TUCSON, Arizona, Feb 17 (Reuters) - One of the most promising leads yet in the investigation into the abduction of Nancy Guthrie proved a disappointment on Tuesday when DNA from a glove found near her Arizona home failed to score a match in a national database of genetic profiles.
The outcome, announced by the Pima County Sheriff's Department and FBI, marked a major setback for investigators as the search for the 84-year-old mother of television journalist Savannah Guthrie stretched into its 17th day.
