Instagram A human bone was found near the home of Nancy Guthrie in Arizona, but authorities are not connecting it to her case. The mother of Today host Savannah Guthrie has been missing since January 31 and police are still searching for her amid a suspected kidnapping. About seven miles from Nancy's home in Arizona, a human bone was found on Thursday (May 7), a spokesperson for the Tucson Police Department confirmed. The bone is not believed to be part of any criminal proceeding and is actually being investigated as a "prehistoric anthropological" finding.
