Arrest Made in Old Trails Fire Probe
Spokane County deputies arrested 37-year-old Aaron Farnaci on Monday in connection with the Old Trails Fire. The sheriff’s office said investigators executed both an arrest warrant and a search warrant in the city of Spokane. Officials booked Farnaci on a single charge of first-degree arson. The office also said a judge reviewed the affidavit before signing the warrant and set bond at $1 million.
The arrest came as crews kept battling destructive wildfires across Spokane County. Local reporting said the man was seen acting suspiciously near the fire’s origin before the arrest, and officials said the Old Trails Fire was determined to have been intentionally set. That matters because wildfire cases can move fast in public, but the proof often takes time. Investigators must protect the scene, interview witnesses, and build the case from evidence, not guesswork.
Why the Case Drew Attention
This case struck a nerve because wildfires hit hard, fast, and close to home. Families lose property, businesses face long shutdowns, and local law enforcement faces pressure to act quickly. When investigators say a fire was set on purpose, the public expects clear action. In this case, officials moved with a warrant, a search, and a formal arrest, which shows they believed the evidence had reached the probable cause stage.
That is the proper standard for an arrest, not a final verdict. A charge is still only a charge. Even so, the case highlights a larger truth that many readers know well: when criminal behavior threatens homes, land, and lives, the response must be firm and fast. Government cannot afford to dither while arsonists, vandals, or other bad actors put whole neighborhoods at risk.
Wildfire Investigations Depend on Evidence
Wildland fire guidance says every fire scene should be treated like a possible crime scene until the cause is clear. The aim is simple: determine the cause, identify possible responsible parties, and protect evidence before it is lost. That approach matters in arson cases because fire destroys clues while it spreads. If investigators move too slowly or lean on weak theories, the case can fall apart later in court.
Federal crime data in older arson research showed how hard these cases can be to solve and prove. One study found that only 19 percent of reported arsons were cleared by arrest in 1985, while another study found adult convictions in just 4 percent of cases. Those numbers are old, but they explain why investigators often work under heavy pressure. A strong arrest may be the first step, not the last one.
What Comes Next
Prosecutors now have to prove intent, origin, and cause in court. That will likely depend on witness statements, scene work, and any physical evidence collected during the search. If the evidence is solid, the case could become an example of law enforcement doing what many Americans expect: stopping destructive crime and holding the suspect accountable. If the evidence is thin, the case will have to stand on what can be proved, not what can be assumed.
For now, the key fact is clear. Spokane County authorities say they have an arson suspect in custody, and they believe the Old Trails Fire was set on purpose. In a year when western states still face serious wildfire danger, that kind of arrest sends a message that intentional fire setting will not be brushed aside.
