The drama began just before 4 a.m. when Kent police asked for assistance in stopping the suspected drunk driver, who officers were pursuing south down I-5 after he failed to pull over, said Sgt. Cindi West of the King County Sheriff's Office.
Sheriff's deputies joined in the pursuit and chased the suspect south on Martin Luther King Way. During the pursuit the suspect rammed a deputy's patrol car and then continued fleeing on Martin Luther King Way.
The suspect lost control at a turn in the road where Martin Luther King becomes Sunset Road. The man's vehicle went over a barrier and slammed into a tree.
The man was pronounced dead at the scene. He has not yet been identified, West said.
The deputy whose was car was hit was taken to Harborview with minor injuries. The deputy has since been released from the hospital and is in good condition.
The incident remains under investigation by the Sheriff's Office Major Accident Response and Reconstruction Unit, West said.
