New forensic developments have emerged in the case involving Nancy Guthrie, as the FBI reviews DNA evidence linked to her disappearance.
Sources told Fox News Digital that investigators have submitted DNA samples for advanced analysis, including hair recovered from Nancy’s Tucson home.
A spokesperson for the Pima County Sheriff’s Department confirmed ongoing cooperation with federal authorities.
“PCSD has worked with the FBI since the beginning of the Guthrie investigation. This is not new information,” the department wrote on Twitter.
“The private lab we use in Florida continues to share information with the FBI lab and other partner labs around the country. DNA analysis is ongoing,” he said.
Investigators had earlier said that DNA recovered from the scene had not yet identified any suspects in the alleged kidnapping of an 84-year-old man on February 1.
Experts say that analysis may take time. Genetic genealogist CeCe Moore said the hair sample was unlikely to be part of a mixed DNA sample.
“Not after cleaning it for contamination. Their process is in good shape, but it may take some time”, he said.
Authorities have also tested other evidence, including blood found at the home and a glove found nearby, but have had no breakthroughs.
