Arthur Edward Dunn, a 43-year-old California Highway Patrol officer, was killed on July 9, 1977 while transporting a drunk-driving arrestee. Around midnight on State Highway 89 near the Dana cut-off in Shasta County, the suspect had a small-caliber handgun concealed and shot Officer Dunn from behind. After being shot, Dunn’s patrol car went over an embankment. When he did not arrive at the jail or answer radio contact, a search found the patrol car and the fatal shooting.

The suspect escaped briefly by kicking out the patrol car’s rear window but was captured nearby and later charged with second-degree murder. He was convicted on April 26, 1978, and received a nine-year sentence, the maximum for second-degree murder at the time. Officer Dunn had served 14 years with the CHP and spent a decade at the Burney Resident Post.

A section of State Route 89 in Shasta County was dedicated in his memory on November 4, 2002.
