SPOKANE, Wash. — Authorities have formally charged 37-year-old Aaron F. Farinacci with first-degree arson after determining that a human-caused open flame ignited the Old Trails Fire, the most destructive of three concurrent blazes that swept through Spokane County in early August 2026.
According to court filings submitted by the Spokane County Sheriff’s Office and wildland fire investigators, the blaze broke out on the afternoon of August 1, 2026, driven by high winds and low relative humidity. The fast-moving fire quickly burned through more than 3,600 acres of timber and dry brush, consuming roughly 700 structures, including residential homes, outbuildings, and commercial properties and forcing mandatory evacuation orders for approximately 67,000 residents across the metro perimeter.
Investigative reports establish that Farinacci was spotted acting suspiciously near the suspected point of origin shortly after the fire was first reported. According to sworn affidavits, a local resident reported seeing a man kneeling in dry roadside grass near railroad tracks. When deputies initially made contact with Farinacci a short distance down the road, a search of his fanny pack revealed a pack of cigarettes, a butane lighter, and a box of Gofire waterproof matches containing 14 remaining matches.
During initial questioning at the scene, Farinacci denied starting the blaze, telling deputies that he carried ignition devices solely "because he smokes". Furthermore, court records reveal that when Sheriff's Deputy Jerry Moffett later informed Farinacci that multiple witness accounts placed him directly at the ignition site prior to the outbreak, Farinacci retorted that those witnesses "don't know 'the whole thing.'"
Sheriff John Nowels praised community members for reporting the initial suspicious behavior near the roadside, emphasizing the role of public vigilance.
"As it happens in so many critical cases, it was citizens who were paying attention to their surroundings, being aware and willing to step up and say something that led to the relatively quick apprehension of Mr. Farinacci," stated Sheriff Nowels during a press briefing.
Farinacci’s criminal history includes a high-profile 2010 incident in Arizona, where he was convicted of manslaughter following the fatal shooting of his father, alongside previous arrests involving violent offenses and attempted murder charges. Sheriff Nowels also noted that while Farinacci lacks formal arson convictions, law enforcement agencies had previously contacted him for "arson-related behavior."

The Initial Release and Retrospective Case Building
While the formal arrest of a convicted felon with ignition tools near a disaster site provides a compelling narrative for public safety officials, legal analysts and skeptical observers point to a significant gap in the initial law enforcement timeline.
Records show that despite being detained near the fire’s origin with waterproof matches and a butane lighter in hand while the blaze actively expanded, Farinacci was interviewed by officers and initially released from the scene. Authorities prioritized immediate life-safety evacuations and traffic management over securing an immediate arrest, allowing Farinacci to walk away while fire crews fought the advancing front. It was only days later after major crimes detectives completed origin-and-cause analysis and re-interviewed eyewitnesses using body camera footage that law enforcement circled back to secure a formal arrest warrant 4 miles from the ignition site.
Skeptics argue that this procedural delay reveals a crucial operational detail: at the time of initial contact, law enforcement did not possess ironclad probable cause to hold Farinacci directly responsible for the ignition. Carrying incendiary devices like matches or lighters outdoors, while suspicious during a red-flag fire warning, is not inherently illegal, particularly for an individual who smokes. The necessity to build the case retrospectively using witness identifications after public outrage peaked over the 700 destroyed homes raises legitimate questions regarding whether early investigative momentum was driven by solid physical evidence or the convenience of a suspect with a heavy criminal record who happened to be nearby.
What's Next: Judicial Proceedings and Fire Recovery Operations
Farinacci is currently held at the Spokane County Jail on a $1 million bond pending his court appearances for first-degree arson. State prosecutors indicated that additional felony charges could be considered as damage assessments continue across the affected neighborhoods.
Concurrently, regional disaster assistance teams and wildland fire units remain engaged in mop-up operations across the 3,600-acre burn scar, working to clear hazardous debris and verify infrastructure stability before displaced residents are fully cleared to return to destroyed residential properties. For hundreds of families, returning home has meant confronting total destruction.
"There's nothing to save," said 76-year-old resident Miriam Sim as she surveyed the ashes of her home. "At our age, do we want to rebuild?"
