The Banks of Two-Medicine: The Disappearance of Arden Pepion

June 10, 2026 / Laurah Norton

n April of 2021, three-year-old Arden Pepion was taken to a shooting range on the banks of the Two-Medicine River on the Blackfeet Nation reservation in Montana. She hasn’t been seen since—and despite years of search efforts, her family still doesn’t have an answer. What happened to Baby Arden? In the first of a two-part series, we cover her disappearance and the experiences of her paternal grandmother, cousin, and MMIP advocate Rhonda Grant Connelly.
