Boston Celtics star Isaiah Thomas’ sister died in a car crash early Saturday.
Chyna Thomas, 22, was killed on I-5 in Washington state around 5 a.m. when her car veered off the road, according to KIRO7. She died at the scene of the accident.
A witness told the police that Chyna Thomas was driving her 1998 Toyota Camry “normally” but all of a sudden the vehicle began moving “very casually” onto the shoulder of the main highway.
Chyna Thomas’ car drifted nearly 50 feet before hitting a barrier on the side of the roadway and landing on a metal poll.
Authorities believe she may have fallen asleep at the wheel, according to Q13FOX.
“That vaulted the vehicle head-on into the sign post,” State Patrol spokesman Trooper Nick King said.
According to the state patrol, Chyna Thomas was not wearing a seat belt.
Isaiah Thomas, who played college basketball at the University of Washington, is expected to play in the Boston Celtics’ postseason opener against the Chicago Bulls on Sunday.
He was notified of his sisters’ death following the Celtics’ afternoon practice, according to ESPN. Celtics teammate Avery Bradley, who is also from Washington state, pulled Isaiah Thomas away from an interview with a reporter and into a trainer’s room to tell him.
“We are terribly saddened by the tragic loss of Chyna Thomas,” the Celtics said. “The thoughts & prayers of the entire organization are with Isaiah & his family.”
NBA Commissioner Adam Silver also released a statement on her death.
“The NBA family mourns the tragic passing of Chyna Thomas and we send our deepest condolences to Isaiah, his family and the Celtics organization during this difficult time,” he said.
People from around the NBA took to Twitter to send their regards to Isaiah Thomas and his family.
