The man accused of igniting a destructive wildfire near Spokane, Washington, had been questioned last year in connection with two other fire investigations, according to court documents. Aaron Farinacci, 37, of Spokane, now faces first-degree arson charges for allegedly starting the Old Trails fire, one of three major blazes burning in Spokane County. He was arrested Monday and is being held on $1 million bail.
Suspect's Prior Contact with Law Enforcement
Court records reveal that Farinacci was questioned in July and August 2025 regarding several small fires near the Spokane River, close to his apartment. During one investigation, police searching for a wildfire suspect at a state park encountered Farinacci sitting on a bench, appearing out of breath, possibly from running. Officers photographed him, noting he wore a green T-shirt similar to the one seen in surveillance footage from Saturday's fire.
Despite being questioned in those cases, he was not charged. However, the new arrest has brought his criminal history to light. Farinacci served roughly a decade in prison for manslaughter and aggravated assault in the 2010 killing of his father in Arizona. He was released from probation in early 2024, though he had not completed a mental health evaluation or domestic violence treatment, according to his probation officer.
Witnesses and Evidence
Authorities say witnesses identified Farinacci near the origin of the Old Trails fire. Paul Child, who was driving with his grandson, told the Associated Press, "He was bent over in the brush, acting nervous. You get the feeling this guy's up to something." Farinacci allegedly had waterproof matches, cigarettes, and a butane lighter in his possession. Investigators ruled out other causes before arresting him.
Farinacci denies setting the fire. His arrest comes as the region battles an "extraordinary" fire season, with extreme heat, drought, and limited resources fueling dozens of large blazes across Washington.
Firefighting Progress and Challenges
The three fires around Spokane have scorched more than 10,000 acres. Cooler weather and higher humidity have aided firefighters, allowing them to establish containment lines. Crews are now strengthening these lines, preparing for the return of critical fire weather later this week and into the weekend.
Spokane County Sheriff John Nowels confirmed that Farinacci was first questioned shortly after the Old Trails fire began, based on witness reports of him kneeling in brush near the ignition point.
Community Impact
The Old Trails fire has destroyed homes and forced thousands to evacuate. In a residential community, chimneys now stand where houses once did, a stark reminder of the fire's devastation. Officials urge residents to remain vigilant as conditions could worsen.
Farinacci's bail is set at $1 million, and he remains in custody. The investigation is ongoing, and further charges may follow as authorities continue to assess the full extent of the damage.
