The search for Nancy Guthrie continues after she disappeared from her home in Tucson, Ariz. two weekends ago, and imposter kidnappers have swarmed.

Law enforcement has said they’ve received several ransom notes from people claiming to have the mother of Today show co-host Savannah Guthrie. Savannah and her siblings, Annie and Camron, have been posting videos to social media pleading for Nancy Guthrie, 84, to be returned home, and have asked for proof of life before any ransom is paid.

“We are ready to talk. However, we live in a world where voices and images are easily manipulated,” Savannah Guthrie said in one video and asking for proof that her mother was still alive.

As artificial intelligence becomes more advanced and commonplace, it can be difficult to know what’s real and what’s not, which has complicated the search for Nancy Guthrie, according to law enforcement. But just how difficult is it?

AI can ‘make up just about anything’

Before the days of artificial intelligence, proof of life could be easily established by having a hostage take a picture holding a newspaper of the day, or talking on the phone, said Joseph Lestrange, who worked in law enforcement for 32 years and now trains law enforcement agencies on identifying artificially generated content.

Now, someone can ask a language learning model to mimic someone’s voice or likeness in photos, videos and audio, known as “deepfakes.” The models can also devise fake documents, like passports, Lestrange said.

“You give it the right prompts, it can pretty much make up just about anything,” Lestrange said.

At federal agencies, digital evidence is usually sent to digital forensics labs. Examiners there can judge the authenticity of a piece of evidence using clues such as its location data or pixels. The tools they use are “very effective,” Lestrange said, but it takes time for them to draw conclusions.

“Time is usually of the essence in these kidnapping cases, especially in the current case we’re talking about, where the poor woman has some health problems,” he said. “So these investigators are really in a challenging situation at this point.”

Local and state agencies also may not have access to the same kind of tools, while scams are becoming more complex, and fast, Lestrange said.

Lestrange said some agencies are more willing than others to embrace how artificial intelligence is used. This can start to be corrected if emerging AI companies collaborate with law enforcement to “develop products that make sense,” so law enforcement isn’t “just relying on the vendors to tell them what they need,” he said.

How to protect yourself from AI scams and deepfakes

Although artificially generated content and deepfakes rely on digital tools, human interference and judgement is still a good way to tell if something is off, said Eman El-Sheikh, the associate vice president of the University of West Florida Center for Cybersecurity.

“First, calm down and slow down, because a lot of times scammers will try to create a fake sense of urgency in order to get their way before the other people can figure out that this is a fake,” she said.

While on the call, you can say something that you know your loved one is likely to respond to in a certain way. Or you can hang up and call your loved one directly to verify the issue, El-Sheikh said.

People who use social media should avoid publishing sensitive information, such as passwords, addresses and phone numbers, she said. It’s also important to keep details regarding your home private, such as when you’re leaving the house, or that you live alone.

Also, make sure to review the privacy settings on your apps, and toggle the permissions according to your comfort level, she said.

“It’s very important for everybody in the digital world to be very intentional about what information they say online, and about protecting their privacy.”

But Lestrange notes that anything you post or share about yourself online can be used against you, even if you’re careful.

“It’s really a very different world today,” he said.

Map: 4.9-Magnitude Earthquake Shakes Louisiana

Note: Map shows the area with a shake intensity of 4 or greater, which U.S.G.S. defines as “light,” though the earthquake may be felt outside the areas shown.  All times on the map are Central time. The New York Times

A light, 4.9-magnitude earthquake struck in Louisiana on Thursday, according to the United States Geological Survey.

The temblor happened at 5:30 a.m. Central time about 6 miles west of Edgefield, La., data from the agency shows.

U.S.G.S. data earlier reported that the magnitude was 4.4.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

Man accused of plot to assassinate Trump testifies Iran pressured him, says Biden and Haley were other possible targets

Man accused of plot to assassinate Trump testifies Iran pressured him, says Biden and Haley were other possible targets

The allegation sounded like the stuff of spy movies: A Pakistani businessman trying to hire hit men, even handing them $5,000 in cash, to kill a U.S. politician on behalf of Iran ‘s powerful paramilitary Revolutionary Guard.

