Authorities have ruled out toxic algae as the cause of the mysterious deaths of a northern California family. John Gerrish, Ellen Chung, their daughter Miju, 1, and the family dog were found dead on a hiking trail near Hite’s Cove in the Sierra National Forest. Investigators were looking at whether exposure to chemicals from a nearby mine played a role. A Mariposa County Sheriff’s spokesperson says “there were no signs of trauma.” Inside Edition Digital has more.
