Nancy Guthrie Update: Expert Reveals What Could Complicate Ongoing Hair DNA Analysis

A DNA expert has shared insights into factors that could interfere with the hair analysis in the Nancy Guthrie case. The FBI is analyzing a hair sample collected in February, previously tested by a Florida lab used by the Pima County Sheriff's Department. Renowned genetic genealogist CeCe Moore notes that dyed hair can damage DNA, but current advances in technology may have addressed this challenge. Moore believes the case isn't cold and that the FBI will prioritize the analysis. The hair sample is reportedly rootless, but new technology can extract SNP profiles from it. Results may take months, but Moore is optimistic, having helped solve six cases using rootless hair alone.
