Kootenai County, Idaho – Tension between rival vendors escalated dramatically at a weekend gold prospecting event, culminating in a backpack that caught fire and prompted a swift arrest. The incident unfolded on March 8, 2026, at the Kootenai County Fairgrounds, where attendees gathered for demonstrations and displays related to gold mining and treasure hunting.[1][2] No one suffered injuries, and the event proceeded without major interruption, but authorities uncovered materials inside the bag that raised serious concerns.[3]
Sudden Flames Disrupt Vendor Area
Around 1:15 p.m., deputies responded to reports of a fire inside a building at the fairgrounds. The son of one vendor approached a rival vendor’s table and tossed a backpack underneath it. The bag immediately ignited, producing smoke and what witnesses described as an explosion-like burst.[1] Someone quickly retrieved the burning item and hurled it outside, where it continued to smolder until emergency crews arrived.
The targeted vendor, David Peterson of Prospector’s Dream, maintained his setup amid the commotion. He later noted a past disagreement with the other party from two years prior but denied any fresh conflict that day. The fairgrounds management deferred questions to law enforcement, emphasizing the privately organized nature of the gathering.[3]
Roots of the Vendor Rivalry
The confrontation traced back to the previous day, March 7, when the two vendors clashed at the same event, known as the Northwest Gold & Treasure Show. Details of their initial dispute remained unclear, but it set the stage for the Saturday escalation. John P. Marsh, 21, from Midpines in California’s Mariposa County, emerged as the central figure. As the son of one vendor, he allegedly carried out the provocative act.[4][2]
Marsh’s family participated in the event, showcasing items typical of gold prospecting enthusiasts. Such gatherings draw hobbyists and professionals from across the region, fostering an atmosphere of competition alongside camaraderie. However, personal animosities occasionally surface, as this case illustrated.[5]
Accelerants Discovered in the Debris
Once the fire subsided, investigators examined the backpack closely. They located additional accelerants within it that had failed to ignite fully. This finding shifted the situation from a simple mishap to a potential criminal act, prompting specialized intervention.[1]
The Spokane County Sheriff’s Office Bomb Squad and Kootenai County Fire and Rescue neutralized any lingering hazards. Deputies from the Kootenai County Sheriff’s Office, aided by Coeur d’Alene Police, detained Marsh without resistance. The Bureau of Alcohol, Tobacco, Firearms and Explosives received notification for further support, underscoring the gravity of the materials involved.[3]

Sheriff Robert B. Norris’s office issued a statement confirming the facts and reassuring the public of the contained threat. The investigation extended to the vendors’ hotel in Coeur d’Alene, ensuring no further risks. Despite the drama, organizers confirmed the show wrapped up as scheduled, preserving the weekend’s focus on gold panning and metal detecting.[3]
