A Spokane County detective who interviewed the man accused of starting one of the city’s wildfires says the man confessed, described his planning process and explained how he created a device to ignite the blaze.

Aaron F. Farinacci was booked on suspicion of arson in connection with the Old Trails Fire.

The suspect was arrested in connection with one of three wildfires in Spokane, Wash., that have destroyed hundreds of homes and displaced nearly a quarter of the city's residents.
