The driver of the school vehicle, identified by police as Ronald Wickmire, 66, was killed, as was a 9-year-old boy. Two other boys, ages 12 and 6, were flown to a medical center, they said, but did not state the location. There were no other students in the vehicle, a trooper said.

The car crash that killed four people between the ages of 7 and 18 in Chatham, Illinois, "does not appear to be a targeted attack," police said.
