VANCOUVER, British Columbia (Reuters) - Another severed human foot has been discovered washed ashore on Canada’s Pacific coast, but police are no closer to solving the gruesome mystery.

The foot, still wearing a shoe, was discovered on Thursday on a small uninhabited island south of Vancouver in the Strait of Georgia, and is the fourth discovered in the region in the past 10 months.

The previous cases all involved right feet still in sneakers, and each was found on a different island.

The Royal Canadian Mounted Police have not said if the latest discovery was a right or left foot.

DNA testing has failed to link the earlier discoveries to any missing person cases.
