Illinois State Police identified Marianne Akers on Tuesday as the driver whose car crashed into an after-school camp yesterday in Chatham, leaving four people and multiple children dead. 

Officials announced that the 44-year-old from Chatham is “not in custody at this time as the cause of the crash remains under investigation.” 

The deadly incident occurred at around 3:20 p.m. when a car left the road for unknown reasons and went through a building at the YNOT After School Camp in Chatham, according to state police. The camp is about 11 miles south of Springfield. 

“The driver and sole occupant of the vehicle, Akers, was uninjured and transported to an area hospital for evaluation. Toxicology reports are pending. The cause of the crash remains under investigation, but this does not appear to be a targeted attack,” state police said Tuesday. 

“Six additional children were taken to area hospitals and one remains in critical condition,” state police said Tuesday. 

“ISP traffic crash reconstruction, patrol, crime scene services, and criminal investigations all responded to the scene along with Chatham Police Department, Chatham Fire Department, Springfield Police Department, Sangamon County Sheriff’s Office, the Sangamon County Coroner, and numerous other first responders,” it also said.
