Pima County Sheriff Chris Nanos says Nancy Guthrie, Savannah Guthrie's mother, is "in danger" after going missing Saturday night. Nanos told Us Weekly the concern comes from what investigators learned about the scene at her home, calling it "something unusual." Search-and-rescue teams, drones and dogs are involved, along with volunteers, Border Patrol and the homicide team. Nanos also said she needs medication and going without it can be fatal.
