CHATHAM, Ill.>> Residents of a small central Illinois city on Tuesday mourned the loss of three children and a teenager killed in a startling crash in which a car barreled through a building used for a popular after-school camp. Authorities said it didn’t appear to be a targeted attack.

The car left a road, crossed a field and smashed into the side of the building in Chatham on Monday afternoon, according to Illinois State Police. It traveled through the building, striking numerous people before exiting the other side. Six children were hospitalized, including one in critical condition.

The Sangamon County coroner identified the victims as 18-year-old Rylee Britton of Springfield and three Chatham children: Ainsley Johnson, 8, and Kathryn Corley and Alma Buhnerkempe, both 7.

“This is just devastating,” said Jennifer Walston, 43, as she and her three daughters left flowers and a stuffed animal at the crash site. Plywood covered the hole where the car had crashed into the building used by Youth Needing Other Things Outdoors.

As details about the investigation emerged, people in the community of nearly 15,000 outside the Illinois capital city of Springfield found ways to grieve and comfort each other.

Schools switched to online learning, and churches held prayer services. City leaders ordered flags to be flown at half-staff. An ice cream shop offered free scoops and a community meeting place. Some locals changed their social media profile pictures to red ribbons with the motto “Chatham Strong.”

The driver, a 44-year-old woman from Chatham, wasn’t injured but was taken to a hospital for evaluation. Police said toxicology reports were pending. She was not in custody Tuesday. State police declined to offer further details, saying the crash remains under investigation.

“This does not appear to be a targeted attack,” state police said in a statement.

Hundreds, including students, packed Cherry Hills Church. Most wore red, the color of the Glenwood High School, where Rylee was a senior. Pastor Steve Patzia told the crowd he saw her in church weeks ago as he offered words of comfort.

“It’s good and right to feel how you feel, when you feel how you feel. I’ve had moments of grief and sadness. I’ve cried, and I’ve also had memories,” he said. “I would encourage you to share those good memories you have of her and the children that were lost as well. And I also want to say it’s OK to ask questions.”

Parents said the YNOT Outdoors after-school and summer camp programs, which employ high school and college students as counselors, are coveted and competitive to get into. In social media posts about the crash, families recalled fond summer memories at the location, which focuses on outdoor activities.

Walston’s daughters have attended the group’s summer camp and said they knew Alma and Ainsley, remembering them as energetic girls who loved to dance and made efforts to include others.

“They were sweet girls,” Walston said.
