William MacDonald’s victim #4 - Frank Gladstone McLean
On 31 March 1962, in suburban Darlinghurst, the mortally wounded Frank McLean was found by a man walking with his wife and child. He was the victim of an unfinished assault committed by MacDonald. The man found McLean still breathing but bleeding heavily and went to get police.
On this day William MacDonald bought a knife from a sports store in Sydney. That night MacDonald left the Oxford Hotel in Darlinghurst and followed McLean down Bourke Street past the local police station. MacDonald initiated conversation with McLean and suggested they have a drinking session around the corner in Bourke Lane. As they entered Bourke Lane, MacDonald plunged his knife into McLean's throat. McLean tried to fight off the attack but he was too intoxicated to do so. He was then stabbed again in the face and punched—forcing him off balance. The assault was interrupted by a young family approaching. MacDonald hid himself on hearing the voices and the sound of a baby's cry. Once the man and his family had left to summon police, MacDonald returned to the barely-alive McLean, pulled him further into the lane and stabbed him again. A total of six stab wounds were inflicted. He then pulled down McLean's trousers, sliced off his genitals and put them into a plastic bag which he took home and disposed of the next day.
The police at one stage thought that the killer could have been a deranged surgeon. The manner in which McLean's genitals were removed seemed to be done by someone with years of surgical experience. Doctors at one stage found themselves under investigation.
