Aurora theater shooter James Holmes has been transferred to another prison, a Colorado Department of Corrections spokeswoman confirmed.
Prison spokeswoman Adrienne Jacobson said Tuesday she did not disclose Holmes' new location or the reason behind his move, citing safety concerns. He was transferred through the interstate compact agreement, which transfers offenders between states to provide suitable confinement, treatment and rehabilitation to help lower the recidivism rate.
Asked if it's common for high-profile inmates such as Holmes to be moved, Jacobson said the interstate compact agreement "is used for lots of reasons, to include an offender's custody issue or a victim's confidentiality to preserve safety of an individual."
Jacobson could not confirm whether Holmes was moved out of state.
Holmes had been incarcerated at the San Carlos Correction Facility in Pueblo.
Prior to that, he was housed in the Colorado State Penitentiary in Cañon City.
According to The Denver Post, Holmes was assaulted Oct. 8 by Mark "Slim" Daniels as the two inmates crossed paths inside the state's highest security prison. Holmes was not injured.
Holmes, 28, is serving multiple life terms plus thousands of years in prison after he was sentenced August 27, 2015 for killing 12 people and injuring 70 others at an Aurora movie theater in July 2012. He is not eligible for parole.
