Two medical helicopters were requested to the scene due to the severity of the injuries. One of them was canceled because of a prolonged estimated arrival time, Vucha said.

An additional ambulance from the Hebron-Alden-Greenwood Fire Protection District was requested to assist with patient care and transportation.
