David Radcliffe, a 58-year-old contractor and master carpenter from Alger, Washington, was killed on September 2, 2008 while working at a property on Silver Creek Drive. Radcliffe and a colleague, Greg Gillum, were shot and also assaulted with a power saw by 28-year-old Isaac Lee Zamora; the property owner found their bodies and called authorities about 5:00 p.m.

After killing Radcliffe and Gillum, Zamora stole Radcliffe’s pickup truck and went on a rampage that left six people dead and several others injured, including Skagit County Sheriff’s Deputy Anne Jackson. Zamora shot at other vehicles during a high-speed chase down Interstate 5 and later drove to the Skagit County Sheriff’s Office and surrendered. He was arrested and charged with multiple counts, including first-degree murder. Zamora said he was motivated by a belief that God told him to kill evil.

Autopsies were performed by the Snohomish County Medical Examiner’s Office and the community held memorials for the victims.
