Liborio, aka Laurie, was born in Reggio, Calabria, on December 15, 1927.
He was the illegitimate son of a Capo (boss) of the Melbourne Mafia style organised crime group's counter-part in Calbria.
Benvenuto's father controlled seven Italian villages.
Described as a small and dapper fellow, he migrated to Australia and went into the fruit and vegetable industry and became a well known identity in the Melbourne Market.
Liborio Benvenuto rose to prominence following the 1963-64 market murders of Vincenzo Muratore and Vincenzo Angilletta and became the undisputed Godfather of Melbourne.
Seeing that with the Market Murders full-scale civil war was likely to break out within the market community, he had worked hard as a peacemaker, at one point going to Mildura to bring about peace.
Benvenuto's right hand man was Michele Scriva who was married to a daughter of former Melbourne Godfather Domenico Italiano.
Scriva'a son, Tom, married one of Benvenuto's daughters.
Benvenuto was the father-in-law of market identity Vincenzo Muratore (killed during the wars in 1964).
His daughter was married to Vincenzo's son, Alfonso Muratore (killed in 1992), until he left her for a mistress.
Police at one stage investigated allegations that Benvenuto was involved in moving marijuana from Griffith to Melbourne.
A truck had been driven from Griffith with fruit and vegetables concealing the marijuana.
The truck would be parked in Carlton and the key left above the front tyre.
A second driver would drive the truck to a secret spot, remove the marijuana and return the vehicle.
The original driver would then take it to the market.
On May 10, 1983, Benvenuto's four wheel drive was blown up at the market.
Gelignite had been strapped beneath it.
No one was hurt. A shotgun was found in the car.
Benvenuto said at the time: "I have no enemies, only friends at the market.
"I don't know why anyone would do this at all. I have never done anyone any harm."
In 1984, the bodies of close-associates Rocco Medici and Giuseppe Furina were found in the Murrumbidgee River, believed by some to be a payback for the bomb.
One of the men had his ear sliced off, a supposed mafia warning to others that the victim had "heard too much".
Benvenuto was godfather to one of the Medici family and was a close friend of Furina.
The murders were never solved.
Police asked Benvenuto to go to its Homicide Squad offices to be interviewed about the murders.
Benvenuto walked in wearing a pork-pie hat and said: "I'm sorry I can't help but I don't know anything about it".
An astute and experienced criminal, Laurence Joseph Sumner, is rumoured to have helped plant the bomb.
Sumner was also believed to have supplied the gun which was used to kill Giuseppe "Joe" Arena, the reputed Godfather after Benvenuto's death, although it has also been said the pair were close friends.
Liborio Benvenuto died of natural causes in May 1988.
He had not considered son Frank a worthy successor and close associate Joe Arena was summonsed to Benvenuto's Beaumauris home.
Discussions were held about him becoming head of the organization.
But on his death bed Liborio Benvenuto anointed son-in-law, Alfonso Muratore as Godfather.
In a shock move however Muratore declined the offer and the next year left his wife, Liborio's daughter, Angela, for mistress Karen Mansfield.
Muratore was shot dead outside his Hampton home in 1992.
An inquest heard allegations that Frank Benvenuto took out a contract of Muratore's life for snubbing the Honoured Society and his family but was never charged.
Frank Benvenuto was shot dead in May 2000.
Joe Arena's ascension never came to pass and a rival faction murdered him outside his Bona Vista Rd, Bayswater, home on August 1, 1988, six weeks after Benvenuto had died.
Arena was shot from behind with a shotgun, the traditional Honoured Society method of death with dishonour.
The killing happened shortly after he and his wife came home from a wedding in Footscray.
Dominic "Mick" Gatto was considered a prime suspect but later spoke out and denied the allegations vehemently.
A close associate of Liborio Benvenuto's was Rosario "Ross" Gangemi.
Police allege Gangemi was involved in an extortion racket at the Melbourne wholesale fruit and vegetable market for more than 25 years.
"Rosario Gangemi is considered a senior member of the Benvenuto crime family, frequently nominated by informers as a leading contender for leadership of that crime family following the death of Benvenuto," said one intelligence document.
Gangemi served alongside Benvenuto from the 1960s to the 1980s, possibly as his deputy.
He was named by Italian police as ordering one of the market murders.
Among the international experts brought to Victoria to help investigate the killings was Italian police assistant commissioner Dr Ugo Macera.
He produced a still-secret report implicating Gangemi in the death of Angilletta.
The Macera Report, which has been seen by the Herald Sun, said: "Vincenzo Angilletta's murder is the classic example of a killing decided by the mafia."
Canberra mafia cell boss Pasquale "Il Principale" Barbaro, who became a police informer in 1989 and was murdered the following year, was secretly taped by detectives naming Gangemi as one of Melbourne's Calabrian mafia bosses.
A confidential 1991 Victoria Police report named Gangemi as one of the top 10 mafiosi in the state.
That same year, the Australian Bureau of Criminal Intelligence identified Gangemi as one of the top 30 Italian organised crime bosses in the country.
Police intelligence files show he remained a respected and influential member until his death.
On June 28, 2008, Gangemi died of natural causes, aged 86, in Coburg's John Fawkner Hospital.
His death enabled the Herald Sun to finally reveal Gangemi's high standing in the mafia.
