One person was injured in the first of four fires that burned in Yakima from Tuesday night to Wednesday afternoon. Firefighters were called to the 200 block of Oak Street at 11:28 p.m. Tuesday for a fire that started in a tree and spread to a six-plex, according to a fire department news release. While only the building’s siding and a vehicle parked in the area were damaged, a man with a second-degree burn on his arm was treated at the scene, the release said.
