A number of prisoners who are unlikely to ever be released or have received very long sentences have declared their wish to die; for example, Ian Brady. At least two such inmates have died by suicide in prison, Harold Shipman and Daniel Gonzalez, and there have been attempted suicides by such prisoners, including Ian Huntley. A number have since died in prison as a result of ill health, including Brady's accomplice Myra Hindley and the "Black Panther" serial murderer and armed robber Donald Neilson.
