Authorities have shared more information about the disappearance of Savannah Guthrie's mom, Nancy Guthrie, including how the Today show star's own safety might be affected. "I don't think there's an active threat [to the public]," Pima County Sheriff Chris Nanos told reporters in a press conference on Monday, February 2. "We're going to canvass that neighborhood, maybe there's a prowler [that's] been seen around. There's a lot of work still to do. We don't have any indication that the public is still in danger.
