The gunfight was the result of a personal, family, and political feud. Two months later, on the evening of December 28, 1881, Virgil Earp was ambushed and seriously wounded on the streets of Tombstone by hidden assailants shooting from the second story of an unfinished building. Although identified, the suspects provided witnesses who supplied alibis, and the men were not prosecuted. On March 18, 1882, while Morgan Earp was playing billiards at 10 p.m. at Campbell &amp; Hatch in Allen Street — in the heart of Tombstone's still-current downtown — he was killed by a shot that struck his spine, as Wyatt looked on. Once again, the assailants were named but escaped arrest due to legal technicalities. Wyatt Earp, concluding that official justice was out of reach, but with warrants obtained via the U. S. Marshal's Office, led a posse on what became known as the Earp Vendetta Ride, pursuing and killing four of the men they held responsible.
