
