Brilliant reconstruction of the crimes of Perth’s hare-lipped serial killer…this six-year reinvestigation leaves no room to doubt that Darryl Beamish did 15 years for a murder committed by Cooke in 1959 and that John Button did five years for a 1963 murder by Cooke. Why do the guilty get off while innocent people such as Beamish, Button and Lindy Chamberlain go to prison?
