Curly Bill was the arch outlaw in the vicinity of Tombstone, Arizona, where Wyatt Earp and his brothers became famous due to the so-called Gunfight at the OK Corral. In a final cleanup of that violent and lawless area after the murder of Wyatt's brother, Morgan, it was reported that Wyatt killed Curly Bill in a shotgun duel. This has been disputed by many writers, but their allegations simply do not convince in view of the overwhelming evidence that Wyatt indeed did kill Curly Bill. All reported here, heavily documented.
