Pima County Sheriff Chris Nanos revealed he suffered a personal tragedy amid the search for Savannah Guthrie's missing mom, Nancy Guthrie. Nanos told the Daily Mail on Sunday, February 15, that his brother died in hospice one day after Nancy, 84, was reported missing in Tucson, Arizona, on February 1. Amid his own period of grief, Nanos acknowledged the criticism he has faced from the public about how he's been handling the investigation. "People out there can get pretty ugly and mean and nasty and not have the facts," he told the outlet.
