Clayton Anthony Fountain (September 12, 1955 – July 12, 2004) was an American federal prisoner, member of the Aryan Brotherhood, and convicted murderer. Biography Clayton was born on September 12, 1955, at the U.S. Army Hospital in Fort Benning, Georgia. He was the oldest of six children, having one brother and four sisters, and was named after his father, Clayton Raleigh Fountain. The family moved every 1½ to 2 years. While his father served combat tours in Korea and Vietnam and his mother was working, Clayton, as the oldest child in family, became a surrogate for both parents when he was very young. He recalled maternal responsibilities for cooking, ironing, serving, cleaning, and caring for his young siblings. While serving in the Marines, he was convicted of murdering his staff sergeant in 1974, while stationed in the Philippines. He stole and disassembled a pistol from the ship's armory, brought it ashore, and used it to rob a Filipino guard of his shotgun. He then used the shotgun to murder his staff sergeant. No words were exchanged as Fountain shot him once in the chest, and after a brief walk he took five hostages. Fountain had been written up recently by Staff Sergeant Wrin for wearing PT gear on the mess deck in the mess hall. Fountain later had two years added to his sentence for aggravated assault and attempted escape. Fountain was sentenced to life imprisonment, and was ultimately sent to the United States Penitentiary, Marion, which was at the time the highest-security prison in the United States. Fountain murdered three prisoners and one correctional officer with a shiv while serving time at Marion, and was labeled the "Most Dangerous Prisoner" in the federal system. Fountain and another inmate, Hugh Colomb, who was serving a 25-year sentence for armed bank robbery, were convicted of voluntary manslaughter and conveying a weapon in prison and had 15 years added to their sentences. Colomb was released from prison in 2015. Columb died on June 21, 2016, at the age of 62. On October 22, 1983, Fountain stabbed Correction Officer Robert L. Hoffmann to death, hours after Fountain's friend and fellow Aryan Brotherhood member Thomas Silverstein stabbed another correction officer, Merle Clutts, to death at the same facility. The incidents resulted in a 23-year lockdown at Marion, and contributed to the creation of the federal supermax prison, United States Penitentiary, Florence ADX. Fountain was
