His tombstone says he died at the hands of the "V.C." (Vigilance Committee).
"Yankee Sullivan committed suicide while confined in the committee?s headquarters, awaiting trial for various crimes. Sullivan became so panic-stricken when he heard a Vigilante say that he would probably be hanged on the morrow that he opened a vein in his wrist and bled to death before a physician could reach him."
