This tormented man's murder victim was his father, sadly - my condolences to the whole family for the ordeal you've been through over the years. May you all find some peace.
I see that he was charged with arson numerous times; I understand that's an unusually common method of killing oneself in prison. He was also apparently assaultive towards staff, though the disciplinary record doesn't ever tell the whole story. It's possible he had some very good reasoning for this, too, but very seldom does a man who is not being influenced by delusions and hallucinations tattoo an inverted 5-point star on his forehead. I think this man was likely seriously mentally ill, and he was being held in solitary confinement because he was considered to be so dangerous. That's where most suicides take place.
In any case, there have been a rash of suicides under the watch of Corizon's mental health staff. So, if anyone knows anything about exactly how Raymundo died or what may have preceeded it, please get in touch with me at email@example.com or 480-580-6807.
