Arson arrest marks a significant development in the investigation surrounding the destructive Old Trails Fire near Spokane, Washington. Investigators continue collecting evidence while examining the circumstances that led to one of several major wildfires affecting the region.
Authorities arrested 37-year-old Aaron F. Farinacci on Monday in connection with the Old Trails Fire investigation. Detectives developed probable cause after reviewing evidence gathered during the early stages of the case. Investigators from the Spokane County Sheriff’s Office worked alongside the Washington Department of Natural Resources throughout the investigation. Their coordinated efforts led to the suspect’s arrest without reported resistance.
Officials said community tips played an important role during the investigation. Information provided by Airway Heights police officers and Spokane County sheriff’s deputies also helped detectives establish probable cause. Investigators reviewed witness statements alongside evidence collected from the wildfire scene. Consequently, authorities secured both an arrest warrant and a search warrant before taking further action.
Law enforcement officers served the search warrant at Farinacci’s residence on Monday. Deputies completed the operation without incident before placing him into custody. During the search, investigators recovered a butane lighter and waterproof matches. Authorities included those items as part of the ongoing criminal investigation. Farinacci now faces a first-degree arson charge while remaining in custody.
Officials stated that Farinacci previously lived in Arizona and has a felony conviction. However, investigators reported finding no documented criminal history involving previous fire-related offenses. Detectives also emphasized that the investigation remains active as they continue reviewing additional evidence. Therefore, authorities have not ruled out further investigative developments.
Sheriff John Nowels explained that first-degree arson represents the charge currently supported by available evidence. He also noted that investigators will continue evaluating all facts as the case progresses. Additionally, officials plan to examine whether the suspect may have committed any other related offenses. Investigators stressed that future charges could depend upon newly discovered evidence.
Authorities have not connected Farinacci to the Autumn Lane Fire or the Fairview Fire. Investigators continue treating those wildfires as separate incidents while pursuing independent investigative efforts. Law enforcement agencies remain focused on determining the exact causes behind each blaze. Consequently, officials continue gathering evidence across multiple wildfire scenes.
Arson arrest follows days of widespread destruction caused by several fast-moving wildfires throughout the Spokane region. The Old Trails Fire became the largest wildfire among the three major incidents. Hundreds of homes, businesses, and other structures suffered damage or complete destruction during the emergency. Meanwhile, evacuation orders affected approximately 67,000 residents across several communities.
More than one thousand firefighters continue battling the wildfires under difficult weather conditions. High temperatures, prolonged drought, and strong winds have complicated suppression efforts across affected areas. Emergency crews remain focused on protecting lives, homes, and critical infrastructure throughout the region. Officials continue monitoring fire behavior while expanding containment operations.
Arson arrest represents an important milestone, but investigators emphasize that the criminal investigation remains ongoing. Washington officials continue gathering evidence while firefighters work to contain the remaining active wildfire threats. State leaders have also declared a wildfire emergency and implemented temporary restrictions on most outdoor burning through the end of September.
