Was the situation around his suicide orchestrated to give him the best possible chance of killing himself? Maybe. Even that might be giving too much credit to the people who would have the motive to do so.
He was a guilty pedophile, he knew he was a guilty pedophile, and the easiest way out for him was by wrapping a prison bedsheet around his neck.
