Chyna Thomas, the 22-year-old sister of Boston Celtics star Isaiah Thomas, was killed Saturday morning in a single-car crash on Interstate 5 in Washington.
According to the Washington State Patrol, Chyna Thomas was pronounced dead at the scene of the accident, which occurred on the shoulder of I-5.
The accident took place around 5 a.m. PT. The Washington State Patrol reported the vehicle initially was driving normally southbound but eventually tailed off.
“All of a sudden, it started to drift very casually onto the left shoulder,” State Patrol spokesman Trooper Nick King said.
The car traveled approximately 50 feet before crashing headfirst into a sign post. The Washington State Patrol reported Chyna Thomas was not wearing her seat belt.
The Celtics released a brief statement in response to the news.
We are terribly saddened by the tragic loss of Chyna Thomas. The thoughts & prayers of the entire organization are with Isaiah & his family.
