Holmes had been at the Colorado State Penitentiary in Canon City before he was moved to Pueblo, and was often in solitary confinement.
Authorities have only said Holmes was moved to either a federal prison or another state prison out of state.
Brauchler had pushed for the death penalty in Holmes’ case, but the jury couldn’t unanimously decide that Holmes should be sentenced to death.
Colorado Gov. John Hickenlooper has said he won’t sign off on any executions while he’s in office, and Brauchler has made it a point over the past year that he would like to bring the death penalty back to Colorado if he’s elected governor.
