PHILADELPHIA (AP) — Authorities are 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 the inmates cut a hole in a fence surrounding a recreation yard at the Philadelphia Industrial Correctional Center on Sunday evening. But several headcounts conducted Sunday and Monday reportedly showed that all prisoners were accounted for. Philadelphia Prisons Department Commissioner Blanche Carney says “protocols were not followed.” The inmates were identified as 18-year-old Ameen Hurst, who is charged with fatally shooting four people, and 24-year-old Nasir Grant, held on conspiracy drug and weapons charges.
