The family of a mentally unwell man — who has been found not guilty of stabbing his grandparents — says the beloved great-grandfather would be alive today if South Australia's mental health system had not let them down.
Austin James Smith, 23, was charged with the murder of his 81-year-old grandfather, Stanley Broadwood, and attempting to murder his grandmother, Marie Broadwood, at their McLaren Vale home, about 40 kilometres south of Adelaide, in 2020.
Police were called to the couple's house on June 9, 2020 after reports of a serious assault.
They found Mr Broadwood dead at the scene and Mrs Broadwood with serious injuries.
A statement released by police on behalf of Mr Broadwood's family at the time expressed shock and grief at his death.
"Our family are devastated by the tragedy that occurred yesterday," the statement said.
"Stan was a loving husband, father, grandfather and friend and will be dearly missed by all who knew him."
The Supreme Court today found Mr Smith not guilty by reason of mental incompetence.
The matter will return to court later this month.
Outside court, Mr Broadwood's son Chris said his family was relieved Mr Smith was now receiving the treatment and care "he so badly needed".
"If he had just received the right support prior to this tragic event, Dad would still be alive," he said.
"The truth is this could have all been avoided.
