Overview
- The FBI is analyzing DNA from Nancy Guthrie’s Tucson home using newer lab methods after a Florida partner lab transferred the material this week, according to multiple reports Thursday.
- Pima County officials said the DNA from the scene contains material from more than one person, and Sheriff Chris Nanos warned the work to isolate a usable profile could take up to six months.
- NewsNation and other outlets reported the evidence includes hair collected in the home, and an FBI official told Extra the bureau requested the material over two months ago and only now received an original hair sample.
- Investigators say as many as five outside laboratories are assisting with the testing, and roughly two dozen Pima County and FBI personnel remain assigned to the case.
- Authorities report no matches in the FBI’s CODIS database from tested items to date, with porch blood confirmed as Nancy’s and DNA on a black glove found nearby producing no hits, while the sheriff’s office faced backlash after a confusing post that read “Nancy has been located” referred to a different missing woman.
