(CNN) - What was believed to be the sixth human foot to wash up on the shores of British Columbia in recent months was a fake, authorities said Friday. The British Columbia Coroners Service confirmed that the remains found in a shoe on Thursday were a "skeletonised animal paw" that was put in the shoe with a sock and packed with dried seaweed.
This goes down as one of the most bizarre stories I have ever been asked to report.
It's a mystery that began nearly a year ago, when a random foot was discovered on the shores of Canada. Soon, more followed.
Now, six feet in all have been discovered. All of them in the waters of the Georgia Strait area between Vancouver Island and the B.C. mainland.
The first two feet washed up in August 2007, one on Gabriola Island, the other on Jedidiah Island. Then in February another foot appeared on Valdes Island.
On Wednesday this week, the sixth human foot dressed in a running shoe was found.
It was discovered on a beach in Vancouver Island by a woman who was walking on the beach. The foot was still wearing a size 10 black adidas running shoe.
By now you're probably wondering, what the heck is going on?
Well you'll get the full report on Anderson Cooper 360 tonight, but here's what we know: Five of the feet found are right feet, including the one picked up this week. One of the feet discovered is a left foot, compounding the mystery.
Officials don't suspect foul play because it doesn't appear any of the feet were severed.
Investigators have far too many theories to list here but one of the more interesting ones is the feet may belong to victims of a plane crash. A plane, carrying four men, went down in 2005. Some of the bodies are still missing.
Dr. Gail Anderson, of the Simon Fraser University Centre for Forensic Research, says it's possible the feet belong to the missing bodies.
She told a local newspaper, "Perhaps a plane going down, a boat going down, where a number of deaths have occurred [could be the origin], perhaps something has happened. The tide has shifted, another boat has hit it, something has happened to move it."
Relatives of the victims have spent the past three years trying to find their remains, navigating a complex system of channels and currents and calculating where the tides may have taken the bodies.
The B.C. Coroner's Service has asked family members of the plane crash victims to provide further DNA samples to see if there's a match between their samples and DNA taken from three of the feet.
I'm wondering how far a severed limb can travel in the water? And why are just feet turning up? Also, if they're found still wearing socks and sneakers, has that helped preserve them and the DNA?
So many questions. We're going to get to the bottom of this mystery but if you have any ideas on where these feet may be coming from, I'd love to hear them.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
