Steven Roy Siebert, a 60-year-old White man, was found shot to death in the kitchen of his Sudden Valley, Washington home on January 21, 2014. A son discovered the body that evening and called authorities. Investigators determined Siebert had been shot multiple times and that a 20-gauge shotgun taken from an upstairs room had been used in the killing.

Officials quickly focused on Siebert’s stepson, 42-year-old Joshua Aaron Adams, who was missing along with the family’s red Subaru Legacy and the family dog. Adams was later seen at a Highway 20 gas station in Skagit County, where he abandoned the Subaru and the dog, stole a black Ford F-150, and led police on a roughly 60-mile pursuit that ended when spike strips disabled the truck and a sergeant cut him off and arrested him. After his arrest Adams confessed to killing his stepfather but did not give a clear reason; relatives said Adams had a history of mental health problems and complained his stepfather favored other children.

Was anyone in Sudden Valley aware of tensions between Steven Siebert and Joshua Adams that might help explain what happened?
