Four children between the ages of 4 and 18 died Monday when a vehicle was planted into a building that housed an after-school program in the small central Illinois town of Chatham, state police said.

Illinois state police said they were summoned to school camps at Ynot Ynot summer outdoors and 301 Breckenridge Rd. In Chatham

State police said the car was ploughing outside the building and hitting many people inside. The vehicle passes through the wall opposite the building.

Police said several injured people were taken to a local hospital by ambulance and a lifeguard took a helicopter to a local hospital.

The police aid driver was not injured in the crash and was taken to the hospital for evaluation.

Illinois Governor JB Pritzker said his administration is closely monitoring the situation.

"As we continue to learn more, follow the guidance of all local authorities. Tonight we wrap our weapons in the community when we receive the latest news about the situation."

Illinois Sen. Doris Turner (D-Springfield), who represents the region, issued a statement:

“When we send our kids down in the morning, we should always believe that they will be safely home at the end of the day. For some families, today’s beliefs have been shaken after the tragedy of Chatham Ynot.

"I'm heartbroken - there's actually no words that explain the feeling of the Chatham community and will feel it over the course of days, weeks and months. I want to thank the first responders, law enforcement and volunteers. My office and I'm ready to help in any way. I've been in touch with local authorities and will be relevant along with the relevant information."

Chatham Village Trustee Kristen Chiaro posted on Facebook that Chatham Baptist Church will be a unity for families with children in the center. Near the scene, Walnut Street between Park Street and Gordon Avenue closed traffic.

Chatham is about 12 miles south of Springfield, Sangamon County. Don't confuse it with the Chicago community on the south side of Chatham.

An investigation into the incident continued Monday night.
