Author: NonStop Local May 12, 2026 Duration: 17:03
The July 1990 murder of 18-year-old Toni Tedder remains one of the most haunting unsolved cold cases in Clarkston, Washington and one of the Pacific Northwest’s enduring murder mysteries. Toni had just graduated from Clarkston High School and was sleeping on her family’s living room couch when she was stabbed to death while family members slept nearby. Investigators say a wood-handled fishing fillet-style knife was left near Toni Tedder’s body, and questions surrounding the unsolved Clarkston murder investigation continue decades later. Was Toni Tedder the victim of a random attack or a targeted killing, and why has the case never been solved despite witness accounts and physical evidence?

In this episode of Help Me Hayley: Cold Case, Hayley Guenthner speaks with Clarkston investigators and retraces the timeline of the 1990 Toni Tedder murder searching for clues that could finally help connect the community to justice.

Beyond the headlines of the daily news cycle lie stories that have lingered for years, sometimes decades, in the shadows of the Inland Northwest. Help Me Hayley: Cold Case Files is a podcast that brings those stories back into the light. Guided by NonStop Local journalist Hayley Guenthner, this series digs into the details of Spokane's most notorious and often forgotten unsolved crimes. Hayley's experience isn't just from a script; when she's not anchoring weekend newscasts, she's on the ground producing investigative pieces and covering crime across the region. That firsthand perspective shapes every episode. Listeners will hear a careful examination of the facts, the timelines that don't add up, and the lingering questions that haunt families and investigators alike. This isn't about sensationalism; it's about a persistent search for clarity. Each case is presented with a journalist's rigor and a local's understanding, piecing together historical records, past reporting, and the human impact that remains fresh. The goal is to give voice to stories that deserve answers, exploring the complexities of investigations that have grown cold and remembering the lives at the center of them all. Tune in for a thoughtful, deep dive into the region's past, one unresolved mystery at a time.
