COLUMBIA COUNTY, Fla. — Graphic details have emerged of the event leading up to the killing of a correctional officer by an inmate in March 2012, as detailed in a report obtained by Channel 4.
Investigators said an inmate stabbed 24-year-old Sgt. Ruben Thomas 14 times at the Columbia County Correctional Institution, killing him.
