Near this site on August 8, 1903, U.S. Deputy Marshal Wiley G. Haines, Chief of Osage Indian Police Warren Bennett, and Constable Henry Majors ended the career of the notorious outlaw gang known as the Martin brothers. Wanted for murder and robbery across a five-state area, Sam and Will Martin were fatally wounded during the fierce gun battle at Wooster Mound. Marshal Haines was seriously wounded but recovered. Judge Horace Speed called it “No better stroke for law and order in the territory was ever stuck than in wiping out the vicious Martin gang.”
