SPOKANE, Wash. — A 37-year-old local resident with a prior violent criminal record was taken into custody on Monday, August 3, 2026, and charged with first-degree arson in connection with the catastrophic Old Trails Fire in Spokane County, Washington. Authorities identified the suspect as Aaron F. Farinacci, who is accused of intentionally starting the wildfire that rapidly swept through northwest Spokane. The inferno burned nearly 4,000 acres, destroyed approximately 700 buildings, and triggered mandatory evacuation directives for as many as 67,000 area residents. The arrest came after alert citizens provided critical witness reports to law enforcement, placing Farinacci at the exact location where the blaze originated.
The Old Trails Fire ignited on Saturday afternoon amid dry, windy conditions northwest of downtown Spokane. Witnesses contacted authorities after observing a man behaving suspiciously and kneeling in dry grass along the roadside where the flames first took hold. Law enforcement officers briefly questioned Farinacci down the road from the ignition point shortly after the fire began. However, responding officers initially released him at the scene to prioritize urgent lifesaving evacuations and traffic control as high winds pushed the flames toward populated neighborhoods.
Incendiary Evidence and Investigative Breakthrough
As major crimes detectives took over the scene and conducted forensic examinations of the fire's origin point, physical evidence confirmed that the blaze had been deliberately set using a match or lighter. Detectives re-evaluated the initial witness accounts and quickly re-identified Farinacci as the primary suspect.
On Monday afternoon, law enforcement officers located and apprehended Farinacci approximately four miles from where the fire started. During a search following his arrest, investigators discovered that Farinacci was carrying waterproof matches and a butane fuel lighter.
Spokane County Sheriff John Nowels commended community members for their proactive role in assisting the investigation, emphasizing that public alertness was the decisive factor in apprehending the suspect.
"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," Spokane County Sheriff John Nowels said during a news conference.
Echoing the sheriff's statement, local prosecutorial officials noted that community engagement provided the essential link needed to build the criminal case.
"It was through the work of vigilant citizens who were noticing things awry in their community, who were noticing things that were different and who took the time to engage with law enforcement to make sure the necessary information was shared," Spokane County Prosecutor Preston McCollam stated.
Violent Past: 2010 Arizona Manslaughter Conviction
Court records reveal that Farinacci has a significant violent criminal history in Mesa, Arizona, dating back to October 2010. At age 21, Farinacci shot and killed his father, Jeffrey Farinacci, inside their family home following a domestic argument over doing household dishes. According to law enforcement reports from that incident, Farinacci retrieved a handgun from a nightstand, fatally shot his father, pointed the firearm at his mother, and then inflicted a gunshot wound on himself.
Farinacci survived the self-inflicted wound and was initially charged with second-degree murder and aggravated assault. In 2012, he pleaded guilty to reduced charges of manslaughter and aggravated assault, serving a state prison sentence in Arizona before his release in 2020. Authorities noted that while Farinacci had no prior arson convictions on his record, he had previously been contacted by law enforcement for "arson-related behavior" in the region.
Devastating Regional Impact and Community Recovery
The Old Trails Fire quickly jumped the Spokane River over the weekend, consuming residential blocks, rural farm properties, and commercial structures. While firefighting crews took advantage of brief lulls in wind speeds to establish containment lines, hundreds of displaced families returned to find their homes reduced to ash and rubble.
Federal, state, and local emergency management agencies have mobilized resources to support displaced residents staying at regional emergency shelters. Meanwhile, Washington's congressional delegation requested an expedited federal emergency declaration to assist local government entities and uninsured property owners in recovery efforts.
What's Next: Legal Proceedings and Ongoing Inquiries
As emergency personnel continue mop-up operations across Spokane County, legal proceedings against Farinacci are advancing swiftly through the justice system:
- Court Appearance and Bail Determination: Farinacci was scheduled for his initial court appearance in Spokane County Superior Court, where prosecutors requested bail set at $1 million given his violent criminal history and flight risk.
- Formal Charging and Arraignment: The Spokane County Prosecutor's Office is preparing formal trial information for first-degree arson, with additional charges potentially under consideration as property damage assessments conclude.
- Origin and Cause Forensic Review: Fire investigators and federal ATF bomb and arson profilers are completing origin-and-cause documentation at the Old Trails Fire start site to finalize evidence for prosecution.
