Gypsy,
back when I was good friends with the Deputies who transported convicted inmates to the state Penitentiaries, they would tell me what happened when they received a murderer (LEO and otherwise) or a child rapist at a particular Pen. The "white Shirts" as they were called would be ready for that individual in a nearby room. They almost never came out looking like they did before they went in.
If they were LEO & DOC murderers, there second stop was always the infirmary.
I witnessed this once with an inmate who murdered two girls in cold blood then carved them up with a hunting knife. They nearly killed him in that room.
