A boy was killed in a single car wreck last Sunday in Enumclaw.

According to the King County Sheriff’s Office, the crash took place around 1:43 a.m. west of the SE 416th Street and 236th Avenue SE intersection, close to the Enumclaw Evergreen Memorial Park.

According to probable cause documents, deputies allege the Auburn woman left the road onto the shoulder and hit a ditch, causing the vehicle to launch into the air for about 150 feet, roll over, and settle about 700 feet from where it first left the road.

The boy, the woman’s son, was ejected and died at the scene despite “prolonged medical intervention by the responding deputies and medical personnel,” a KCSO spokesperson said.

Police allege no one was wearing a seatbelt in the vehicle, that a bottle of alcohol was found in the debris, and the woman smelled of alcohol. She was transported to Harborview Medical Center for treatment.

The woman had her first appearance on April 28, and charges are expected to be filed this week. The Courier-Herald typically does not name suspects until they have been officially charged.
