Arson suspect eyed in Old Trails Fire as witness speaks out

Fox News is reporting that investigators are focusing on an arson suspect in the Old Trails Fire after a Washington grandfather said he saw a stranger near railroad tracks just before smoke rose in Spokane County. The account is emerging as authorities work to pin down how the blaze began and whether it was deliberately set.

The Old Trails wildfire has already become a flashpoint in eastern Washington, and the new witness detail raises urgent questions about rail corridors, fire risk and accountability as the region moves through another volatile fire season.

What Fox News is reporting about the Old Trails Fire

According to Fox News, the most recent development in the Old Trails Fire investigation is a focus on a possible arson suspect. The report, dated August 6, 2026, centers on a Spokane County grandfather who says he spotted a stranger by nearby railroad tracks moments before he saw smoke rising from the area now burned by the blaze.

That timeline, as described to Fox News, is drawing attention because it links human activity along the tracks directly to the first visible signs of the wildfire. In an investigation that must sort accident from intent, that single observation gives officials a specific location, a window of time, and a description of behavior to work from as they review how the Old Trails Fire started.

“A stranger by the tracks, smoke on the horizon, and a wildfire that now has its own arson suspect.”

The witness account from the Spokane County grandfather

The grandfather told Fox News he noticed a person he did not recognize near the railroad tracks, and shortly after that, smoke began to rise where the Old Trails Fire would soon erupt. His story matters because it suggests a possible ignition point that was not tied to lightning or a visible equipment failure, but instead to a stranger on foot in a sensitive corridor.

Rail and utility corridors in fire‑prone parts of Washington often cut through dry vegetation, so any sparks, open flames, or risky behavior can quickly escalate. The witness says those few minutes between spotting the stranger and seeing smoke were enough to raise his suspicion, and his decision to speak publicly now adds pressure for a full accounting of what was happening along the tracks at that moment.

How an arson suspect changes the Old Trails Fire investigation

Labeling anyone an arson suspect shifts an inquiry from questions of weather and chance to questions of motive and method. In the case of the Old Trails Fire, Fox News reports that an individual is now accused of setting the Spokane County blaze, which means investigators are likely reconstructing movements near the tracks and comparing them with the grandfather’s description and timeline.

An arson focus usually prompts closer examination of surveillance cameras, train schedules, and any reports of trespassing or unusual activity in the same span of minutes the witness recalls. Even without public details on charges or evidence, the basic fact that a suspect has been identified signals that authorities believe the fire could have been preventable, and that criminal accountability is on the table.

Why railroad tracks are under scrutiny in Washington wildfires

The detail that the stranger was spotted near railroad tracks is not incidental. In eastern Washington, tracks often run past fields, brush and timber that can dry out in summer heat. That makes any activity along the right‑of‑way especially sensitive once fire danger rises, whether the cause is mechanical, accidental or intentional.

The Old Trails Fire now fits into a wider concern about how linear infrastructure, including rail, intersects with wildfire risk. If investigators confirm that the blaze began along the tracks where the grandfather says he saw the stranger, it would reinforce how small moments of negligence or malice in those corridors can have serious consequences for nearby communities in Spokane County.

What to watch next in the Old Trails Fire arson case

With Fox News reporting that an arson suspect is accused of setting the Old Trails Fire, the next phase will be about verification and process: whether authorities release more on the suspect’s identity, what evidence they say ties that person to the ignition point, and how the witness account factors into any formal case. Residents who lived through the smoke and disruption will be looking for answers about how close the fire came and whether systems meant to protect them worked as intended.

For anyone following the broader pattern of Western wildfires, this case is a reminder that human behavior remains a central variable even in a changing climate. Spinn Radio will track how the investigation unfolds, how local officials respond, and what this might mean for fire prevention policy in Spokane County and across Washington.
