Sunday, May 5, 2024 is recognized as Missing or Murdered Indigenous Persons Awareness Day across the United States. The date was selected because the Montana congressional delegation persuaded the U.S. Senate to pass a resolution declaring the national day of awareness because May 5 was the birthday of Hanna Harris, a 21-year-old member of the Northern Cheyenne tribe who went missing on July 4, 2013. On Friday, the White House released a presidential proclamation for Missing or Murdered Indigenous Persons Awareness Day, 2024.
