Correctional officer stressed suicide?

You are describing PTSD. i suggest you file a workman's comp claim immediately. I am sorry that this bothers you. I have dealt with hundreds and hundreds of dead folks in my career (almost 40 years), including children who were Murdered and mutilated. I am surprised that the death of an inmate would have that serious of an effect on you. However, it is your psychology, and not mine, so I can't deny that you have a legitimate problem. Seek help ASAP, and the seriously consider another line of work. It only gets worse, not easier.
