My recollection is that a websleuther said - upon readkng the neighbour had given a formal statement- something along the lines of "formal statement, that means she was read her rights" back in thread 1. I don't know whether that statement was correct or not and I remember thinking "must google what is a formal statement to police" but I never did. It may be that Websleuther comme t you are recalling? In all my reading on this case (like the obsessive nutter that I am ) I haven't heard the police say the neighbour was cautioned or read her rights. Sorry to
