@60minutes9: Australia's most disgraced cop Roger Rogerson has died at the age of 83. The former detective, who became notorious for being the "killer cop", had suffered from a brain aneurysm in Sydney's Long Bay prison, where he was serving a life sentence for the execution murder of 20-year-old student Jamie Gao in 2014. Among other allegations levelled against him, Rogerson was charged with the attempted killing of his colleague, Michael Drury in 1984. In 2016, Drury revisited his old home, and for the first time in 32 years the retired undercover officer revealed to 60 Minutes about Rogerson's involvement in his assassination attempt.
