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. Together, the fires have destroyed at least 700 buildings and forced some 67,000 people to evacuate. Farinacci’s first court appearance will be Tuesday, according to Spokane County Prosecutor Preston McCollam. 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. At least 390 square miles (1,000 square kilometers) has burned across Washington, which has contended with severe drought and a paltry snowpack.
