Prison Escapes Pennsylvania

Six inmates who tunneled out of a maximum-security prison used a jackhammer and other prison-issue power tools, along with blueprints of the place, guards said. The men--two of them convicted killers--apparently used tools assigned for use by inmates working on a steam-pipe installation project, according to the guards, who spoke on condition of anonymity. Some prisoners worked unsupervised on the pipe-installation project for as much as an hour at a time, one guard said.
