The story made headlines across the world, with gruesome details of the case including McArthur hiding the body parts of his victims in planters in the home of a client earning him the moniker of the ‘Plant Pot Killer’.
People of any age can do terrible things, and to some extent, it’s useful to keep that in mind.
Another notable element of the case was the age of the perpetrator – McArthur was 67 when he was charged, decades older than we might expect.
In 2017, a total of 529 people were accused of homicide in Canada – only 27 were over the age of 60. While there’s evidence for this age bracket being among the least likely to act violently towards others, it can also mean the possibility of an older culprit can be wrongly written off.
“Because of the way that crimes are often depicted, especially violent crimes like murder, we have this image of young men whenever we think of killers,” Dr Shaw says.
“It does undersell, to some extent, the amount of crime and violent crime that is perpetrated by, not just against, older individuals. In some ways, I think that robs ageing adults of their agency if they’re only portrayed as victims - even for heinous things. People of any age can do terrible things, and to some extent, it’s useful to keep that in mind - not to villainize this part of the population but to that while age matters, you can commit a crime no matter how old you are.”
Along with his age, McArthur’s appearance also threw suspicion off him. His portly figure and long white beard reminded many of Father Christmas. He even filled in as the festive character at a shopping centre on at least one occasion. Chilling pictures show children smiling and sitting on his lap, with all but McArthur unaware of the heinous acts he’d committed.
