Surveillance video, genealogy key in Guthrie case

Investigators are utilizing genealogy databases to aid in solving the disappearance of Nancy Guthrie, following the discovery that DNA on gloves found near her neighborhood did not match national criminal records. This method has been successful in high-profile cases such as the Golden State Killer. Nancy Guthrie vanished from her home 19 days ago, with surveillance footage capturing a suspect on her porch the day she disappeared. The FBI is offering a $100,000 reward for information leading to an arrest.
