The Washington State Patrol is trying to find witnesses to a fatal rollover crash late Friday on Interstate 5 in Kent.
The car was traveling south on I-5 just south of state Route 516 when it hit the left guardrail, flipped and landed upside-down in the median, Trooper Rick Johnson wrote in a news release.
A female passenger was ejected from the car and landed in a northbound freeway lane, where she was struck multiple times and killed.
King County medical examiners Tuesday identified the woman as Joy Brannon, 28.
Never miss a local story.
Troopers are unsure which of the other three people in the car was driving at the time of the crash, Johnson wrote, though all were thought to be impaired.
Because of the suspected impairment, the crash is being investigated as a vehicular homicide.
A northbound car rolled off the right side of the freeway as the driver tried to avoid the woman’s body. The driver was injured.
Anyone with information about the crash is asked to contact Detective Vik Mauro at 425-401-7746 or email@example.com.
