Deputies from the Snohomish County Sheriff's Office were called to assist an aid crew in the 12100 block of Highway 99 south of Everett around 12:45 a.m. Saturday.
Officers were told CPR was in progress and that there were sounds of a disturbance in the background, Lt. Kathi Lang said Sunday.
When deputies arrived, they encountered several intoxicated adults, Lang said.
A man believed to be in his 50s was taken to Swedish/Edmonds hospital where he died.
The woman was arrested and booked into the county jail for investigation of second-degree manslaughter.
The suspect and victim apparently were in a dating relationship, Lang said.
The cause and manner of death will be determined by the Snohomish County Medical Examiner's Office.
