Sonali TiwaryAaron F. Farinacci, 37, was arrested on August 4, 2026, and charged with first-degree arson in connection with the devastating Old Trails Fire in Spokane, Washington. A judge set bail at $1 million. Farinacci was booked into custody after investigators linked him to the fire’s origin through witness testimony, geographic analysis, and evidence discovered during his detention.
The fire began on August 1, 2026, when the Old Trails Fire erupted in a populated area north of Spokane. A witness observed a man crouching near grass at the presumed fire origin location, suspicious behavior that prompted a call to authorities. The description provided by the witness proved crucial to the investigation.
Initial police contact occurred in the fire’s immediate aftermath. Officers detained Farinacci approximately half a mile from where the witness spotted suspicious activity. When searched, Farinacci was found in possession of waterproof matches and a butane lighter—items notably suited for deliberately starting fires even in damp conditions. Despite these suspicious findings, officers released Farinacci pending further investigation.
The decision to release him haunts investigators. On August 3, 2026, detectives matched the location where the witness had observed the crouching man to the geographically confirmed fire origin. Satellite imagery corroborated the witness’s observations. Cross-referencing with Farinacci’s known location and activities, investigators concluded they had sufficient evidence to arrest him for first-degree arson.
Farinacci’s criminal history complicated the investigation. He is a convicted felon, raising questions about his presence in areas where criminal records should have triggered surveillance or monitoring. However, investigators noted that while Farinacci had prior contact with law enforcement related to arson concerns, he had no previous arson convictions, making him potentially an unnoticed person of interest until this fire.
The Old Trails Fire became one of the most destructive wildfires in Washington’s recent history. The blaze consumed approximately 700 homes, leaving approximately 60,000 people displaced. The scale of destruction prompted statements from Washington Governor Bob Ferguson and appeals for federal disaster assistance. The fire’s intensity forced evacuations affecting entire communities north of Spokane’s urban core.
Investigators also pursued connections to two other Spokane-area fires—the Autumn Lane Fire and the Fairview Fire—to determine if Farinacci’s involvement extended beyond Old Trails. The pattern and timing of the fires suggested possible connections, though investigators emphasized that each fire remained under active investigation.
Wildfire prevention and arson prosecution have become increasingly critical as climate change extends fire seasons and residential areas expand into fire-prone regions. The Spokane case illustrates how community vigilance—the witness who reported suspicious activity—proved essential to apprehending a suspect. For disaster recovery efforts, identifying the fire’s cause through criminal investigation is a preliminary step. Long-term community resilience requires rebuilding infrastructure, restoring homes, and providing displaced families with support services.
