MONTREAL — The mystery has haunted Canadians for more than a decade: One by one, human feet clad in running shoes have floated ashore on British Columbia’s southern coast with gruesome regularity.

Last weekend, foot No. 14 was discovered by a man strolling on a beach on Gabriola Island, a sleepy and picturesque enclave, population 4,000, that is known for its captivating sandstone and close-knit artistic community.

This time, the foot, squeezed between a pile of logs, wore what appeared to be a hiking boot, according to the Royal Canadian Mounted Police.
