A domestic disturbance in Sandy, Oregon, on May 31, 2026, escalated into a deadly shooting and hours-long standoff that left three people dead. Jenna Mary Overson, 37, was one of the victims killed that evening along with her mother, 70-year-old Mary Beth Overson, and 16-year-old Kobyn McClure. The incident unfolded near the 39500 block of Evans Street and prompted a large police, SWAT, and medical response; neighbors were told to shelter inside while officers exchanged gunfire and a LifeFlight helicopter landed to evacuate the wounded.

Authorities say Sandy police and Clackamas County deputies responded around 4 p.m., came under fire, and returned fire during the confrontation. Sergeant Garrett Thornton was shot multiple times and airlifted to a Portland hospital. Prosecutors later charged 38-year-old Bryan Andrew Moore, identified as Jenna’s husband, with three counts of first-degree murder plus multiple charges tied to the shooting of the officer, kidnapping allegations including the couple’s 3-year-old child, hostage-related counts, and being a felon in possession of a firearm. Moore was arrested, arraigned June 1, 2026, and held without bail.

Jenna was born December 7, 1988, in West Valley City, Utah, and spent much of her childhood in Gresham, Oregon. Her obituary described her as a devoted mother of five sons who built deep friendships and loved her family.
