Edmonds police are seeking the public’s help in investigating the violent assault of a Seattle man who attempted to intervene when he saw another man assaulting a woman early Sunday morning, May 31. The 37 year-old victim is now at Harborview Medical center in serious condition.

“We need the public’s assistance in identifying anyone involved in this assault.” said Detective Sgt. Michael Richardson.

The incident started just after 1 a.m. on Sunday morning. The victim was walking through the parking lot of the McDonald’s in the 21400 block of Highway 99. Investigators believe that two vehicles had pulled into the parking lot when two women got out and began to fight. A male from one of the vehicles then exited and began assaulting one of the women. The victim attempted to intervene but was turned on by all parties from the two vehicles, sustaining serious injuries to his head and body.

All of the parties involved in the assault returned to their vehicles and fled the scene prior to police arrival. Witnesses who remained at the scene reported that multiple males and females were involved, including two black males and two females of unknown race. A white or silver Volkswagen Passat was described as a possible suspect vehicle.

Investigators are continuing to work on the case and to determine if there is any video available from citizens or nearby businesses.
