About Johnny Behan

John Harris Behan was an American law enforcement officer and politician who served as Sheriff of Cochise County in the Arizona Territory, during the gunfight at the O.K. Corral and was known for his opposition to the Earps. Behan was sheriff of Yavapai County from 1871 to 1873. He was married and had two children, but his wife divorced him, accusing him of consorting with prostitutes. He was elected to the Seventh Arizona Legislative Assembly, representing Yavapai County. In 1881, Wyatt Earp served for about five months as undersheriff of the eastern half of Pima County. When Wyatt resigned, Behan was appointed to fill his place, which included the mining boomtown Tombstone. When Cochise County was formed in February 1881, Behan was appointed as its first sheriff. Tombstone became the new county seat and the location of Behan's office. Sadie Marcus was his mistress, possibly as early as 1875 in Tip Top, Arizona, and certainly from 1880 until she found him in bed with another woman and kicked him out in mid-1881.
