(MCT) — WASHINGTON — Ramzi Yousef, inmate No. 03911 at a federal “supermax” penitentiary, is serving life with no parole plus 240 years in a 7-by-11-foot cell with no bars and one small high window, far from other inmates, prison staff and the world beyond the fortress deep in the Colorado Rockies.

He has been there for 15 years, in nearly 24-hour solitary confinement at the prison they call the “Fortress in the Rockies.” Even his meals provide little relief, with the food trays shoved by unseen guards through a sally port between two steel doors. The only other inmate within shouting range has killed others in prison.
