SEATTLE - Notorious serial killer Gary Ridgway has been transferred to a high-security prison in Colorado, Andrew Garber with the State Department of Corrections said.
Gary Leon Ridgway is the American serial killer known as the Green River Killer. He was initially convicted of 48 separate murders and later confessed to nearly twice that number
Ridgway, was transferred to the U.S. Penitentiary near Florence, Colorado on May 14, 2015, according to Garber.
"As part of standard correctional practice, the department constantly evaluates and reviews the overall safety and security of our operations, and makes decisions regarding the housing of offenders accordingly," Garber said Saturday.
It is unclear why Ridgway was transferred, as the Department of Corrections does not comment on offenders and their circumstances.
Ridgway, 66, pleaded guilty to killing 49 women in King County. He was spared the death penalty under a deal with King County prosecutors to cooperate in the search for bodies, and was serving a life sentence at the Washington State Penitentiary.
Supermax cells are fitted with immovable concrete furniture.
At the ADX, life is much lonelier and more monotonous. Ridgway will join other notorious prisoners such as Ted Kaczynski, the Unabomber; Atlanta Olympics bomber Eric Rudolph; Zacarias Moussaoui, who helped plan the attacks on Sept. 11, 2001; shoe bomber Richard Reid; and Ramzi Yousef, the mastermind of the 1993 bombing at the World Trade Center.
