NORTH LAWNDALE — Activists will hold a vigil Tuesday for the 16-year-old shot and killed by police after an "armed confrontation" Monday night, officials said.

Around 7:40 p.m., officers on patrol in the 3400 block of West Grenshaw Street were trying to pull over a car they thought had been involved in a shooting when someone jumped out of the car and ran, according to a Chicago Police news release.

A brief chase led to an "armed encounter" between the person and the officer, and it ended with the officer fatally shooting the teen, police said.

The victim was identified as Pierre Loury, 16, of the 3600 block of West Grenshaw, according to the Cook County Medical Examiner's Office.

No officers were hurt, police said, and a gun was found at the scene.

Activists plan to hold a vigil for Loury and have criticized police, saying they "no longer accept the lack of accountability." The vigil will be held 7 p.m. Tuesday at 3436 W. Grenshaw St., where Loury was killed.

"We need to know why a 16-year-old child was murdered by the Chicago Police [Department] last night and why the department isn't transparent in their investigation of the shooting," activists wrote on the Facebook event page for the vigil.

The event is being hosted by Black Lives Matter. Dorothy Holmes, whose son, Ronnie, was shot and killed by police in October 2014, will speak at the vigil for Loury, as will Fred Hampton Jr., Amika Tendaji and other activists.

Activists have also taken to Twitter and Facebook, using the hashtag #Justice4Pierre to spread awareness of Loury's death and the vigil.

“My baby is gone,” Tambrasha Hudson, Loury's mom, told CBS2. “He was loving, caring. He helped me a lot with his other siblings.”

Hudson disputed police accounts of the incident, telling CBS2 her son, the oldest of six, didn't have a gun.

“We just want justice, that’s it; point blank, period," Vantrese Frazier, Loury's stepfather, told CBS2. "We don’t want no money. We don’t want nothing. We want the corruption to stop."

Per the new citywide policy announced in December, the officer who fatally shot Loury will automatically be placed on administrative leave for 30 days.

The shooting is being investigated by the Independent Police Review Authority, police said.
