OKLAHOMA (CNN)- Four people died after a tractor-trailer crashed into a bus carrying members of a college women’s softball team late Friday in southern Oklahoma, a law enforcement spokesman said.
The bus, which belonged to North Central Texas College, was transporting its softball team back from a game, the school said. It was carrying 15 female students and one male coach.
“The semi departed the roadway to the left and traveled into the median and crossed the median, entering the southbound lane where it impacted the bus,” said Oklahoma Highway Patrol Cpt. Ronnie Hampton.
The National Transportation and Safety Board were sending a team to investigate the accident, which occurred on Interstate 35 in the Arbuckle Mountains near Davis, about an hour south of Oklahoma City.
Eleven students were taken to the hospital, as well as the driver of the tractor-trailer, Hampton said. Two of the injured were flown by air ambulance to the Oklahoma University Medical Center in Oklahoma City.
Earlier, the highway patrol had reported that two semis were involved in the accident but later revised that to one truck.
