The police believe that when they originally checked the loft,that her body was in the neighbouring loft space,that was connected by a door,and that is why it wasn't found.After loft was searched,someone has obviously moved the body back.A junior officer sparked the second search as he said the sniffer dog kept alerting toward a bedroom ceiling and he and another officer could smell decomposition.Why they didn't do a more thorough search there and then,I just don't know.Obviously over-ruled by more senior officers?
