My money is on a plane that crashed en route to a left-leg amputees’ convention…

From today’s Seattle P-I, news that, for the fourth time this year, a severed right foot has been found along the coast of British Columbia:

Police said a passer-by found a human foot Thursday in a shoe on Kirkland Island in the South Arm of the Fraser River.
“It’s certainly a mystery we intend on solving,” police Constable Annie Linteau said. “It’s certainly very unusual.”
Last August, a foot was found inside a man’s Reebok sneaker on nearby Gabriola Island, just a few days after another foot was discovered by beachcombers on Jedidiah Island.
The remains of a fourth right foot were found Feb 8 on the east side of Valdez Island.
There is no evidence to suggest that the foot — or any or the previous three — was forcibly removed, Linteau said. “All four were wearing socks and were in a running shoe…”
B.C. Chief Coroner Terry Smith said DNA profiles have been taken from the first three feet. He could not comment on the investigation or the new finding.
The fourth foot is now at his office, Linteau said.
