On May 23, 2024, Rancho Cordova was the scene of a deadly early-morning shooting that left 69-year-old Marylou S. Konvalin and her 72-year-old husband William Konvalin dead from gunshot wounds. Marylou called 911 about 1:15 a.m. to report she had been shot; deputies and Rancho Cordova officers found her unresponsive near the front door and pronounced her dead at the scene. William was located inside the home and also had sustained fatal gunshot wounds.

Authorities identified the primary suspect as the couple’s 38-year-old son, Thomas Konvalin. After the shootings he barricaded himself in the residence for about three hours. Negotiators were unable to secure his peaceful surrender. At roughly 4:15 a.m. he exited the house through a back window armed with a rifle, and two SWAT deputies fired, killing him. The Sacramento County Sheriff’s Office opened a full investigation, including an inquiry into the officer-involved shooting, and placed the deputies on administrative leave. The motive remains unclear.

Did anyone in Rancho Cordova know the Konvalin family or observe anything unusual that night?
