As the shooting incident unfolded, the typically quiet west side Kenosha Horizons subdivision was flooded with police, including officers in tactical gear.
About two hours after the initial police call, there was the sound of a loud boom at the scene — possibly the sound of a stun grenade — and tactical officers cleared the area.
Neighborhood resident Frank Ritacca said he saw the first police arriving shortly after 3 p.m. and followed them, speaking to neighbors who live near the scene.
“They saw the mother stumble out of the house,” he said. He said he saw police performing CPR on a second victim.
“There’s troopers with high-powered rifles at the end of the street,” Ritacca said. “This neighborhood is usually so quiet.”
Police closed off nearby streets as the Kenosha County Sheriff’s Department mobile command center set up on 111th Avenue and 66th Street.
School buses were diverted, and police officers escorted residents to the homes within the area where streets were closed.
Parents of students at Pleasant Prairie Elementary School and Mahone Middle School were alerted to the situation by Kenosha Unified School District officials.
The alert asked families living within a 1-mile radius of the incident to pick up their children at the schools.
“The students are safely in our buildings and our staff is prepared to stay until all affected students are picked up,” the message said.
