In the late summer of 2000, the life of 41-year-old Simone Sampson was tragically cut short in what authorities determined to be a murder-suicide. On a Monday in late August, Sampson, a female, was discovered shot to death inside a pickup truck in the town of Clarkston, located in Asotin County, Washington. She was found in the driver's seat of the vehicle.
Investigators believe that Gary Day, 35, shot Sampson in the head with a rifle as she was driving through Clarkston.
Afterward, Day turned the weapon on himself, inflicting a fatal gunshot wound to his chin. His body was found in the passenger seat of the truck with the rifle still on his knee. The incident was investigated by the Clarkston Police Department, who quickly concluded the sequence of events.
At the time of their deaths, Sampson and Day had been living together in Nespelem, which is situated on the Colville Indian Reservation. It appeared that the two were in the process of relocating at the time of the fatal encounter. Day had recently secured a new job at a casino located east of Clarkston, near Lewiston, Idaho, prompting their move to the area. Because the case was determined to be a murder-suicide, with the perpetrator deceased at the scene, no arrests were made in connection with Simone Sampson's death.
