I find it hard to believe that all of the guards meant to be watching over a high-profile prisoner on suicide watch just happened to disappear at the same time the multiple cameras also meant to be watching over him failed, and those both happened to coincide with the period he's said to have killed himself.
Either it's unimaginably high levels of incompetence and neglect, or somebody paid off a bunch of people. Considering it was rich pedos who wanted him dead, I don't find the latter unreasonable to believe
