Max the parrot was possibly the only witness to the murder of Jane Gill. When his owner was found suffocated in her Californian mansion, Max was passed on to an agency caring for distressed and abandoned pets. When the African Grey began to screech "Richard no, no, no" over and over again, the police thought they had a new clue. Unfortunately US law doesn't admit the verbal evidence of birds but at least Judge Errol Morris was prepared to accept a hearing.
