Foul play is not suspected in the case of the latest foot to wash ashore in B.C., the provincial Coroners Service says.

"These human remains did not show any evidence of trauma whatsoever," coroner Stephen Fonseca told a news conference Wednesday.

An 11-year-old boy spotted a left running shoe attached to a foot and part of a leg floating off a marina dock in Vancouver’s False Creek Tuesday evening.

The youngster notified Ron van Streun, who runs harbour cruises out of the marina.

Van Streun said he didn’t believe the boy at first but then retrieved the remains from the water and called police.

"The only thing we have ever seen in False Creek Marina is seals, the occasional sea otter and one whale," van Streun said.

Fonseca said his job now is to try to figure out who the remains belong to and how they got there.

Missing persons reviewed

"The police will also be providing us with suitable missing persons that we think are high priority and we will look at those cases," Fonseca said.

"If we need to obtain DNA samples from those family members, we will obviously pursue that as quickly as we can."

Fonseca said it's hard to tell how long the remains were in the water, but he suspects it's been a matter of weeks or perhaps months.

The discovery is the 11th finding of human remains in a shoe in waters on the West Coast since August 2007. A 12th purported discovery proved to be a hoax.

Some of the remains have been identified through DNA analysis, but the source of most of them is still not known.
