Grant County Bombings | Cold Case Files | Episode 6

Author: NonStop Local June 9, 2026 Duration: 17:32
In August 2008, two Grant County men were killed just hours apart after unknowingly plugging in devices that had been rigged to explode.

William "Bill" Walker, a retired electrician, found a battery charger outside his shop and brought it inside. When he plugged it in, the device exploded. Less than 10 hours later, Javier "Harvey" Adame was killed when an explosive device hidden inside a police scanner detonated inside his home.

The victims appeared to have no connection. Investigators from the Grant County Sheriff's Office, FBI, and ATF determined the devices were likely built by the same person, but nearly two decades later, no arrests have been made and no suspect has been publicly identified.

Why were these men targeted? Were they the intended victims? And who planted the deadly devices that terrorized a rural Washington community? 

In this episode of Cold Case Files, NonStop Local examines one of the most baffling unsolved murder investigations in Inland Northwest history. If you have any information regarding the deaths of William Walker or Javier Adam, contact the Grant County Sheriff's Office at (509) 754-2011.

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.
