Pima County Sheriff Chris Nanos got emotional while discussing the ongoing search for Savannah Guthrie's mom, Nancy Guthrie. "You have to have hope," Nanos said in an interview with NBC's Liz Kreutz, which aired via the Today show on Friday, February 6. "Come on, this is somebody's mom. We're gonna find her." Nanos got visibly emotional and choked up while explaining why he believes that 84-year-old Nancy is "still out there." Nanos confirmed in a press conference on Thursday, February 5, that authorities "have not identified a suspect or a person of interest" just yet.
