Police searching for Nancy Guthrie, the mother of US news anchor Savannah Guthrie, have searched a property less than two miles from the 84-year-old's house. Police blocked a road and SWAT and forensic teams converged on the property near Tuscon, Arizona. Earlier, officials said investigators had found DNA at Nancy Guthrie's address which did not belong to her or people close to her. She disappeared in the middle of night from her home two weeks ago. #News #Channel4News #Guthrie #USA #Crime
