Genetic genealogist CeCe Moore tells PEOPLE, 'If I was the kidnapper, I would be extremely worried right now'

Investigators in the Nancy Guthrie case have turned to genetic genealogy as they try to make the most of potential DNA evidence.

A pregnant woman killed in 1980 was positively identified last month using DNA technology, the Ventura County sheriff said in a press release.

For many years, researchers believed that the DNA inside a newly fertilized egg began as a structural ‘blank slate’ – a loose, unorganized mass that would only take shape once the embryo started using its own genes. In this view, order emerged only after the genetic program switched on.

Kathleen Sheehan was “blown away” by Dottie’s DNA results, telling Newsweek: “Never in a million years would I have guessed that."

Pima County Sheriff Chris Nanos revealed that there are problems with the DNA evidence collected from Nancy Guthrie’s house that could take up to a year for the private Florida lab he’s using to resolve.

Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge,

“The weirdest combo is one set of grandparents was an Ovcharka and Pekingese cross,” the owner said. In the comments, the U.K.-based owner explained that the medium-sized, tan-coated dog was rescued through a charity that works specifically with dogs that have a bite history.
