Gollehon was convicted of kidnapping and burglary while Turner was convicted of kidnapping.^[12][13]

The 1991 murders of five inmates occurred during a riot at the prison which also left eight other inmates injured.^[14] 13 other prisoners were also convicted of carrying out the riot, including death row inmate Terry Langford, who was executed in 1998 for his original crime.^[15] Robert Wild and Gary Cox were each convicted of five counts of deliberate homicide as well as burglary and kidnapping for the riot.^[16][17] Robert Close was convicted of the same crimes as Wild and Cox with the exception of kidnapping. He was however, found guilty of sexual intercourse without consent.^[18] Reed Nevins was also convicted of the same crimes as Wild and Cox, albeit four less homicide charges.^[19] Close and Nevins had prior murder convictions before participating in the riot. Close had killed Billy Joe Hall in 1974, while Nevins killed Carolyn Culbert in 1984.^[20][21] Among the other inmates involved were Kenneth Allen and Joseph Milinovich, who each pleaded guilty to one count of mitigated deliberate homicide, a lesser degree of murder in Montana. Milinovich also pleaded guilty to one count of burglary.^[22][23] The 6 other inmates who participated in the riot were Ben Cook, Harold Gleed, Daniel Lopez, Steve Ritchson, Soctt Seelye and Brian Spray. The group was convicted of various crimes in connection with the riot, ranging from homicide, burglary, rape, assault, rioting, kidnapping and criminal mischief.^[24] One of the deceased victims of the riot, Ernest Mazurkiewicz, was a murderer himself. In July 1989, he and several others robbed then killed Larry Beckwith by shooting him in Broadwater County.^[25] One of his accomplices was Joseph Milinovich, who would later become one of the many perpetrators involved in the 1991 riot that killed him and the four other inmates.^[26] In 2008, riot participant Daniel Lopez, fled Montana while on parole which then led to a nationwide manhunt. He was arrested by U.S. Marshals in Albuquerque, New Mexico two years later.^[27]
