Christopher Epps, the long-tenured commissioner of the Mississippi Department of Corrections has resigned effective today.
The letter of resignation he submitted to Gov. Phil Bryant did not state a reason for the unexpected departure nor has MDOC made one public.
The Clarion-Ledger cites "multiple sources" who confirm the existence of a federal probe, but the newspaper does not specify whether Epps is the subject of the investigation.
Epps had been the longest serving prison chief in state history.
Democratic Gov. Ronnie Musgrove first appointed Epps to lead the agency in 2002; two subsequent Republican governors, Haley Barbour and Phil Bryant, kept Epps in place.
MDOC is searching for an interim commissioner.
