When a horse thief was hanged where captured, they were often placed in an unmarked grave nearby, but when the thief was hanged in town they were normally buried in the local cemetery. Many times they were unmarked, with no one willing to order and pay for a permanent marker, and sometimes they had a temporary marker.
This particular horse thief was marked much later. While his name was unknown, his deed is remembered forever.
