DNA Breakthrough in Guthrie Abduction

Nancy Guthrie was abducted from her Arizona residence in February, and the case has since become a focal point of national media attention.

Sources familiar with the investigation suggest that the new DNA evidence could finally identify a suspect or provide a lead into her current location.

The Pima County Sheriff has increased patrols in the neighborhood following reports that the Guthrie home has become a destination for 'ghoulish' tourists.

Savannah Guthrie recently returned to the 'Today' show, where she has received support from colleagues while her family continues to wait for answers.
