PHILADELPHIA (AP) — There were no dedicated corrections officers watching the housing unit at a Philadelphia prison where two inmates escaped Sunday night, and there were no armed perimeter guards when they made it through a fence surrounding the prison yard, a correctional officers union official told The Associated Press Tuesday. Authorities are still searching for two inmates — one accused of killing four people — who were gone from a Philadelphia prison for nearly 19 hours before officials knew they were missing. Prison officials say several headcounts conducted Sunday and Monday reportedly showed that all prisoners were accounted for.
