On October 11, 1923, the attempted robbery of Southern Pacific Train 13 at Tunnel 13 in the Siskiyou Mountains ended with the murders of railway workers Sidney L. Bates, Charles O. Johnson, Marvin B. Seng and postal clerk Elvyn E. Dougherty. The investigation and four-year search for the suspects led to the arrests and convictions of brothers Ray, Roy, and Hugh DeAutremont in 1927. The historic case and its legacy are examined in this visual essay of records and artifacts from the Postal Inspection Service, Southern Oregon Historical Society, Smithsonian’s National Postal Museum, and other archives and museums.
