Nancy Guthrie update: DNA couldn't be profiled from crime scene hair sample, sheriff says

DNA testing on a hair found in Nancy Guthrie's home returned no profile, but investigators say the sample may still prove valuable as the case continues.

Hair found in the Arizona home of Nancy Guthrie is not linked to any potential suspects in her disappearance, federal law enforcement officials said Thursday.

Nearly six months after Nancy Guthrie was kidnapped from her home in Tucson, Arizona, Jonathan Vigliotti sat down with the sheriff at the forefront of the investigation.

Two persons of interest detained after Guthrie vanished were released on legal grounds — not because they are definitely innocent, Chris Nanos insisted.

That leaves a mixed sample of DNA retrieved from the home as the only known piece of biological evidence in the case.

Pima County Sheriff Chris Nanos released a statement Thursday marking six months since the disappearance of Nancy Guthrie from her Arizona home.

Sheriff Chris Nanos responded to FBI Director Kash Patel's claims about federal agents being excluded from the Nancy Guthrie investigation.

Sheriff Chris Nanos say FBI Director Kash Patel was "misinformed" and revealed the two have never spoken.
