The Florida Supreme Court upheld the first-degree murder conviction of an inmate who fatally stabbed a North Florida corrections officer, but it vacated the inmate’s death sentence based on U.S. Supreme Court decisions.

Wednesday’s rulings ordered a lower court to hold a new sentencing proceeding for Richard Franklin, who was convicted of first-degree murder in the 2012 stabbing death of Columbia Correctional Institution Sgt. Ruben Thomas.
