Federal investigators have now obtained long-awaited footage tied to the disappearance of Nancy Guthrie, the 84-year-old mother of Today host Savannah Guthrie, as the frantic search drags into its second month.

Sources say the FBI has reviewed video from an Uber ride Nancy took the night before she vanished — a trip from her Tucson, Arizona, home to her daughter Annie’s house on January 31.

According to Crime Stories with Nancy Grace, the footage came from inside the vehicle and has been turned over to federal agents. Police had previously reviewed the clip and reportedly found “nothing of substance” connected to the disappearance. The Uber driver was interviewed as well, and investigators said nothing seemed out of the ordinary.

The video has not been released publicly.

Nancy was last seen at her home the night of January 31. Investigators say she was abducted from her Tucson residence on February 1, after blood and signs of forced entry were discovered inside the home.

After the Uber drop-off, authorities say Nancy later returned home with help from her son-in-law, Tommaso Cioni.

The FBI’s Phoenix field office declined to comment when contacted.

Meanwhile, the case has been fueled by unsettling images and mounting public pressure. Early in the investigation, authorities released doorbell camera video showing a masked figure in the early morning hours on the day Nancy was reported missing. Weeks later, another image surfaced showing a suspicious person at the home the day before the suspected abduction, sources familiar with the investigation told ABC News.

The reward money has also skyrocketed.

Nancy’s family is offering $1 million for information leading to her being found. The FBI is separately offering up to $100,000 for information that leads to her recovery and/or the arrest and conviction of anyone involved.

But despite the massive attention, the investigation has appeared to stall in recent weeks — and the case has taken a chaotic turn with ransom claims. Multiple outlets reportedly received letters demanding Bitcoin from people claiming to be the kidnappers. One person who contacted the family seeking Bitcoin was arrested last month.

Pima County Sheriff Chris Nanos has faced criticism over the handling of the case and is now staring down a recall effort. He also told The New York Times the search could take years — a grim possibility that has only intensified outrage and fear.

NBC previously said Savannah “plans to return” to the network, but she’s continued speaking directly to the person who took her mother in emotional public messages.

“I wanted to say to whoever has her or knows where she is, that it’s never too late,” Savannah said in a video posted February 15. “You’re not lost or alone and it is never too late to do the right thing, and we are here. We believe in the essential goodness of every human being and it’s never too late.”

For now, the newest development is this: the FBI has the Uber footage — and even if it doesn’t show a smoking gun, it’s another piece in a case that refuses to go quiet.
