A judge ruled her 93-year-old husband was mentally competent when he stabbed his wife of 67 years to death inside their home at Findon in the city’s western suburbs, and that the attack was not the result of dementia, which he was later diagnosed with.

He was found not guilty of murder, by reason of mental incompetence.

Frank Dimasi was held in supervised care until his death.

Mrs Dimasi was well-known for her work with community meal service, Nonna’s Cucina.

Mrs Dimasi “was incredible, absolutely incredible, she just had a heart of gold”, loved ones said.
