I think it is actually Richard Hillman. They pulled A body out of the water! Didnt say who's body, no-one actually saw the dead body....could be anyone's body. I think they pulled a body out of the water, presumed it was Richards, but he climbed out afterwards and is living a fantastic life somewhere under a different name so that they can't catch him for all the murders that he did.
Honest i haven't given this a lot of thought!!
