My Left Foot

A human left foot was discovered partially submerged in the water near Westham Island in Ladner, B.C., Monday. It's the fifth human foot police have found in the province in less than a year. Four right feet, each wearing a sock and sneaker, have been discovered since August. A woman's right foot was found on uninhabited Kirkland Island in the Fraser River in May, just a few kilometres from where police found the fifth foot.
Three other men's right feet washed up in the Gulf Islands between Vancouver and Vancouver Island. In August, feet were discovered on Gabriola and Jedediah islands and, in February, another foot was found on Valdez Island.
Baffling isn't it? Is it ritualistic? Is it crazy? How could severed feet be turning up in Georgia Straight? Where are they coming from?
My deduction is that someone is dropping them into the Fraser river somewhere. Not too far or they might have been discovered farther upstream.
How does one obtain such a bizarre item for whatever reason? A person working in a mortuary would have access to human body parts. They could sever a foot of someone just before burial or cremation and it would be hard to discover.
But after who knows what secret ceremony?
Bizarre, but then the human mind has always had the capacity to be grotesque if you look closely enough.
