Digital Forensics Supports Nancy Guthrie Missing Person Probe

Investigators probing the Feb. 1 disappearance of 84-year-old Nancy Guthrie are leaning on digital forensics as the hunt continues nearly five weeks later, experts say. Authorities have recovered doorbell-camera images of a masked man and DNA from gloves with no CODIS matches, while the lab reported challenges for investigative genetic genealogy. Experts say analysis of phones, cloud logs, and social media could yield critical leads.
