Officers fatally shot a person in suburban Joliet Tuesday evening, according to police.
Authorities said at around 6:30 p.m., officers responded to the 800 block of Second Avenue for a call that someone was threatening to shoot people.
Upon arrival, police said officers "encountered a white male subject in the street brandishing what appeared to be a black semiautomatic handgun" and when the person threatened the officers, they opened fire. Police did not say a weapon was recovered on the scene and did not respond to request for further clarification.
NBC 5 has not independently verified the reports of the incident from police.
Residents of the neighborhood said they heard more than a dozen gunshots and then immediately after saw officers performing CPR on a person on the ground.
Police said the person was taken to Silver Cross Hospital where he was pronounced dead. The Will County Coroner's Office did not immediately confirm the fatality and further details, including the person's age or identity, were not available.
One witness said she saw officers shoot a man who looked to be between the ages of 19 and 21, hearing more than a dozen gunshots as she took cover inside her home.
"He had a cell phone up and the police shot at him and hit the phone and the phone exploded," one woman said, noting that it was uniformed officers in two squad cars involved in the shooting, but afterwards many more arrived on scene.
The woman said bullets flew into her home, though no one inside was hurt.
"It went through my front window, went through my living room window, came all the way out of my bedroom window," she said. "It went through my bedroom wall, it hit my closet."
She and another neighbor both said they saw officers performing CPR on the person lying on the ground, which was also captured on cell phone video, immediately after hearing the gunshots.
Juana Alvarez said the shooting happened in front of her house and that she heard about eight shots before she later came outside.
"I don’t know if the guy came over here," she said. "But we did see a gun on the floor. But all I've seen was a guy on the floor, bleeding. The cops were on top of him, proceeding CPR on him."
"We got scared, we were really scared," she said. "I mean, I have kids. I threw them on the floor and then we immediately took them downstairs to the basement. And then when we seen outside, we've seen the cops doing the CPR on him, trying to save his life."
The officers involved were not injured in the incident but were taken to Saint Joseph Medical Center for evaluation, according to police.
Police said the scene was turned over to the Will-Grundy Major Crime Task Force for investigation. Investigators could be seen looking for shell casings at the scene overnight, with a backpack and clothing scattered on the ground.
