Aaron Farinacci is currently being held in an Arizona jail as investigators continue to examine his potential ties to a Spokane-area blaze known as the Old Trails fire. Publicly available records and reporting identify a separate, earlier homicide from 2010 in which Farinacci was implicated in the death of his father; that incident forms part of the background now drawing renewed attention as law enforcement pursues leads related to the recent fire.

The recent developments have placed the older criminal matter back into public view and prompted reporting on Farinacci’s past. Officials have not provided a comprehensive public timeline tying the earlier killing and the more recent investigation together; what is on record is that the 2010 death of his father is a noted entry on his criminal record and that Farinacci is in custody in Arizona while Spokane-area authorities continue investigative work around the Old Trails blaze.
Investigators at the Spokane-area scene have been working to collect physical evidence from the structures affected by the Old Trails fire. Forensic teams have conducted searches of damaged homes and other locations within the burn area, cataloging material and documenting conditions that could be probative in determining cause. Photographs released by authorities show crews in protective gear examining charred interiors as part of a methodical evidence-gathering process.

Booking photographs circulated by law enforcement depict Farinacci in custody. Beyond the images, public statements and court records have provided limited details; law enforcement agencies typically withhold certain information during active investigations to preserve the integrity of ongoing work. The presence of a prior homicide on a person’s record, such as the 2010 killing of Farinacci’s father, can shape investigative and prosecutorial considerations, but officials have not disclosed whether those prior proceedings bear directly on current inquiries.
When a crime scene involves extensive fire damage, forensic investigators face specialized challenges. Burned structures often suffer destruction of potential physical evidence, and teams employ a range of techniques to identify accelerants, locate points of origin, and preserve trace materials. Documentation through photography, measurements, and chain-of-custody protocols is essential to maintain the evidentiary value of any items recovered. The images associated with the Old Trails response show personnel conducting these types of careful examinations amid the charred remains.
Criminal records that include violent incidents, including homicides, can affect subsequent legal processes for a suspect. Prior convictions or charges may be considered in pretrial hearings and can influence decisions such as bail, custody status, and prosecutorial strategy. However, each case proceeds on its own factual and legal merits, and prior incidents do not automatically determine outcomes in new matters. The public record in Farinacci’s situation identifies the earlier killing as part of his past, while current law enforcement action pertains to the fire investigation in the Spokane area.
At the time of reporting, authorities have held Farinacci in an Arizona facility while investigative work continues in the Spokane area. The details released so far are limited to his custody status, his criminal history that includes the 2010 killing of his father, and the active presence of forensic teams at the Old Trails fire scene. As criminal investigations move forward, law enforcement agencies and prosecutors typically release additional information selectively — often through formal statements, charging documents, or court filings — when doing so does not hinder investigative efforts.
The intersection of an older homicide case and a fresh fire investigation has prompted renewed media attention and public scrutiny. Forensic work at fire scenes and the processes that bring suspects into custody are procedural steps carried out by multiple agencies, from local fire marshals to county or state investigators and, when applicable, partnering federal authorities. In this instance, the focal points available to the public remain the record of the 2010 death of Farinacci’s father and his present detention in Arizona amid the Spokane-area Old Trails fire inquiry.
Further official information, including any formal charges connected to the Old Trails fire, court actions, or detailed investigative findings, would be disclosed through prosecutors’ offices, court dockets, or law enforcement media releases as the matter progresses. Until such documentation is made public, reporting on the case is limited to the recorded facts that include Farinacci’s custody status, his criminal record noting the 2010 killing of his father, and the ongoing forensic search of the fire-damaged structures in the Spokane area.
Spokane County Sheriff's Office investigators have formally charged Farinacci with first-degree arson; he is now held in the Spokane County Jail on $1 million bond after his initial court appearance. Court documents show a witness account from a child and grandfather, plus matches and a lighter found on him near the origin, helped secure the arrest, per reporting by CNN and KREM.
Court records and reporting say Farinacci shot and killed his father in Mesa, Arizona, in 2010 during an argument about washing dishes; he also shot himself but survived. He was originally charged with murder but pleaded guilty in 2012 to manslaughter and aggravated assault, served about a decade in prison and was released in 2020.
Court documents show Spokane investigators questioned Farinacci about two other fires last year though he was not charged in those incidents; deputies say they later located him on a park bench near the Old Trails origin appearing out of breath.