It was true, and potential targets of the 2024 scheme included now-President Donald Trump, then-President Joe Biden and former presidential candidate and ex-U.N. Ambassador Nikki Haley, the man told jurors at his attempted terrorism trial in New York on Wednesday. But he insisted his actions were driven by fear for loved ones in Iran, and he figured he’d be apprehended before anything came of the scheme.

“My family was under threat, and I had to do this,” the defendant, Asif Merchant, testified through an Urdu interpreter. “I was not wanting to do this so willingly.”

Merchant said he had anticipated getting arrested before anyone was killed, intended to cooperate with the U.S. government and had hoped that would help him get a green card.

U.S. authorities were, indeed, on to him – the supposed hit men he paid were actually undercover FBI agents – and he was arrested on July 12, 2024, a day before an unrelated attempt on Trump’s life in Butler, Pennsylvania.  During a search, investigators said they found a handwritten note that contained the codewords for the various aspects of the plot, CBS News previously reported

Merchant did sit for voluntary FBI interviews, but he ultimately ended up with a trial, not a cooperation deal.

“You traveled to the United States for the purpose of hiring Mafia members to kill a politician, correct?” Assistant U.S. Attorney Nina Gupta asked during her turn questioning Merchant Wednesday in a Brooklyn federal court.

“That’s right,” Merchant replied, his demeanor as matter-of-fact as his testimony was unusual.

The trial is unfolding amid the less than week-old Iran war, which killed Iranian Supreme Leader Ayatollah Ali Khamenei in a strike that Trump summed up as “I got him before he got me.” Jurors are instructed to ignore news pertaining to the case.

The Iranian government has denied plotting to kill Trump or other U.S. officials.

Merchant, 47, had a roughly 20-year banking career in Pakistan before getting involved in an array of businesses: clothing, car sales, banana exports, insulation imports. He openly has two families, one in Pakistan and the other in Iran – where, he said, he was introduced around the end of 2022 to a Revolutionary Guard intelligence operative. They initially spoke about getting involved in a hawala, an informal money transfer system, Merchant said.

Merchant testified that his periodic visits to the U.S. for his garment business piqued the interest of his Revolutionary Guard contact, who trained him on countersurveillance techniques.

The U.S. deems the Revolutionary Guard a “foreign terrorist organization.” Formally called the Islamic Revolutionary Guard Corps, the force has been prominent in Iran under Khamenei.

Merchant said the handler told him to seek U.S. residents interested in working for Iran. Then came another assignment: Look for a criminal to arrange protests, steal things, do some money laundering, “and maybe have somebody murdered,” Merchant recalled.

“He did not tell me exactly who it is, but he told me – he named three people: Donald Trump, Joe Biden and Nikki Haley,” he added.

In 2024, multiple sources familiar with the investigation told CBS News Merchant planned to assassinate current and former government officials across the political spectrum.

Merchant allegedly sketched out the plot on a napkin inside his New York hotel room, prosecutors said, and told the individual “that there would be ‘security all around’ the person” they were planning to kill.

“No other option”

After U.S. immigration agents pulled Merchant aside at the Houston airport in April 2024, searched his possessions and asked about his travels to Iran, he concluded that he was under surveillance. But still he researched Trump rally locations, sketched out a plot for a shooting at a political rally, lined up the supposed hit men and scrambled together $5,000 from a cousin to pay them a “token of appreciation.”

He even reported back to his Revolutionary Guard contact, sending observations – fake, Merchant said – tucked into a book that he shipped to Iran through a series of intermediaries.

Merchant said he “had no other option” than to play along because the handler had indicated that he knew who Merchant’s Iranian relatives were and where they lived.

In a court filing this week, prosecutors noted that Merchant didn’t seek out law enforcement to help with his purported predicament before he was arrested. He testified that he couldn’t turn to authorities because his handler had people watching him.

Prosecutors also said that in his FBI interviews, Merchant “neglected to mention any facts that could have supported” an argument that he acted under duress.

Merchant told jurors Wednesday that he didn’t think agents would believe his story, because their questions suggested “they think that I’m some type of super-spy.”

“And are you a super-spy?” defense lawyer Avraham Moskowitz asked.

“No,” Merchant said. “Absolutely not.”
