Authorities have confirmed that at least eight people died after a deadly mudslide destroyed homes near Oso, Washington, this weekend. Several people are reportedly still missing, and crews are attempting to secure the area. At least 30 homes were swept away by Saturday’s mudslide, believed to have been caused by heavy rainfall and groundwater saturation. Crews must search a debris wall — 15 to 20 feet deep in places — that state Gov. Jay Inslee described as “a square mile of total devastation.” He assured families that everything was being done to locate missing loved ones.
