High Quality Content by WIKIPEDIA articles! John Harris Behan (October 23, 1844 – June 7, 1912) was from April, 1881 to November, 1882 sheriff of Cochise County, Arizona Territory. Behan was appointed the first sheriff of the newly-created county in February, 1881. The mining boomtown of Tombstone was the new county seat and Behan`s headquarters. Immediately before taking office as sheriff, Behan had served five months as undersheriff for the southern area of Pima County, which included Tombstone, succeeding Wyatt Earp in this position. Behan married and had two children, but his wife divorced him, accusing him of consorting with prostitutes. He had a relationship with Josephine Marcus for an uncertain period of time until she too was upset by his liaisons with other women, and she left him for Wyatt Earp.
