The sheriff investigating the disappearance of “Today” show host Savannah Guthrie’s mother disputed that officials are still working through the evidence, in response to claims that it is a cold case.
Nancy Guthrie, 84, went missing in late January from her Tucson, Arizona-area home, while members of her family have repeatedly pleaded for her safe return. No suspects have been named, and no arrests have been made in the case.
