A 66-year-old cancer survivor who disguised himself as a woman, crept into the Sydney home of his business partner and stabbed him and his brother to death has been sentenced to at least 30 years in jail.
The woman who drove the getaway car and later gave police a false alibi to protect the man will spend the next three years behind bars.
Giuseppe Di Cianni sat motionless in the Supreme Court as he was given a sentence over the May 2009 murders that will almost certainly see him spend the rest of his life in jail.
Acting Justice Robert Shallcross Hulme described the attacks as "frenzied", with Di Cianni inflicting dozens of stab and slash wounds on each victim, leaving them lying bleeding on the floor of the house they shared in Rozelle.
"Both victims must have put up some resistance but the offender persisted with the attack," he said.
The court heard that Di Cianni's motivation for the murders was a "long-standing antipathy" towards his long-time business partner, Albert Frisoli, stemming from the belief that he had been defrauded.
Just over a week before the brothers were murdered, two court cases Di Cianni brought against Albert collapsed. Di Cianni was left with nearly $400,000 in legal debts.
Crown prosecutor Mark Hobart, SC, told the jury during the trial earlier this year that Di Cianni was "bitterly angry" about the result, which came after nearly a decade of arguments between the men and a number of apprehended violence orders.
Justice Hulme said the murders had been planned and premeditated, with Di Cianni undertaking surveillance at his victim's Goodsir Street home in the days before the murders.
The bizarre female disguise - a woman's wig and a scarf - were attempts to avoid being caught on CCTV cameras located around the home.
The court heard that Di Cianni had had little to do with Albert Frisoli's brother Mario, and had killed him because he arrived home first - around 4pm - and was "in the way".
"It is impossible to avoid the conclusion that Di Cianni had so little regard for human life that Mario was killed simply to facilitate the killing of Albert Frisoli," Justice Hulme said.
Having killed the brothers, Di Cianni walked from the home to the waiting car of deli worker Josephine Pintabona, his 54-year-old close friend and accomplice, leaving a trail of bloodied footprints behind him.
In the days following the stabbings, Di Cianni bought airline tickets, renewed his passport and caught a flight to Italy with Pintabona.
Despite the blood on the older man's shoes, Justice Hulme said he could not find beyond reasonable doubt that Pintabona had known at that point he had murdered the two brothers.
Justice Hulme significantly reduced the woman's sentence on this basis, giving her a minimum sentence of three years.
He rejected the argument that Di Cianni should be shown leniency due to his age, finding that he should not be eligible for parole until 2040, when he will be 96.
He said the offender had lead a "fairly productive life" before the murders, though one which was interrupted by treatment for bowel cancer.
Speaking outside the court, Mario Frisoli's daughter Erica said she and her family now hoped to move on with their lives.
"We've already got our life sentence," she said.
"But it is what it is, and now hopefully we can move on."
