RIDGEVILLE, S.C. — Authorities are investigating the death of an inmate killed after an attack at a South Carolina prison.

Dorchester County Coroner Paul Brouthers tells local media outlets that 62-year-old Ronald Franks died at a hospital early Monday morning.

Since 1980, Franks had been serving a life prison sentenced at Lieber Correctional Institution, a maximum-security prison in Ridgeville. Corrections Department spokesman Jeff Taillon says Franks was attacked Sunday by another inmate.

Authorities including Corrections Police Services and the State Law Enforcement Division are investigating.
