On Wednesday, FBI personnel meticulously combed through the rugged terrain surrounding Nancy Guthrie’s $1 million residence, as the search for her entered its 11th day.

Guided by a woman in a blue shirt and green pants from the evidence collection unit, the team explored the area for nearly an hour. They navigated through large cacti, looking for any signs that might illuminate the mystery of the disappearance of TV personality Savannah Guthrie’s 84-year-old mother.

During their search, agents would occasionally stop to examine potential clues before continuing their thorough investigation of the land flanking the road near the grandmother’s Catalina Hills home in Tucson, Arizona.

Their diligence paid off when they discovered a black glove, resembling one seen on the abductor in the eerie doorbell camera footage captured on the night Nancy was taken.

The glove, found nestled in a small shrub, was carefully collected by authorities. While they have yet to reveal the glove’s potential owner, they maintain a cautious silence on the matter.

This finding follows the federal release of alarming video footage, which showed a masked individual in thick gloves attempting to block the camera on Nancy’s front porch.

Meanwhile, Barb Dutrow, who was jogging through a neighborhood where teams were searching on Wednesday, told the Associated Press that an FBI agent told her they were looking for anything that might have been tossed from a car.

At the same time, investigators were also spotted combing through the mail at daughter Annie’s mailbox.

It marked the fourth time the FBI has visited Annie’s house since her mother’s disappearance in the early morning hours of February 1, though the first two visits were conducted simply to update the family on the search efforts and to film a video responding to reported ransom notes.

Annie and her husband, Tommaso Cioni, were the last people to see Nancy, who visited their home for dinner on January 31.

She was then reported missing the next day after she failed to show up to a friend’s house to watch virtual church services. 

Nancy has not been seen or heard from since.

The investigation into her disappearance has since apparently come to a standstill after a person of interest who was taken into custody for questioning was released without any criminal charges. 

Making matters even more tense for the Guthrie family, FBI Director Kash Patel  told Fox News on Tuesday that the bureau is actively looking at several individuals without providing any further detail. 

He said: ‘I will say we have made substantial progress in these last 36 to 48 hours, thanks to the technical capabilities of the FBI and our partnerships.

‘I do believe we are looking at people who, as we say, are persons of interest. With any investigation, you’re a person of interest until you’re either eliminated or you’re actually found to be the culprit or the culprits involved, and that’s the stage we’re at right now.’

But TMZ later reported that it received a new ransom note, claiming it stated that the sender has tried unsuccessfully to get in contact with Camron Guthrie, Nancy’s son, and Annie.

In the message, the sender reportedly said they had information on the identity of the suspect who was seen at Nancy’s $1 million Tucson home the night she vanished.

‘If they want the name of the individual involved then I want 1 Bitcoin to the following wallet. Time is more than relevant,’ the note allegedly read.

The Bitcoin address listed in the note is reportedly legitimate and different from the one in an original ransom note that TMZ and two local news stations in Arizona also received.

TMZ host Harvey Levin appeared on Fox News Channel’s America’s Newsroom earlier on Wednesday to confirm the outlet had received the third letter.

‘An hour and a half ago, we got, kind of a bizarre letter, an email from somebody who says they know who the kidnapper is and that they have tried reaching Savannah’s sister Annie and Savannah’s brother, to no avail,’ he said.

‘And they said they want one Bitcoin sent to a Bitcoin address that we have confirmed is active.

‘It’s a real Bitcoin address, and as they put it, time is more than relevant. So we have no idea whether this is real or not. But they are making a demand,’ he added.

Yet several law enforcement experts have expressed their concern that the latest Bitcoin demand sent to TMZ might be a scam.

Former FBI assistant director Chris Swecker told Fox News on Wednesday that he is ‘highly skeptical’ of the note.

‘I just don’t think anything TMZ has brought forward has panned out. I mean it’s a good vehicle for people to come in and do this, TMZ gets some viewership and it sort of ties up the investigative team trying to run this down. But I sense a scam here,’ Swecker said.

‘I may be absolutely wrong, I hope I am, I love to think that this is a viable lead but I think it’s one of many hundreds that are coming in through the proper channels, which is the FBI tip line. Bottom line is I’m very skeptical of it’

Former NYPD Inspector Paul Mauro also told Fox News that, ‘You’d have to ask yourself what the motivations are here.’

He said, ‘We’re all still trying to process this latest thing that came in from TMZ and look, when you consider the atmospherics around this thing, we’ve had a couple of other emails that didn’t pan out that very well might have been hoaxes, unscrupulous people trying to pile into this thing.

‘You have to say to yourself with this latest one asking for a Bitcoin worth about $66,000 when the reward is $50,000, and you could come forward and be a hero. You’d have to ask yourself what the motivations are here.’

Mauro added, ‘Looks to me like [it] could be a hoax. Certainly, you have to admit that possibility, but it could be genuine. They gave reportedly an email address to facilitate communication, you can bet that the authorities are scraping very hard at that.

‘Either way, it’s somebody that should have just come forward if they have genuine information. So right now, this is a pertinent investigative lead. But I’m not sure it’s the most important one.’

After nearly an hour, the FBI team left in a black Toyota SUV

In the meantime, the Pima County Sheriff’s Department said it is combing through thousands of tips with ‘several hundred detectives and agents’ assigned to the case. 

The FBI also said on Wednesday that ’numerous FBI agents are conducting an extensive search along multiple roadways in the Catalina Foothills area related to the Nancy Guthrie investigation.’

At one point during the search, a woman came up to the female agent saying she had something of interest and the pair huddled in the road to have a quiet conversation.

However, the team did not immediately follow up the unknown tip and the woman left quickly while the agents carried on their quest, dodging sharp vegetation in the rocky terrain.

Asked how the search was going, the female agent refused to answer and the team eventually left in a black Toyota SUV.
