What they're saying:

"Someone needs to do the right thing. We are in agony. We are in agony," a tearful Savannah Guthrie told Hoda Kotb in a preview of the interview that will air in full later this week.

Nancy Guthrie: Family seeks 'renewed attention' to case in new message

The family of Nancy Guthrie, mother of Today show host Savannah Guthrie, has issued a plea for new information and home surveillance footage, focusing on three key dates—January 11, January 31, and February 1.

Savannah Guthrie has been away from the "Today" show since her mother's disappearance on Feb. 1. She returned to the "Today" show studio on March 5 where she was seen visiting her colleagues.

"It is unbearable, and to think of what she went through. I wake up every night, in the middle of the night, every night, and in the darkness, I imagine her terror, and it is unthinkable, but those thoughts demand to be thought, and I will not hide my face, but she needs to come home now," Savannah told Kotb.

Savannah's full interview will air in two parts on the "Today" show on Thursday and Friday.

The backstory:

Nancy Guthrie, 84, went missing on the night of Jan. 31 and was reported missing on Feb. 1 when she didn't show up for church. Authorities believe Nancy was taken from her home against her will.

Since her disappearance, the FBI has released footage of her alleged abductor at her doorstep.

The sheriff's department asked for anyone within a 2-mile radius of Guthrie's Catalina Foothills home to submit any footage they may have from Jan. 1 to Feb. 2 that they "deem out of the ordinary or important."

What you can do:

Savannah says her family is offering a $1 million reward for the recovery of Nancy. Anyone with information should contact the FBI at 1-800-CALL-FBI.

The Pima County Sheriff's Department has also set up a tipline where the community can submit information. An online form is available for tips.
