Mason County Sheriff’s deputies are actively searching for 24-year-old Zachary Gene Boyce, also known by the alias 'Monster,' following a violent incident in Shelton, Washington. The suspect is considered a person of interest in a shooting that occurred early Wednesday morning, November 4, 2026. Deputies responded to a report of a shooting in the 600 block of E. Walnut Street at approximately 2:15 a.m. Upon arrival, officers discovered an adult male victim suffering from a gunshot wound. The victim was transported to Mason General Hospital and subsequently transferred to St. Joseph Medical Center in Tacoma for further medical treatment. The status of the victim’s condition has not been publicly disclosed. Following the initial response, the Mason County Sheriff’s Office SWAT Team assisted in executing a search warrant at a nearby residence. Investigators believe Boyce is responsible for shooting the victim outside the residence. The shotgun allegedly used in the attack has not been recovered, and authorities warn that Boyce may still be armed and dangerous. Boyce is described as having a distinctive 'Monster' energy drink brand logo tattooed on his right cheek, just below the eye. The investigation remains active, and the Sheriff’s Office is urging the public to exercise extreme caution. Residents are asked to call 911 immediately if they see Boyce or have any information regarding his whereabouts. Authorities explicitly advise against attempting to approach or confront the suspect. Additional information is expected to be released as the investigation progresses.
