(Portland, OR) -- PacifiCorp has been found liable for causing four wildfires over Labor Day weekend in 2020. The Santiam, Echo Mountain, 242 and South Obenchain wildfires damaged or destroyed 25-hundred homes. Attorneys for the plaintiffs argued PacifiCorp's power lines started the fires during a high wind event and PacifiCorp should have turned off power. PacifiCorp's attorneys argued there's limited evidence that its power lines caused the fires. The U.S. Forest Service and the Oregon Department of Forestry haven't released the causes of the fires. The next phase of the trial will allow property owners to claim damages.
