An elderly man charged with violently killing a fellow resident at a Christchurch rest home's dementia unit has died

The man, in his 70s, was charged with manslaughter of a man in his 80s, at Heritage Lifecare last year

The case was going through the High Court in Christchurch when the accused died earlier this year after suffering severe dementia.

Heavy suppression orders have blanketed the case, preventing naming the resident who died, his alleged attacker, and the name of the rest home.

The court confirmed final suppression orders for both men today - but has allowed identification of the rest home
