Evidence so far, from DNA to video, in Savannah Guthrie's search for mom

The Pima County Sheriff's Department said investigators continue to analyze evidence in the disappearance of Savannah Guthrie's elderly mother Nancy.

Law enforcement asks anyone with information to contact 1-800-CALL-FBI or tips.fbi.gov, the Pima County Sheriff's Department (520-351-4900) or 88-CRIME.

Authorities are assuring residents of southern Arizona and the world watching that the investigation into the disappearance of Savannah Guthrie's 84-year-old mother, Nancy, is far from over.

More than a month after Nancy Guthrie's suspected abduction, the Pima County Sheriff's Department said in a March 13 update that investigators continue to analyze evidence, including "material from laboratories as well as images and videos captured by camera."

"At this time, we will not comment on the details or status of this analysis," sheriff spokesperson Angelica Carrillo said in the update.

The sheriff's department, along with the FBI, has been looking into DNA samples collected from Guthrie's home and neighborhood in the Tucson area, a backpack worn by a suspect who "tampered" with her doorbell camera the night of her disappearance and a potential Wi-Fi jammer being used to interrupt Guthrie's internet service.
