WINNIPEG - Winnipeg police say bones found by volunteers searching the Red River are not human.

Police said on Twitter that a forensic analysis by pathologists has confirmed the bones are from an animal.

Volunteers searching the banks of the Red River came across the bones earlier this week.

The group is combing the shoreline and dragging the bottom of the river, searching for clues about the fate of missing and murdered aboriginal women.

A blood-splattered pillowcase, a bloody rug and a set of dentures have also been turned over to police.

The group formed after the discovery of the body of 15-year-old Tina Fontaine last month.
