The man detained in connection with Nancy Guthrie's disappearance is speaking out, and insisting he's "innocent"! On Tuesday night, a DoorDash driver was taken in for questioning after a traffic stop as his mother-in-law's nearby residence was searched in Rio Rico, Arizona, about an hour from Tucson, where the 84-year-old went missing over a week ago. Police later released the man, and they have not said how they think he may have ties to the case.
