Otero is believed to have written a letter that described a portion of the Earp Vendetta Ride in 1882, when his father met the Earp posse in Albuquerque. Otero's presence in Albuquerque was corroborated by local newspapers. According to the letter, Wyatt and Holliday were eating at The Retreat Restaurant in Albuquerque, owned by "Fat Charlie", "when Holliday said something about Earp becoming 'a damn Jew-boy.' Earp became angry and left…. [Henry] Jaffa told me later that Earp’s woman was a Jewess. Earp did mezuzah when entering the house." Wyatt was staying with a prominent businessman Henry N. Jaffa, who was also president of New Albuquerque’s Board of Trade. Jaffa was also Jewish, and based on the letter, Earp had while staying in Jaffa's home honored Jewish tradition by performing the mezuzah upon entering his home.
