A rollover accident shut down all lanes of the northbound I-5 near State Route 516 Friday night in Kent. The accident occurred just before 11:30 p.m. when a car traveling on southbound I-5 collided with another vehicle causing the car to roll over into the median.

A woman who was a passenger in the car was ejected and thrown into the northbound lanes, according to the Washington State Patrol. Several vehicles traveling northbound hit the woman causing one of those vehicles to also rollover. That driver has only minor injuries.

Three others, including the driver who were in the first rollover vehicle and are currently being interviewed by investigators.

Troopers are investigating this as a vehicular homicide case. Alcohol is believed to be a factor in this crash.
