New technology could help Nancy Guthrie case: Genealogist

(NewsNation) — A top FBI official clarified Monday the DNA evidence found at Nancy Guthrie’s home is not “new,” but the underlying technology may be key in making new headway in the confounding case.

On Friday, NewsNation learned DNA evidence, including hair, from Guthrie‘s home has been sent to the FBI’s lab for advanced analysis.

The evidence has already been tested through a Florida lab used by the Pima County Sheriff’s Office, but there is hope whole genome sequencing could lead to a breakthrough.

Genome sequencing extracts nuclear DNA from a sample, which could be blood, saliva or the shaft of a stray hair, meaning you do not need the root on the end. It was used to help break the case of Rex Heuermann, the Gilgo Beach serial killer.

Genetic genealogist Cece Moore told NewsNation, “Genetic genealogy came in 2018. The ability that Dr. Ed Green created to extract this profile from rootless hair is even newer than that. So it’s another leap forward that........
