When George Bear encountered his stepson, John Shaw, as the latter man was loading hay into a wagon in October 1902, they argued over money Shaw owed Bear. When Shaw failed to pay him, Bear shot him.
He then tracked down C. Edward Taylor, for whom Shaw was working, and killed him.
Because the killings occurred on the Rosebud Reservation, Bear was subject to federal jurisdiction. At trial in federal court in Sioux Falls, Bear was found guilty of murder and sentenced to death on October 29, 1902.
George Bear was hanged in Sioux Falls on December 5, 1902.
