Federal Prohibition Agent Charles A. Wood, U.S. Department of the Treasury, Bureau of Internal Revenue, Border Department, was killed on March 21, 1921, along with his partner, Agent Stafford E. Beckett, while attempting to execute a search warrant on whiskey smugglers at the Shearman Ranch in El Paso, Texas, near the U.S. – Mexico border.
