Fox News correspondent Matt Finn reports on updates in the search for Nancy Guthrie, now entering week three. Former FBI supervisory agent James Gagliano also joins 'America's Newsroom' to weigh in on the investigation. The FBI has received DNA evidence recovered from the Tucson, Arizona, home of Nancy Guthrie, including test results from a hair sample, sources familiar with the investigation told Fox News Digital. A source with knowledge of the investigation confirmed that investigators had collected DNA, including hair, from Guthrie's home and shared it with the FBI. It was expected to undergo more advanced testing. CeCe Moore, a leading investigative genetic genealogist at Parabon Nanolabs, said a hair sample is unlikely to be part of the mixed DNA sample investigators were having trouble with."Not after it is cleaned for contamination," she said.
