A domestic violence call on the evening of May 31, 2026, in Sandy, Oregon, escalated into a tragic event that left three people dead, including 70-year-old Mary Beth Overson. The incident, which unfolded at an apartment complex in the 39500 block of Evans Street, also claimed the lives of her 37-year-old daughter, Jenna Mary Overson, and a 16-year-old neighbor, Kobyn McClure. The suspected shooter was identified as 38-year-old Bryan Andrew Moore, Jenna's husband and Mary Beth's son-in-law. The situation quickly evolved from a domestic dispute into an active shooter event and a prolonged standoff with law enforcement.
Responding to reports of gunfire, Sandy Police officers were met with hostility from Moore, who had barricaded himself inside the apartment. During the confrontation, Moore is alleged to have fired multiple shots, seriously injuring Sandy Police Sergeant Garrett Thornton. The standoff prompted a shelter-in-place order for the surrounding neighborhood as law enforcement, including the East County Metro SWAT team, converged on the scene. According to court documents, Moore used people as human shields during the hours-long ordeal. The standoff concluded just before 8 p.m. when Moore surrendered to police without further incident and was taken into custody.
Following his arrest, Bryan Andrew Moore was charged with three counts of first-degree murder for the deaths of his wife, mother-in-law, and the teenage neighbor. He also faces charges of attempted aggravated murder, felon in possession of a firearm, and two counts of first-degree kidnapping. An indictment later expanded the charges to a total of 17 counts, including six counts of attempted aggravated murder, first-degree assault with a firearm, and unlawful possession of methamphetamine. Moore pleaded not guilty to all charges during a court appearance and is being held without bail at the Clackamas County Jail. The investigation into the triple homicide is being handled by the Clackamas Interagency Major Crimes Team, as it involved an officer-involved shooting. This case, originating from a domestic dispute, highlights a devastating instance of gun violence that resulted in the loss of three lives and the serious injury of a police officer, leaving a family and a community to grapple with the aftermath of the tragedy.
