hanged. 'It was disclosed that a young white official had been found hanged to death in his cell …' {The New York Times}. 'Hanged to death' is redundant. So too, for that matter, are 'starved to death' and 'strangled to death'. The writer was correct, however, in saying that the official had been found hanged and not hung. People are hanged; pictures and the like are hung.
