Sault Tribe's Advocacy Resource Center (ARC) hosts an event each year to promote awareness for missing and murdered indigenous women and relatives. May 5 is most widely recognized in the United States and Canada as Missing and Murdered Indigenous Persons Day. Research published by the National Institute of Justice indicates that more than four in five American Indian and Alaska Native women have experienced violence in their lifetime. This includes stalking, sexual violence, and physical abuse by an intimate partner.
