Earp moved constantly throughout his life from one boomtown to another. He left Dodge City in 1879 and moved to Tombstone with his brothers James and Virgil, where a silver boom was underway. The Earps bought an interest in the Vizina mine and some water rights. Wyatt, Virgil, and their younger brother Morgan held various law enforcement positions that put them in conflict with Tom and Frank McLaury, and Ike and Billy Clanton, who threatened to kill the Earps.
