Beni acted as a fence as well as operating other illegal activities linked to his trading post near Lodgepole Creek, Colorado, which was called by one Eastern journalist the "wickedest city on the plains." By the end of the decade the city had grown rapidly, following the addition of a stagecoach station, which was eventually named Julesburg by the townspeople in honor of Beni.
However upon Beni's appointment as manager of the station the stagecoach lines were robbed constantly. As the gang usually targeted specific stages carrying money and other valuable cargo, Beni soon was suspected of involvement and eventually replaced by gunman Jack Slade.
Slade was said to have kept the ears as souvenirs, using one of the ears as a watch fob and selling the other for drinking money.
