Question: Who was known for his association with Scott Cooley and known as an associate of the loosely federated group of outlaw Cochise County?
Context: The Little Rincon Mountains are a small range of mountains, lying to the east of the Rincon Mountains, at Tucson, of eastern Pima County, Arizona.  The range is located in northwest Cochise County and is part of the western border of the San Pedro River and Valley, the major valley and river of western Cochise County.  The river is northward flowing to meet the Gila River; its headwaters are south of the US-Mexico border in northern Sonora.  A small part of the Little Rincon range's southwest lies in Pima County. The Guadalupe Mountains of Hidalgo County (Spanish: "Sierra de Guadalupe" ) are a 13 mi (21 km) long, sub– range in southwest Hidalgo County, New Mexico, adjacent the southeast border of Arizona's Cochise County.  A small portion of the range is in Cochise County, namely the outlet of "Guadalupe Canyon", famous for the Guadalupe Canyon Massacre.  The very southern end of the range is also in the border region of Sonora, just north of Federal Highway 2. Cochise is an unincorporated community located in Cochise County, Arizona, United States.  The city was created alongside the Southern Pacific Railroad in the 1880s.  The city was primarily a stop for coal and water which were needed for trains at the time.  At its peak, the town had a population of approximately 3,000 people.  Today, only 50 people still live in Cochise.  The town is also home to several historic locations.  In 1899, Big Nose Kate, the famed sidekick of Doc Holliday, lived in Cochise while she was working at the Cochise Hotel after Holliday's death. John Harris Behan (October 24, 1844 – June 7, 1912) was sheriff of Cochise County, 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 Behan's headquarters.  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. Frank C. Stilwell (1856 – March 20, 1882) was an outlaw Cowboy who killed at least two men in Cochise County during 1877–82.  Both killings were considered to have been self-defense.  For four months he was a deputy sheriff in Tombstone, Arizona Territory for Cochise County Sheriff Johnny Behan.  Stilwell owned interests in several mines and various businesses, including a saloon, a wholesale liquor business, a stage line, and at his death livery stables in Charleston and Bisbee.  He was also a partner in a Bisbee-area saloon with ex-Texas Ranger Pete Spence. The Cochise County Cowboys were a loosely associated group of outlaw cowboys in Pima and Cochise County, Arizona Territory in the late 19th century.  The term "cowboy" had only begun to come into wider usage during the 1870s, and in the place and time, "Cowboy" was synonymous with "rustler".  Cattle thieves frequently rode across the international border into Mexico and stole cattle from Mexican ranches, which they drove back across the border and sold in the United States.  Some modern writers consider them to be one of the first and earliest forms of organized crime syndicates in American history. Scott Cooley (1845 – June 1876) was an Old West Texas Ranger and later outlaw, best known for his association with gunman Johnny Ringo. The Cochise County Sheriff's Office (CCSO), headquartered in Bisbee, Arizona, is a local law enforcement agency that serves Cochise County, Arizona.  It provides general-service law enforcement to unincorporated areas of Cochise County, serving as the equivalent of the police for unincorporated areas of the county.  It also operates the county jail system.  The Cochise County Sheriff's Office (CCSO) is sometimes referred to as the Cochise County Sheriff's Department (CCSD). John Peters Ringo (May 3, 1850 – July 13, 1882)—known as Johnny Ringo—was a known associate of the loosely federated group of outlaw Cochise County Cowboys in frontier Tombstone, Cochise County, Arizona Territory, United States.  He was affiliated with Cochise County Sheriff Johnny Behan, Ike Clanton, and Frank Stilwell during 1881–1882. Cochise County in the Old West was the site of ongoing Apache Indian attacks and a bitter feud between outlaw Cowboys and lawmen like Virgil Earp and his brothers.  The county was carved off in 1881 from the easternmost portion of Pima County during a formative period in the American Southwest.  Tensions began as soon as American settlers began arriving in what is now Cochise County.  The time period was characterized by rapidly growing boomtowns, ongoing Apache raids, smuggling and cattle rustling across the United States-Mexico border, growing ranching operations, and the expansion of new technologies in mining, railroading, and telecommunications.
