The investigation into the disappearance of Nancy Guthrie may have reached a critical stage, as the FBI is now closely analyzing DNA evidence recovered from her home.
According to reports, the DNA sample was collected earlier in the investigation but has recently been sent to federal authorities for more advanced testing.
Officials say the evidence is considered potentially crucial, though it comes with a complication that could slow progress.
Investigators have confirmed the DNA is a mixed sample, meaning it contains genetic material from more than one person, making it harder to isolate a clear suspect.
The FBI is now using newer forensic technology in an effort to separate the profiles and identify whether one of them belongs to the person responsible.
Nancy Guthrie, 84, has been missing since February after what authorities believe was a forced abduction from her home in Arizona.
Evidence at the scene, including blood and signs of disturbance, led investigators to treat the case as a serious crime from the beginning.
Surveillance footage has also reportedly shown a masked individual near the property, adding urgency to the search for answers.
While the DNA analysis could provide a breakthrough, officials caution that results may take weeks or even months due to the complexity of the sample.
The case remains ongoing, with authorities continuing to follow leads as the search for answers continues.
