Final few minutes: we see remains of a human body with an "incisor" missing; the upper left incisor. Detective Constable Dan Cooper speaks of a case some years before where victim had "right incisor" recently removed.
Next scene: dog-handler Senior Constable Stephen Langley opens tin containing several teeth. MOLARS not incisors. Red herring or boo boo? (rating is based on the boo boo theory!)
