Michael Ruiz explains how DNA and IGG could advance Nancy Guthrie investigation

Fox News Digital reporter Michael Ruiz explains that more video might come out of Nancy Guthrie's house, especially since a new method to recover unrecoverable video has been developed. He highlights the significance of DNA found in the house and discusses how investigators might use Investigative Genetic Genealogy (IGG), similar to how Bryan Kohberger was caught, if the initial DNA database search yields no results.
