Today” show host Savannah Guthrie's brother on Thursday renewed the family's plea for their mother's kidnapper to contact them, hours after an Arizona sheriff said investigators

Nancy Guthrie, mother of "Today" show host Savannah Guthrie, has been missing since February 1. Here's what we know about the case.

The sunny "Today" show anchor Savannah Guthrie was struck by grief at 16 after her father's death. America is searching now for her missing mom Nancy.

Investigators have no proof that the missing mother of "Today" show host Savannah Guthrie is still alive but are holding out hope she is "still out there," the sheriff said.

Authorities are still working to identify a potential suspect as they look into alleged ransom notes that have been sent to media outlets.

Savannah Guthrie made a heart-wrenching plea for “proof of life” of her 84-year-old mother. And in this digital age, the NBC “Today” co-anchor says she knows that voices and images can be manipulated.

Savannah Guthrie's brother, Camron Guthrie, issued a plea Thursday for the return of their mother, Nancy Guthrie, saying in a video to the possible abductor, "We want to talk to you."

Nancy Guthrie, 84, was taken from her home against her will in a “possible kidnapping or abduction,” police said.

"We have nobody of interest, or anybody you would consider a prime suspect," Pima County Sheriff Chris Nanos told reporters. "We are just not there yet."
