Whale researchers who track the small endangered population of Puget Sound orcas say three whales are believed dead or missing since summer. The Center for Whale Research says that as of Friday, Oct. 28, 2016, there are only 80 animals. Two females and a 10-month old calf are believed gone. (NOAA Fisheries/Vancouver Aquarium via AP, File
