National Transportation Safety Board investigators said Sunday there was no evidence a truck that plowed into a bus carrying a college softball team did any braking or made any evasive maneuvers. The investigators said the truck traveled about 820 feet through a median before striking the bus carrying the North Central Texas College women's softball team late Friday as it headed back to Gainesville, Texas, following a game against Southern Nazarene University in Bethany, Oklahoma.

Investigators also said there was nothing wrong with the truck's brakes. Four of the 15 members of the team were killed and 11 injured. The accident occurred on Interstate 35 at Davis, near the Texas-Oklahoma border. Two of the injured remained hospitalized Sunday. One, Bailey Buchanan, 18, was in critical condition, WFAA, Dallas, reported. Rachel Hitt, 19, was reported in fair condition at Norman Regional Hospital.

“This is the most traumatic event that NCTC has had in its 90 years of history,” North Central Texas College President Brent Wallace said Saturday.

Oklahoma Highway Patrol Capt. Ronnie Hamptom said the driver told investigators he was reaching for a drink when the crash occurred as the truck missed a right hand curve, the Fort Worth Star-Telegram reported. The weather was described as clear and the highway dry at the time of the crash.

The driver, Russell Staley, 53, of Saginaw, Texas, was treated at a hospital and released. No charges immediately were filed.
