The backstory:

Nancy, who is the mother of “Today” show co-host Savannah Guthrie, was last seen on the night of Jan. 31 after being dropped off at her Catalina Foothills home near East Skyline Drive and North Campbell Avenue. She was reported missing the next day after her family was notified that she hadn’t shown up for church.

Authorities say she was taken from her home against her will and is without her necessary medication. Photos taken at the scene show blood drops on the porch of Nancy’s home.

On Feb. 11, FBI officials said they were “conducting an extensive search” along roadways in the Catalina Foothills area near Guthrie’s home.

“Numerous FBI agents are conducting an extensive search along multiple roadways in the Catalina Foothills area related to the Nancy Guthrie investigation,” the FBI’s Phoenix field office said in a statement. “We are asking the medi and motorists to follow all traffic laws and to remain especially cautious when passing law enforcement personnel near the roadways.”

On Feb. 12, the Pima County Sheriff’s Department asked residents within a two-mile radius of Nancy’s home to submit “all video footage that includes vehicles, vehicle traffic, people/pedestrians, and anything neighbors deem out of the ordinary or important” from Jan. 1 to Feb. 2.

On Feb. 13, PCSD said that DNA other than Nancy’s and “those in close contact to her” were collected from the property, and investigators are working to identify who it belongs to. PCSD is not saying where the DNA was located.
