The frantic search for Savannah Guthrie’s 84-year-old mother, Nancy, who went missing from her Arizona home on January 31, has taken a troubling turn.

According to the Los Angeles Times, police have reportedly uncovered alarming evidence that is raising serious concerns about her safety.

Possible kidnapping or abduction

Authorities are growing increasingly concerned for Nancy Guthrie, the 84-year-old mother of Savannah Guthrie. She was last seen in her home in the Catalina Foothills, north of Tucson, Arizona, on Saturday.

“It is a race against time, and I hope that window hasn’t closed,” Pima County Sheriff Chris Nanos told NBC’s Liz Kreutz during a segment for the Today show aired Tuesday, Feb. 3.

Nancy, a mother of three, was reported missing by her family and investigators in Arizona say they currently have no solid leads, urging the public to come forward with any information.

The police believe that Nancy has been forcibly taken from her home in what authorities are describing as a “possible kidnapping or abduction.”
