On June 2017, somewhere within the 1.5 million acres of the Blackfeet Indian Reservation in northwestern Montana, 20-year-old Ashley Loring Heavy Runner vanished. Her sister, Kimberly Loring, describes the ongoing pain: “I can look at her picture and feel totally broken. It feels like it just happened. I continuously think of my sister every day.” Ashley’s disappearance did not just shatter her family—it set Kimberly on a years-long mission that would take her from the wilds of Montana to the offices of U.S. Senators on Capitol Hill. This preview of Dateline: Missing In America Season 5 introduces Ashley’s case as one of six new unsolved mysteries the podcast hopes listeners might help crack.
