Clearly they must have taken hospital records into consideration. It would surely have said on medical notes if the injuries were consistant with teeth.
I have to be honest this case always struck me as a little odd. In particular i did wonder at the time if the childs mother may have been telling her what to say on the news – i can still recall how the little girl was giggling into the camera when she insisted that she personally wanted the dog put down.
I know it sounds awful but at the time i couldn’t help wondering if mummy was putting words in her mouth because something about it seemed almost ‘staged’. It was weird to watch.
