 The Multnomah County Medical Examiner continues to investigate a series of deaths believed to be related to the recent heat wave. Another person was found dead in Portland Tuesday, a 72-year-old man. That takes the number of suspected heat-related deaths to six. Five were from Multnomah County, and the other was a Clackamas County man who died at a Portland hospital. The Oregon Coast Aquarium has proposed a new license plate to help support marine wildlife rehabilitation.
