The general practitioner of a man who murdered two women has told a review that she detected no red flags during his mental health assessment and was not informed of concerns his family had raised about his behaviour beforehand.

The doctor said she had no knowledge of those family concerns at the time she conducted the review, raising questions about the flow of information between loved ones and medical practitioners in the lead-up to the killings.

The case has prompted scrutiny of whether warning signs were missed or overlooked in the period before the fatal shootings, and whether clearer communication channels between families and GPs could have changed the outcome.
