Four people have been killed and at least 15 others injured after a North Central Texas College bus carrying the school's women's softball team collided with a semi-truck, according to CNN.
Oklahoma Highway Patrol Officer, Capt. Ronnie Hampton, said the collision happened about 9 p.m. Friday on Interstate 35, south of Turner Falls. They said they believe the semi-truck crossed the center median and struck the school van.
Officials said the bus was traveling back to NCTC in Gainesville, after a scrimmage in Oklahoma early Friday.
The National Transportation Safety Board is sending a team to investigate the cause of the accident.
