FBI Examines Fresh DNA Evidence In Nancy Guthrie Case

“Not after it is cleaned for contamination,” she said. “They have that process in good shape, but it can take some time.” She added of the sample: “I would assume it would be Nancy plus two or more unknowns.”

A spokesman for the Pima County Sheriff’s Department told Fox the police agency has “sharing a lot of things” with the FBI lab regarding Guthrie’s case.

“PCSD has worked with the FBI since the beginning of the Guthrie investigation. This is not new information,” the department wrote on X. “The private lab we utilize in Florida continues to share information with the FBI lab & other partner labs across the country. DNA analysis remains ongoing.”
