Two convicted bank robbers used a knotted rope or bed sheets to escape from the federal prison window high above downtown Chicago early Tuesday, a week after one of them made a courtroom vow of retribution, to federal judge. The escape occurred sometime between 5 a.m. and 8:45 a.m. when the inmates were discovered missing, Chicago Police Sgt. Mark Lazarro said. Hours later, what appeared to be a rope, knotted at six-foot intervals, could be seen dangling into an alley from a window of the Metropolitan Correctional Center approximately 20 stories above the ground.
