The Case of Mikelle Biggs

On January 2nd, 1999, 11‑year‑old Mikelle Biggs walked outside with her little sister to wait for the ice cream truck. Minutes later, she was gone. Her purple bike lay on its side. The front wheel was still spinning. Two quarters were on the pavement. And no one saw what happened. This episode examines one of Arizona’s most haunting cold cases — a disappearance that unfolded in under two minutes, before AMBER Alerts existed in the state, and before modern child‑abduction protocols were in place. We explore the timeline, the investigation, the long‑standing person of interest, the myths that have grown around the case, and the family who has spent 25 years searching for answers. If you have information about the disappearance of Mikelle Biggs, contact the Mesa Police Department. Content Notes: Missing child, abduction, discussion of sexual violence (non‑graphic), long‑term unresolved cases.

Return to the Highway of Tears

Before the world knew the phrase Highway of Tears, families in northern British Columbia were already losing daughters, sisters, and mothers — and fighting to be heard. In this episode, we revisit the earliest known cases connected to Highway 16: Gloria Moody (1969), Helen Claire Frost (1970), and Tracey Clifton (1970s). Their stories reveal the roots of a crisis decades in the making. This episode explores investigative gaps, transportation inequality, and missing documentation — and honors the women whose stories shaped the foundation of this crisis.
