Ivan Milat died over the weekend at Long Bay Prison after succumbing to cancer, aged 74.
Australia's most notorious serial killer refused to give police any more information about unsolved murders or missing person reports that have been linked to him.
Despite being convicted of the brutal murders of seven backpackers, including two British nannies, three Germans and two Australians, he maintained his innocence until his dying breath.

While the rest of the country was against him, it seems like the majority of Milat's family supported him.
Milat's nephew Alistair Shipsey told Sunrise this morning: "Nobody has produced one thread of evidence yet that he's murdered one single person.
"We talked about discrepancies and how the judge said they had no proof Ivan Milat murdered anybody."

One of his nine brothers, Bill Milat, told The Daily Telegraph that Milat couldn't have done the crimes that prosecutors got him convicted of.
"He was an all-round nice bloke," he said. "We don't believe for one second that he did it."
His brother Richard told Channel 9: "I thought he was a great fella, because he was always a great fella to me.I never thought I was the brother of a serial killer...I think he was the best brother, I lived with him for 20 years."
Mr Shipsey added to 10 News First: "He wasn't in a good way at all, I think because of the morphine they were giving him, but he never shut up about the case, he talked the whole time.

"I'm glad it's over. I'm glad he's free and he doesn't have to look at those four walls anymore. He's innocent."
Channel 10 has also revealed that Milat's family was given a sealed, one-page letter from the serial killer just two days before his death.
The network claims police are aware of the note but don't believe it contains any information relating to a confession or about potential other victims.

Investigators visited Milat several times after learning of his cancer diagnosis, hoping to get anything out of him. Sadly for them, he remained tight lipped until he took his last breath.
Milat was caught after targeting British backpacker Paul Onions, who managed to escape from the killer and notify the police.
He buried the bodies in shallow graves in Belanglo State Forest, which is situated 75 miles south-west of Sydney. The murders took place between 1989 and 1992.
