SAVANNAH GUTHRIE MOM MISSING: DAY 13

On day 13, in the search for Nancy Guthrie, we have seen an increased reward and a turf war exposed between Pima County investigators and the FBI. Sheriff Chris Nanos says he has not been blocking FBI access to evidence, even though we learn that the sheriff's office sent evidence, including gloves found inside Guthrie's home, to a Florida lab, not the FBI lab. Nanos says it's not even known if the gloves were connected to Guthrie's disappearance. New video posted to social media of a man ringing the doorbell of a homeowner 6.5 miles from Gutherie's home at 5 am. The homeowner did not know the man. The FBI is not saying the man is involved, but is looking at all tips submitted.
