Late Friday night, the San Mateo County Coroner’s Office released the names of three of the at least four people who were killed. Two of the victims are mother and daughter — 44-year-old Jacqueline Greig and 13-year-old Janessa Grieg. Greig worked with the California Public Utilities Commission. The other victim has been identified as 20-year-old Jessica Morales. The name of the fourth victim has not yet been released, however Faye Wharton told ABC7 the body of her 80-year-old grandmother was found in the ruins of her home, which is right next to the explosion. She received word from authorities late Friday night. Her two aunts and uncle were also in the house. They made it out alive, but were severely burned.
