The FBI is analyzing DNA evidence recovered from the Tucson, Arizona home of Nancy Guthrie, according to sources familiar with the investigation.

The evidence includes material collected from Guthrie's residence following what sources described as an abduction. The FBI recently received the DNA samples and has begun advanced analysis of the materials.

Guthrie is identified as the mother of television personality Savannah Guthrie. The investigation centers on her Tucson home, where the DNA evidence was reportedly collected.

The FBI has not publicly commented on the specifics of the case or the nature of the DNA analysis being conducted. Sources did not provide details about the timeline of the alleged incident or current status of the investigation.

DNA analysis in criminal investigations can take weeks or months to complete, depending on the complexity of the samples and laboratory capacity. The FBI's laboratory services handle thousands of DNA cases annually for federal, state and local law enforcement agencies.
