I was working as an EMT in Southern New Mexico in the early 80's. Had a call for an assault. Turned out to be a woman who looked about 18, but was much older, having lived and cared for herself well. She was unconscious from having been stabbed in the head with a screwdriver, and died shortly after arrival at the ER. Several years later I worked as an LPN for the NM Department of Corrections while pursuing my RN education. One of the inmates was the convicted murderer of the woman I mentioned earlier. He was on a fair amount of anti psychotic medication. I never had a conversation with him, never even saw him talk. He came to the med line, took his meds, and went his way. Always had the "thousand yard stare." One day I arrived at work and the prison was on lock down. The same guy had killed a corrections officer. Beat him to death with a piece of wood, in full view of inmates and security. They were in the lieutenants office which had bullet proof glass looking into the compound. The inmate had barricaded the door from the inside, and there was no way to get in until he chose to come out. The guard he beat to death was in his early thirties, married with a 3 year old and newborn child. The inmate was turned over to the feds for his own protection, routine since he wouldn't be safe in NM. Some months later I read about him killing another guard at a prison in Florida. Heard no more of him, but so wish that justice was finally done for him.
