The crash happened just north of Dunn Road.

The school bus driver, Verl Keith, 70 of Spencer suffered hand and head injuries and was transported to IU Health Bloomington Hospital for treatment.
Trooper William Brown and emergency personnel at the scene praised Bus Driver Verl Keith for his diligence and persistence as he fought to keep his heavily damaged bus upright and away from the approaching trees.
Trooper Brown said “The school bus left the roadway completely and could have easily turned over. If that would have happened, this crash would have seen a lot more kids severely injured.”
Trooper William Brown investigated the crash. Assisting agencies at the scene included the Owen Valley Fire Department, Owen County EMS Ambulance Service, Owen County Sheriff’s Department, Spencer Police Department, Bland’s Towing and Craney Towing Service’s.
