An elderly man charged with murdering his 75-year-old wife has advanced dementia and would not know where he was if he was brought before a court, a magistrate has been told. John Huggins, 87, is accused of fatally stabbing his wife at their Guerin Avenue home in Piara Waters on Monday. Mr Huggins was due to appear in Armadale Magistrate’s Court this morning but he was instead taken to hospital after Serco staff raised concerns about his health.
