Crimes can't avoid DNA tests of time HE has never owned a phone and sprinkles talcum powder on the floor inside his front door whenever he goes out. According to a retired senior NSW detective, the man behind the audacious theft of $5.3 million in bullion from Kerry Packer's safe is a career criminal who has managed to stay one step ahead of the law for more than 17 years. "The guy is super cautious and was doing counter surveillance before it was invented," the retired officer said. He lives alone, always keeps to himself and has never owned a land line - let alone a mobile phone. No one has ever been arrested for Australia's largest ever bullion robbery, which had all the hallmarks of an inside job. On April 30, 1995, thieves broke into Packer's alarmed office after forcing open three doors, used an oxy torch for more than 30 minutes to cut open a 1940s safe and then carted away 25 gold bars weighing 285kg, a tiara and large Vegemite jar filled with gold nuggets. And no one heard or saw a thing. Who robbed Kerry Packer is one of the city's 10 greatest unsolved mysteries. Also on that list is the Bogle-Chandler mystery 50 years ago. The renowned scientist and a colleague's wife were found dead on the banks of the Lane Cove River. There are still no answers to the deaths of Dr Gilbert Bogle and Margaret Chandler - was it suicide, a murder-suicide or a brutal killing by a third party? Among the historic crimes still being investigated by NSW police is the campaign of terror waged against NSW Family Law Court judges in the early 80s. One was shot dead and the homes of two others were bombed - one explosion killing Pearl Watson, wife of Judge Robert Watson. Case files such as the Family Court bombings are being assessed and reviewed to determine whether any evidence can be subjected to new forensic testing. "The review has been going for much of the year and, given the voluminous case files, will continue for some time to identify new avenues of investigation," Detective Chief Inspector John Lehmann of the Unsolved Homicide Team said. We're not pursuing an active investigation at the moment but we are looking to see if there's any physical evidence that can be re-examined. The attacks on the Australian judiciary may have happened more than 30 years ago but new technologies may soon see justice finally served. They are just some of 400-plus cases still open with the State Crime Command Unsolved Homicide Team.
