Firefighters are looking for whoever is starting fires along the greenway after they put out the fifth along the path in recent months. Jeff Pfaff with the Yakima Fire Department said natural brush fire in Yakima are not unheard of, but after so many along the greenway this summer he’s sure that someone is sparking these blazes. "We haven't had a significant event like weather or we don't have power lines in the area so these are definitely suspicious in nature and somebody is out lighting these fires," he said. While the fires have remained small in size, the area gives firefighters problems because of how narrow the path is and a lack of water options once they're there. He also said these small fires take away resources from other emergency situations.
