The tense search for Savannah Guthrie’s mother is increasingly desperate with the purported kidnapper’s final deadline passing on Monday at 5 p.m. Law enforcement returned to Nancy Guthrie’s Tucson home over the weekend, searching the septic tank for items abductors may have flushed. Activity was also observed on the roof. Investigators removed a camera and a solar panel. Inside Edition spoke with former FBI special agent Lance Leising.
