Autopsy unclear: Jonathan Gerrish, Ellen Chung, daughter Miju and dog die on California hiking trail

John Gerrish and Ellen Chung’s residence in Mariposa, Calif., was quiet on Aug. 16 when their 1-year-old daughter’s nanny arrived. The household — together with their canine, Oski — was nowhere to be discovered. Their truck was lacking, too. Because the hours wore on and not using a phrase from Gerrish or Chung, who had set out for a hike the day earlier than, a way of panic started to set in.
