The Mutilator - The William MacDonald Story

In November 1962, a foul smell drifting through a quiet Sydney
street led police to a discovery that would quietly conceal one
of Australia’s most disturbing serial killers.


What they found beneath the floorboards of a small delicatessen
seemed straightforward at first. A dead man. A closed case. A
name on the paperwork: Alan Brennan.


But there was one problem.


Alan Brennan didn’t exist.


He was an alias used by William MacDonald — a man already
responsible for a series of brutal murders across Sydney and
Brisbane. While police believed the killer was dead and buried
under his false identity, MacDonald was still alive… walking
free… and planning his next attack.


Nicknamed “The Mutilator”, MacDonald’s crimes
would span cities, identities, and multiple victims before an
extraordinary mistake exposed the truth: investigators had buried
a victim under the killer’s name, allowing him to vanish in plain
sight.


This episode traces MacDonald’s life from troubled beginnings to
a devastating series of killings, the investigative failures that
allowed him to evade capture, and the unlikely encounter that
finally brought one of Australia’s most feared killers to
justice.


A story of deception, missed connections, and one of the most
bizarre errors in Australian criminal history.
