Philadelphia police search for two escaped inmates, one charged with four murders.

Two prisoners, including a man accused of being involved in four homicides, escaped from a Philadelphia correctional facility on Sunday night. The escapees were identified as 18-year-old Ameen Hurst and 24-year-old Nasir Grant. Hurst was in custody for four homicides, while Grant was in custody for narcotics violations, theft, and firearm charges. The authorities are working with U.S. Marshals to bring the two back into custody, and an investigation is underway to determine why the two weren't listed as missing during headcounts. Anyone with information on their whereabouts is asked to call Northeast Detectives or 911.
