Morbid Fact Du Jour For June 13, 2017

Today’s Psychopathic Yet Truly Morbid Fact!

The “Sydney Mutilator”, William MacDonald, is considered Australia’s first serial killer. Between 1961 and 1962 MacDonald terrorized Sydney with a string of gruesome murders before being apprehended while working as a porter at Melbourne’s Spencer Street railway station on May 13, 1963. His modus operandi was to select his male victims at random (mostly derelicts), lure them into a dark place, violently stab them dozens of times about the head and neck with a long bladed knife, and finally sever their penis and testicles. 

The Sydney Mutilator.  Doesn’t slip off the tongue quite as nicely as the “Boston Strangler,” does it?

MacDonald described the murder of his last victim, Patrick Hackett, picked up while drinking at a Melbourne hotel. He woke up in the middle of the night and picked up a knife. “As I stood looking at him, with the knife grasped firmly in my hand, a mad rage came over me. I knelt down and stabbed him in the neck… I struck down at him again and again. During the stabbing, I accidentally struck my own hand, and then I lost count of how many times I thrust the knife into his body. Even after I knew he was dead, I kept on plunging the knife into him.”

This description certainly suggests that Macdonald may have had some form of seizure. Many criminal activities are associated with a brain-wave known as the theta rhythm. These waves were first noticed in young children [I’m not surprised – DeSpair], and they became pronounced when the child experienced emotions of pleasure or pain.

Theta rhythms could be easily evoked in a small child by offering a sweet and then snatching it away. [Can I sign-up to run this study? – DeSpair] In adults, these rhythms play a very small part – except in aggressive psychopaths. Dr. Grey Walter comments about this sudden murderous violence towards other people in animals: “These destructive or murderous episodes are often almost or completely unmotivated by ordinary standards.”

This is not, of course, to suggest that psychopathic violence – like Macdonald’s – is caused in some way by theta waves as an epileptic attack is caused by an electrical discharge. Possibly the theta waves appear when the psychopath induces a certain state of mind in himself. Macdonald had decided to kill the man before he went to sleep, and the “blind rage” came over him after he had picked up the knife. He had somehow triggered the attack in the way that a normal person can trigger sexual excitement by directing the thoughts towards sex. 

But all this – like the discoveries about the amygdaloid nucleus in the brain, the source of our aggressive instincts – suggests that many violent killers may be suffering from some physical imbalance of the same kind that makes some people abnormally active and others sluggish and dull [You called? – DeSpair]. And it could be connected with the kind of hormone activity that turns some women into nymphomaniacs and some men into “satyrs”.
