The Spokane County Sheriff’s Office said Aaron F. Farinacci, 37, was arrested and booked on suspicion of first degree arson in connection with the Old Trails Fire, the largest of three blazes burning around Spokane. Farinacci’s first court appearance will be Tuesday, according to Spokane County Prosecutor Preston McCollam. The Old Trails Fire sparked Saturday northwest of downtown Spokane, eventually jumping over the Spokane River and ripping through neighborhoods. Earlier Monday, some residents returned to find their homes leveled by wildfires that erupted across a parched landscape over the weekend, covering yards in charred debris. Mark Gregory, a spokesperson for the Spokane County Sheriff’s Office, said the county initially received nearly 300 reports of missing people, but by Monday they had cleared all but 14.
