I just read that the reason this creature has suddenly detailed what he did to Milly Dowler is that he hopes it will lead to him getting parole at some point. At the moment he has a life sentence for her along with the murders of several other young ladies with no chance of parole. There is a possibility that at some point European judges could allow for potential parole in life sentence on human rights grounds.
Apparently, "Strasbourg judges ruled in 2013 that a tariff which forces murderers to die in jail was “inhuman and degrading” following an appeal by three killers including Jeremy Bamber, who shot dead five members of his family in 1985."

I think this is nuts. I don't understand why keeping someone in prison for life is against their human rights if they have committed very serious crimes. Also, allowing Bellfield or other serial killers out would not only be potentially dangerous to the public but it would mean an end to his punishment which I disagree with. He took several lives and tortured and raped. His punishment should be that he dies in jail. That should be the least of his suffering.
