Karl Williams

The clinic had just finished, and many adults and children were standing around. Moran and Barbaro sat in the front seats of Moran's minivan—with the five young children sitting in the rear—a gunman approached and fired both a shotgun and a handgun into the vehicle. Both men died at the scene. Three years earlier, a shotgun and a handgun had been used to gun down Moran's half-brother Mark. Two of the children in the minivan were Moran's, and all were age 7 or under.

The gunman—nicknamed "The Runner" before he was identified—later told police that Carl Williams was the person who paid him to kill Moran and Barbaro, and that Williams had paid him less than the fee he was originally promised. Williams later pleaded guilty to the murder of Jason Moran.

The circumstances of his death were investigated by the Victorian Ombudsman. A report critical of Corrections Victoria (for approving Williams to share a cell with Johnson) was released in April 2012. Two months later in June 2012, the Department of Justice Secretary Penny Armytage resigned and earlier in May the Corrections Victoria Commissioner Bob Hastings had resigned.

He was sentenced to life imprisonment with a non-parole period of 35 years for ordering the murders of three people and conspiracy to murder a fourth (which was unsuccessful). On 19 April 2010, while incarcerated at HM Prison Barwon, Williams was beaten to death with the stem of an exercise bike by another inmate, Matthew Charles Johnson.

On 19 April 2010 News Limited newspapers including the Herald Sun revealed that Victoria Police were paying $8,000 in school fees for Williams' daughter. The reason for the payment was not revealed at the time. However, during the 2011 murder trial, it was revealed Williams had turned informant and had struck a deal with Assistant Commissioner Simon Overland. Williams gave information on several unsolved murder cases believed to have involved corrupt officers and it was also revealed his murderer may have been implicated in at least one of those cases. Williams' lawyer Rob Stary said Williams was upset about the publication of the story.

On 19 April 2010, Williams died from head injury while incarcerated at Barwon Prison. He was struck with part of an exercise bike by another inmate, Matthew Charles Johnson, who was convicted of the murder, and sentenced in December 2011 to 32 years in jail.

Williams' funeral was held on 30 April 2010 at St Therese's Catholic Church in Essendon. He was buried in a golden coffin. In January 2011 it was reported that Williams' resting place consisted of a nameless plot, without a headstone.

Williams was portrayed by Gyton Grantley in the 2008 Australian television series Underbelly, based on the events surrounding the Melbourne gangland wars from 1995 up to his arrest in 2004. In 2014 Grantley reprised the role in Fat Tony & Co..

On 28 February 2007, Williams pleaded guilty in the Supreme Court of Victoria to the murders of Lewis Moran, his son Jason Moran, and Mark Mallia (whose name was initially suppressed by the court).

Williams, who described himself as a semi-professional gambler, was banned from the Crown Casino on 2 April 2004 by police commissioner Christine Nixon under the Casino Control Act. Williams' mother Barbara was found dead in her Melbourne home on 22 November 2008. She had been suffering from depression.

Lewis Moran was fatally shot in the inner-city Brunswick Club on 31 March 2004. Williams pleaded guilty to his murder.

On the Saturday morning of 21 June 2003, Jason Moran and a colleague, Pasquale Barbaro, were fatally shot in the parking lot of the Cross Keys Hotel in Strathmore, Melbourne, where Moran and Barbaro had brought five children to attend an Auskick football clinic.

Mark Mallia was an associate of murdered underworld criminal, Nik Radev. At 8.05am on 18 August 2003 a fire was reported in a stormwater drain in Sunshine. Fire brigade members attending to the fire recovered a wheelie bin containing the remains of a charred body inside, later identified as Mallia.

Marshall was shot outside his luxury South Yarra home in front of his five-year-old son on 25 October 2003.

It was also revealed that Williams was serving a sentence of 21 years for the 2003 murder of Michael Marshall. The outcome of this trial had previously been suppressed.

Mark Moran was shot on 15 June 2000 after arriving at his home in Aberfeldie. Williams was due to stand trial for his murder, but the charge was dropped when he pleaded guilty to other murders.

On 25 November 1999, Williams, along with his father, George and another associate, were arrested and charged with drug trafficking after a raid on a Fir Close Unit in Broadmeadows illegal drug factory. In excess of 25,000 amphetamine tablets were seized by police, estimated to be worth up to A$ 20 million.

On 13 October 1999, Williams was shot in the abdomen by Jason Moran because he owed the Moran family $80,000. This event sparked a lengthy underworld war known popularly as the Melbourne gangland killings. In 2002, after meeting through a mutual friend Tony Mokbel, Williams courted the services of the murderer Andrew Veniamin as his right-hand man until late 2003.

Carl Anthony Williams (13 October 1970 – 19 April 2010) was an Australian convicted murderer and drug trafficker from Melbourne, Victoria. He was the central figure in the Melbourne gangland killings as well as its final victim.

Williams attended Broadmeadows Technical School, leaving in Year 11. Williams spent much of his childhood in Western Melbourne with his friends and older brother Shane who died of a heroin overdose in 1997. He was married to convicted drug trafficker Roberta Mercieca (born 23 March 1969), with whom he had one daughter, Dhakota, born 10 March 2001. Williams held various labouring jobs before opening a children's clothing store in partnership with his wife, which eventually failed.
