To clear that up, Don Hancock was a goldfields kid, who joined the police and became a very effective (although couldn't lie straight in bed) detective.
Ray Mickleburg had served in the SAS in Vietnam, he and his brothers had already defrauded Alan Bond (first man to beat the Americans in over 100 years of Americas Cup yacht racing) of several hundred thousand dollars on a bogus gold nugget sale. They were then tied into a theft of gold at the Perth Mint. Ultimately convicted, later released and the two surviving brothers got about half a million each in compensation. The gold was never recovered, although some ended up at Ch7 during one of the appeals.
Tony Lewandowski and Don Hancock had cooked up bogus statements that led to the Mickleburgs being convicted. Tony committed suicide in 2004 during an inquiry or one of the appeals, at any rate, he fingered Don Hancock and himself before he topped himself.
Billy Grierson and the Jokers were out at Ora Banda (a ghost town with a pub) having a few beers around a camp site when Billy was shot dead. Allegedly by Don Hancock, in response to some fairly filthy comments made to Don's daughter. Don wasn't convicted, he was too busy drinking with the top Kalgoorlie detective for anyone to do anything like search his house, or carry out any sort of meaningful investigation.
At any rate, Snot Reid and the Jokers blew up Don's car, Don and poor old Lou the next year in revenge. Snot got a life sentence, but was paroled early for turning supergrass in an investigation.
Ultimately the Ora Banda pub burned down last year. No doubt there was arson involved, there is no chance that it was something as prosaic as a bit of dodgy wiring.
Nothing to do with Space, but Ora Banda has a bit of history.
