Milton William Cooper (831)

11/5/2001: Cooper, a writer and significant figure in sovereign citizen and fringe conspiracy circles, had been openly defying county and federal officials. The U.S. Marshal Service had named him a major fugitive in 2000. Deputies serving a warrant for assault on a trespasser were met with a firefight; Cooper shot one of them twice in the head. Cooper was hit by return fire and died the next day. The deputy survived.
