Slowly all of the Earp assets in Tombstone were sold to pay for taxes, and the stake the family had amassed eroded. Wyatt and Warren joined Virgil in San Francisco in late 1882. While there, Wyatt rekindled a romance with Josie Marcus, Behan's one-time fiancée. His common-law wife, Mattie waited for him in Colton but eventually realized Wyatt was not coming back (Wyatt had left Mattie the house when he left Tombstone). Earp left San Francisco with Josie in 1883 and she became his companion for the next forty-six years (no marriage certificate has been found). Earp and Marcus returned to Gunnison where they settled down, where that state’s governor refused to extradite Wyatt back to Arizona on the grounds that he could not get a fair trial, and Earp continued to run a faro bank.
