New surveillance video of a masked and apparently armed person on Nancy Guthrie’s doorstep the night she went missing was released Tuesday by federal investigators.
It’s the first major break in the intensifying search for the 84-year-old mother of “Today” show host Savannah Guthrie. Authorities are seeking help identifying the person in the video.
No suspects or persons of interest have been identified, but authorities detained someone south of Tucson on Tuesday for questioning in the case.
It’s been more than a week since investigators believe Nancy Guthrie was abducted from her home in Arizona.
Her children have made heartbreaking video pleas for help and the case has drawn national attention. Two deadlines in purported ransom notes sent to the media have come and gone, but it’s unclear of there’s been any contact with the abductors or if Nancy Guthrie is still alive.
Here is a timeline of events:
Saturday, Jan. 31
5:32 p.m. — Nancy Guthrie takes an Uber to her family’s home for dinner.
9:48 p.m. — Guthrie is dropped off at her Tucson, Arizona, home by a family member. The garage door opens and closes minutes later.
