A Melbourne man on day release from a psychiatric hospital after killing his grandparents tried to break into a series of suburban homes armed with a meat cleaver.
Ross Konidaris, 31, was ordered to be supervised for 25 years after being found not guilty by mental impairment of the 2012 murders of Triantafillio Konidaris, 81, and Stavroula Konidaris, 84.
He was to be supervised in the high security Thomas Embling Hospital, only to be released if doctors deemed him fit to return to the community.
On Friday, he was jailed for up to six years over a series of aggravated burglaries, attempted armed robbery and assault committed while on unsupervised day release.
Prison time would be a major setback in the rehabilitation Konidaris required to eventually re-enter the community, Judge Frank Gucciardo said.
But it was necessary as a deterrent and to keep the community safe, he said.
Konidaris, who has schizophrenia, had shown signs of remission and improvement in his mental health since he shot his grandparents at point blank range and set their Yarraville home on fire.
His security level was progressively lowered until February 2019, when he was moved to a low security unit and allowed daily unaccompanied access to the community.
Instead of visiting his parents in September last year, Konidaris drove to Cairnlea, pulled covering over his face and snooped through windows and a garage.
He threw an ornamental frog through a glass door and when a couple went to investigate they found him armed with a butcher's cleaver and kitchen knife.
Konidaris asked for their car keys but they fled through the smashed door and locked themselves in their garage.
Around the corner he confronted another couple, tapping the cleaver on a glass door while a man held it shut from the other side.
Konidaris fled over a fence, dumping the cleaver and picking up a pair of scissors. He approached a man a few streets away, asked for his keys and threatened him with the scissors. The man lunged, grabbing Konidaris' wrist with both hands.
Konidaris punched his face before giving up and walking away. The man suffered minor injuries. Konidaris was arrested a short time later.
Judge Gucciardo said Konidaris had told a nurse at Thomas Embling that he had used cocaine eight or 12 times on day release in the previous months because his mood had been low, he'd had a bad argument with his parents and discovered several part time jobs hadn't suited him.
He said he'd been having a "s*** day" and its use made him feel better.
Judge Gucciardo told Konidaris he could have anticipated the probable consequences of his drug use, considering the grave events that had taken him to Thomas Embling in the first place.
He ordered Konidaris serve at least four years of a six-year prison sentence. He has already served a little over a year in custody.
The earlier supervision order still applies until April 2039.
