A fourth death in Umatilla County is also suspected to be linked to the heat wave. Three others reported in Marion and Clackamas counties may also be heat-related, including an incident where an elderly man was found dead inside a home that didn’t have a working air conditioner, however, the final determination of cause of death has yet to be made, KGW reports.
