Colorado Theater Shooter No Longer in Colorado James Holmes moved out of the state after a fight By Luke Roney, Newser Staff Posted Mar 4, 2016 12:10 AM CST 26 comments Comments James Holmes appears in court for the sentencing phase in his trial at Arapahoe County District Court in Centennial, Colo. (RJ Sangosti/The Denver Post via AP, Pool, File) (Newser) – Colorado theater shooter James Holmes has been moved to a prison outside of the state, the Denver Post reports. A spokeswoman cited safety concerns as the reason for the move but declined to say where Holmes is currently incarcerated as he serves his life sentence. "He is not in the state" is the only official line. That safety concern likely stems from an October attack on Holmes by a fellow inmate at the Colorado State Penitentiary in Canon City. According to ABC News, a security gate was mistakenly left open as Holmes exited the office of his case worker, giving inmate Mark "Slim" Daniels the opportunity to attack the man who killed 12 people and injured dozens more when he opened fire in a movie theater in 2012. Daniels “ran through the slider, squeezing through as it was closing toward offender Holmes," says a prison report cited by ABC. "Offender Daniels began hitting offender Holmes, in and around his head, with his fist.” Daniels, who is serving time for auto theft and other crimes, continued the attack even as guards tried to restrain him. Daniels wrote of the attack in a December letter to alt-weekly Westword: "I'm so sorry I couldn't wipe him out and sent [sic] him packing to Satan's lake of fire. It was just impossible to do by myself with so many cops. I did get him six or seven good ones." Allowing Holmes to come into contact with other prisoners "was not part of the management plan of him," says Colorado prisons chief Steve Hager. Daniels received 60 days in segregation, lost privileges, and also was transferred.
