Spokane Wildfire Suspect Researched Best Weather Conditions to Ignite Blaze

Aaron Farinacci, 37, is charged with starting the Old Trails wildfire in Spokane, Washington, after planning the crime for weeks, researching optimal weather conditions, and using a homemade time-delay device, according to Spokane County court filings. The blaze was one of three major fires in the Spokane area that destroyed over 850 homes and forced tens of thousands of residents to evacuate. Farinacci faces five first-degree arson charges covering the Old Trails fire, four smaller blazes from the summer of 2025, and additional incidents from last month.

Planning the Spokane Wildfires and Weather Research

Police documents show that Farinacci meticulously prepared for the destruction. According to Spokane County Det. Michael Drapeau, the accused arsonist researched weather patterns to identify a day featuring high heat, low humidity, and strong winds. He ultimately selected Saturday, August 1, to ignite the Old Trails fire because winds in the area were forecasted to reach 80 km/h, as stated in court records.

Investigators stated that Farinacci constructed a “time delay device” utilizing notebook paper, matches, a cigarette, and a rubber band. Detective Drapeau noted that Farinacci purposefully carried cigarettes and marijuana to maintain a legitimate reason for possessing lighters and matches. “He knows arson is an easy crime to get away from if you have time, and he had time,” Drapeau said in the court filing.

Motive and Arrest Following Witness Report

During police questioning, Farinacci initially denied involvement before confessing to multiple fires, according to Detective Drapeau. When asked about his rationale, Farinacci expressed that “fire is powerful, beautiful, and that things that go through fire experience a kind of rebirth,” the detective recalled from their interview. While Farinacci admitted he knew the conditions “was gonna get bad,” he claimed to investigators that he did not intend for the Old Trails fire to expand to its eventual destructive scale.

Law enforcement intervention began thanks to a civilian tip. Paul Child, 64, spotted Farinacci standing near railroad tracks looking toward nearby trees while driving with his grandson. Child noticed the suspect remained in the brush acting nervous roughly ten minutes later. “You get the feeling this guy’s up to something,” Child told The Associated Press on Tuesday.

Legal Proceedings and Court Appearance

Farinacci was scheduled for an arraignment on five first-degree arson charges before Spokane Superior Court Judge Jeremy Schmidt. However, defense lawyer Colin Charbonneau requested a competency evaluation before his client enters a formal plea. Judge Schmidt stated he would review the evaluation request and ordered a $2 million US bond, citing concerns over community safety, a high flight risk, and the potential for a violent offence. Defence lawyer Charbonneau did not immediately return messages seeking comment.
