BRENT, Ala. – The Alabama Department of Corrections is investigating a fatal stabbing that happened Monday at the Bibb Correctional Facility in Brent.

34-year-old Jamie Marcus Witherspoon was fatally stabbed during an altercation with another inmate inside the facility around 11 a.m.

Witherspoon was taken to a local hospital where he was pronounced dead.
