This week on BEYOND THE DARKLANDS, we take a look into the obsessed mind of violent girlfriend killer William Matheson.
In late 2003, William Matheson brutally murdered his ex-girlfriend, Lyndsay Van Blanken. He strangled the pretty 18-year-old with cable ties before dumping her body in an abandoned storeroom.
That same night he calmly played the cello in front of an audience of thousands. He showed no emotion.
Known for his bizarre behaviour, Matheson would spend nights wandering city streets scavenging for dead animals or sifting through rubbish.
Clinical psychologist Dr Leah Giarratano tells us what led this loner to turn from obsessed ex-boyfriend into a vicious killer. Did Lyndsay’s rejection of him turn him into a killer? Or was he always destined to inflict such unspeakable acts?
In Beyond The Darklands, interviews with those who knew them best – their family, friends, neighbours and teachers – as well as the police who investigated their crimes allows Dr Giarratano to dissect their personalities and ultimately offer some insight into why they committed these horrific crimes.
How did these fearsome criminals come to be – was it their upbringing, their influences or were they natural born killers?
