I've always heard that paedophiles are housed together in the same wing, separate from the prisoners who are not child abusers.
So as far as I'm aware, child abusers are not by themselves, in solitary confinement, but housed with fellow child abusers.
That's why I think it's a very good possibility that the murderer is a child abuser themselves.
Because why would someone who'd done the same crime slit Watkins' throat?
They could have a reason for it that's unrelated to his offences. Watkins was apparently attacked two years ago in prison and it was due to a drug debt and something to do with the ladies who were visiting him - nothing to do with him being a paedophile.
It's possible that this could be a similar scenario. His killer could be a paedophile and so their motive may not be outrage at Watkins' crimes.
