In the ongoing investigation into Nancy Guthrie’s disappearance, authorities have shifted their focus to a distinct pinky ring that her suspected kidnapper was seen wearing in doorbell camera footage recorded shortly before she disappeared.

Pima County Sheriff Chris Nanos revealed on Tuesday that the unidentified man, captured on video at her Tucson, Arizona home, appeared to have a ring on his finger beneath his black gloves.

“When I look at the same image you do, I notice it,” Nanos mentioned to NBC News, referencing the enigmatic figure shown in the footage. “I’ll pass this information on to my team. They’ll examine it thoroughly, and we’ll determine if it’s significant.”

In a related development, TMZ reported on Wednesday that a new, more “sophisticated” ransom note has emerged concerning the disappearance of 84-year-old Nancy, who is the mother of Today host Savannah Guthrie.

“We have received another ransom demand—this one is sophisticated and places the media at its center,” TMZ shared in an Instagram post.

‘We have received yet another ransom demand—this one is sophisticated and puts the media right in the middle of it,’ TMZ wrote in an Instagram post. 

The latest letter demands another large amount of money, but in another cryptocurrency form other than the previously requested $6 million in bitcoin, per the outlet. 

The email also ‘graphically describes the consequences if the ransom isn’t paid,’ the report stated.

The message also included a crypto account number that is different from the one that was originally sent. 

The outlet also revealed that the FBI has contacted law enforcement in Mexico, though the expansion of the investigation has not yielded any new leads. 

The latest update in the mysterious investigation comes after a similar glove found two miles from Nancy’s home failed to match DNA found inside of her property, officials said. 

Nanos said the glove offered no new leads after failing to match the Combined DNA Index System (CODIS) – a national archive of all DNA from arrestees nationwide.

The singular glove was discovered on Sunday and became a briefly regarded piece of evidence in the ongoing case, which has been going on for three weeks now.   

Several leads and pieces of evidence have popped up along the way, but none of them have stuck. 

Persons of interest were previously taken in for questioning, but later released. A number of ransom notes, including several sent to TMZ, have also been revealed.

Nancy was last seen on the night of January 31 after going to her eldest daughter’s house for dinner and a game night. 

Her daughter Annie’s husband, Tommaso Cioni, then drove her back home, just a few miles away. 

Cioni told police he watched his mother-in-law enter her garage door that night. 

Hours later, around 2.12am, Nancy’s Nest doorbell camera detected a person on camera. 

Then, around 2.30am, Nancy’s Apple Watch and iPhone stopped syncing with her pacemaker. 

When 11am rolled around, her local church friends grew worried after Nancy failed to show up for services.

They then notified her family, leading her relatives to check on her home. After not locating her, the family dialed 911 and reported her missing. She has not been seen or heard from since.

Her heartbroken children have taken to social media multiple times, pleading for their mother’s safe return home. 

On Sunday night, Savannah shared a somber video to Instagram, begging her mother’s captors to ‘do the right thing.’ 

‘And I wanted to say to whoever has her or knows where she is that it’s never too late, and you’re not lost or alone, and it is never too late to do the right thing,’ the Today Show host said. 

‘We are here and we believe, and we believe in the essential goodness of every human being, and it’s never too late,’ she concluded the video, which she captioned ‘bring her home.’
