A third suspect has been arrested in connection with a Labor Day weekend shootout between rival motorcycle clubs outside a restaurant in Birch Bay. Court records filed September 9, 2026 in Whatcom County Superior Court identify 39-year-old Jereme Paul Robertson as the alleged president of the Mongols Motorcycle Club. Robertson was booked into the Whatcom County Jail at approximately 3:40 p.m. on Friday, September 11, and was being held without bail as of that evening.
What the Court Records Say
According to the affidavit of probable cause filed by the Whatcom County Sheriff's Office, Robertson arrived at the scene at approximately 7:20 p.m. on September 6 riding a black motorcycle with high "ape hanger" handlebars, a white or clear headlight, and a black motor. The bike matched photographs on Robertson's personal Facebook profile, a detail that investigators used to connect the physical description of the motorcycle on surveillance footage to Robertson's identity. He arrived alongside fellow Mongols-patched riders Roman Mayne De Isla Puga and Diego Uribe-Gonzalez, the two men previously charged in connection with the shooting.
Surveillance footage reviewed by investigators showed Robertson leading the trio across the street to confront William Husky, a man wearing Bandido patches who was walking into the restaurant with his wife. The three men surrounded Husky in an alcove and ordered him to remove his Bandido vest. Stripping a rival club member of their patch vest is considered one of the most serious acts of disrespect in outlaw motorcycle club culture, and demanding it in a public setting signals an intent to dominate or humiliate a rival in front of witnesses.
When Husky stated he would defend himself and drew a pistol, the three Mongols-patched individuals attempted to forcibly take the weapon. During the physical struggle, Husky's firearm discharged into Uribe-Gonzalez's right shin. As Husky backed away with his weapon pointed, Mayne De Isla Puga ran across the street to retrieve a firearm from his motorcycle. Robertson, meanwhile, retreated toward the south end of the Bay Breeze building before returning with what investigators believe was a silver revolver. Surveillance video shows Robertson firing an estimated six rounds toward the north, at Husky and his wife, from roughly 20 feet away. The shooting occurred as civilian traffic, families, and children passed on the surrounding sidewalk and street, creating significant risk of injury to people who had nothing to do with the dispute. Robertson fled before deputies arrived. Investigators made contact with his significant other, who had arrived at the scene after Robertson called her.
The Charges Robertson Faces
Whatcom County prosecutors have charged Robertson with three felony counts. The first is Attempted Robbery in the First Degree under RCW 9A.56.200, for confronting Husky, demanding the surrender of his Bandido vest, and attempting to forcibly seize Husky's firearm. Robbery in the first degree involves force or threats combined with a deadly weapon or serious physical injury, and the allegation that Robertson and his companions attempted to take both the vest and the gun by force satisfies the elements of that charge.
The second count is Assault in the First Degree under RCW 9A.36.011, for leveling and discharging approximately six rounds from a handgun at Husky from about 20 feet. Assault in the first degree is one of Washington's most serious violent felonies and carries substantial mandatory minimum sentencing under the state's Sentencing Reform Act. The third count is Reckless Endangerment under RCW 9A.36.050, for discharging a firearm into a populated public area and placing uninvolved civilians, motorists, and bystanders at immediate risk of death or serious physical injury. The reckless endangerment count reflects the reality that Robertson allegedly fired into a public space where innocent people were present, compounding the danger beyond what the assault charge alone captures.
A bench warrant for Robertson's arrest was issued September 9. Bail had not been set as of the time of booking, with bail determinations expected at an initial arraignment hearing. The decision to hold Robertson without bail pending arraignment suggests prosecutors presented the court with arguments for dangerousness or flight risk sufficient to justify detention.
Context: The Labor Day Weekend Shooting
The September 6 confrontation outside the Bay Breeze building in Birch Bay was the incident that generated all three sets of arrests and charges over the following days. The Whatcom County Sheriff's Office investigated the original shooting, which resulted in the initial arrest of Mayne De Isla Puga and Uribe-Gonzalez within days of the incident. Robertson's arrest completes what prosecutors have presented as a three-person Mongols crew responsible for initiating the confrontation. The investigation moved relatively quickly, aided significantly by the availability of surveillance video and Robertson's identifiable motorcycle.
The Mongols Motorcycle Club is a 1-percenter motorcycle organization with chapters across the United States that has been the subject of federal and state law enforcement operations over several decades. The Bandidos, whose member Husky was wearing patches when the confrontation began, are a rival 1-percenter organization. Confrontations between the two clubs have occurred in multiple states, and law enforcement agencies with jurisdiction over areas where both clubs operate monitor their interactions closely. Birch Bay is a small beachside community in western Whatcom County, southwest of Blaine and north of Ferndale, where incidents of this kind are uncommon. The Labor Day weekend timing meant the area had elevated visitor traffic, which contributed to the number of civilians present when the shooting occurred.
The charges filed against all three defendants remain allegations at this stage. Robertson, like Mayne De Isla Puga and Uribe-Gonzalez, is presumed innocent until proven guilty in court. Arraignment and bail hearings will be scheduled in Whatcom County Superior Court. For earlier coverage of the first two arrests in this case, details on the initial charges are available here.
