A late-night fistfight behind Don's Restaurant on 4th Street in Marysville turned deadly Tuesday, leaving one man dead at the scene and another booked into the Snohomish County Jail on suspicion of first-degree manslaughter.

What police say

Marysville police said the two men knew each other and started fighting behind the restaurant at about 10:30 p.m., according to KIRO 7. During the scuffle, one of the men went unresponsive.

Officers found him behind Don's and tried lifesaving measures, but he was pronounced dead at the scene, the outlet reports. The other man was taken into custody and booked on a first-degree manslaughter allegation.

Investigation and contacts

The arrested man was booked into the Snohomish County Jail, which is operated by the county's Corrections Bureau in Everett and handles most local bookings, according to the Snohomish County Corrections Bureau.

Investigators say it is still unclear whether the victim suffered a fatal head injury during the fight or had an unrelated medical emergency, and detectives are continuing to interview witnesses and review evidence.

Anyone with information is asked to contact the Marysville Police Department at 360-363-8300.

Legal context

Under Washington law, first-degree manslaughter applies when someone "recklessly causes the death of another person," as defined in RCW 9A.32.060, a serious felony that carries significant penalties. Prosecutors will review the case and decide how to proceed once detectives complete more of their work. The booking charge remains an allegation at this stage, not a conviction under the statute.

Local scene

Don's Restaurant, a long-standing 24-hour diner at 1216 4th Street downtown, is the location identified in police reports and local business listings. The investigation remains active, and authorities say additional details will be released as they are confirmed. Detectives are particularly interested in any video footage or eyewitness accounts and urge tipsters to reach out through the Marysville Police Department or the tip line on the city website.
