Savannah Guthrie's mom, Nancy Guthrie, has been reported missing in Arizona. "This is very concerning to us. We don't typically get the sheriff out at a scene like this. But it's very concerning what we're learning from the house," Pima County Sheriff Chris Nanos said in a press conference on Sunday, February 1. "And so we'll just continue. The detective's homicide team is out right now looking at the scene as well." A 911 call came through on February 1 with a family member calling the police to report 84-year-old Nancy missing. She was last seen between 9:30 p.m. and 9:45 p.m.
