The State Highway Patrol still has not been able to interview the driver of a school bus involved in a double-fatality accident last month, but it has decided the driver’s in attention is what caused the crash. Troopers say they don’t know why the driver was inattentive. The bus rammed a parked asphalt truck near Bowling Green. A student on the bus and the driver of the truck were killed. The driver remains in serious condition at a St. Louis hospital.
