An 84-year-old woman disappears from her home, blood found on the doorstep. Foreign DNA is discovered inside the house, but it’s a mixed sample. And more than a month later, investigators still don’t have a suspect.

Nancy Guthrie Suspect Could Strike Again Soon, Says Ex-FBI Agent

In this episode of “The Truth of the Matter Podcast,” Natasha Zouves sits down with one of the most prominent genetic genealogists in the world, CeCe Moore, the forensic expert who has helped solve more than 300 cases using DNA.

Moore breaks down what investigators are really dealing with in the Nancy Guthrie disappearance, and why the DNA evidence may be far more complicated than the public realizes.

Among the revelations in this interview:

Moore believes the technology needed to separate the mixed DNA sample may not exist yet
Why police cannot simply search the largest 23andMe or Ancestry databases
The loophole investigators used in the Bryan Kohberger / Idaho murders case that no longer exists
Why Moore believes investigators should re-swab the Guthrie home right now
And why she believes the case could turn on the discovery of a second crime scene

Investigative genetic genealogy helped identify the Golden State Killer and helped lead police to Bryan Kohberger in the Idaho student murders. Moore believes genetic genealogy will solve this case — and talks about the path to get there.
