Mentally ill killer 'fell through cracks' A mentally ill man who stabbed his father and sister to death had "fallen through the cracks" of the mental health system, a Sydney inquest has heard. A Sydney inquest has heard health professionals never detained Anthony under the Mental Health Act despite years of "bizarre and often threatening" behaviour. Giving evidence on Tuesday, Peter McGeorge, a psychiatrist at Sydney's St Vincent's Hospital who treated Anthony from November 2006 to February 2007, said the decision not to schedule Anthony was made in consultation with other psychiatrists. Dr McGeorge conceded that opinions were split on the issue, but ultimately it was decided to continue a "therapeutic relationship" with Anthony and encourage him to take anti-psychotic drugs, rather then have him committed. He said Anthony's symptoms and personality suggested he needed to be "engaged wherever possible on a voluntary basis." Dr McGeorge rejected a statement made by another psychiatrist in a report, extracts of which were read at the inquest, that it "beggars belief" that Anthony was never committed. "He wasn't there at the time," Dr McGeorge said. At the time Dr McGeorge was treating Anthony there was no direct evidence of hallucinations, delusions or a serious mood disorder. Anthony was involved in therapy and wasn't expressing homicidal thoughts, the inquest was told. Anthony was a "particularly complex case" and "reasonable minds" could differ on how to treat mentally ill patients at critical moments. The inquest has previously been told Anthony had for years suffered delusions and believed neighbours were "tormenting him," and that his family was part of a conspiracy targeting him. Dr McGeorge agreed with a suggestion from counsel assisting the coroner, Peggy Dwyer, that Anthony "fell through the cracks" in the mental health system after he left his care. "He was not seen on a consistent basis, that's true," Dr McGeorge said.
