More than two months after Nancy Guthrie's disappearance, investigators are still searching for answers. Experts say evolving DNA technology could yet provide a breakthrough in the case.
Genetic genealogist CeCe Moore outlined both the challenges and emerging possibilities tied to forensic analysis, saying mixed DNA samples remain one of the biggest hurdles.
Moore noted that advancements may come sooner than expected, and investigators are also exploring other avenues, such as a second crime scene, which could yield cleaner DNA evidence.
Chris Nanos, sheriff of Pima County, acknowledged the technical limitations investigators are facing, but expressed hope that DNA technology will resolve itself in the coming weeks or months.
Nancy, 84, the mother of Savannah Guthrie, was last seen at her Tucson home on the evening of January 31. Despite thousands of tips and a $1 million reward, authorities have yet to identify a suspect.
