Authorities investigating the disappearance of “TODAY” co-anchor Savannah Guthrie’s mother on Thursday provided a timeline of the night she went missing as the search for her stretched into a fifth day. Officials had been searching using drones, a helicopter, an airplane, search-and-rescue dogs and volunteers before the search was called off on Feb. 2 due to police viewing her disappearance as a crime investigation. #savannahguthrie #today #mom #update
