Toxic algae test results are in after mysterious deaths of California family while hiking
Few clues have been shared by investigators working to determine how a family and their dog died a little over three weeks ago while hiking in Sierra National Forest, in a remote section of Mariposa County southwest of Yosemite National Park. Known harmful algae blooms in the south fork of the Merced River, near where the family was mysteriously found dead along the Savage-Lundy Trail in Devil’s Gulch, are among the hazards being considered. … [But] investigators are “not saying” that’s what killed Mariposa residents John Gerrish, Ellen Chung, their daughter, Miju, and family dog, Oski.
