FBI investigating Minnesota cybersecurity expert over concerns about his background, Hennepin Co. att'y says
Mark Lanterman, the Chief Technology Officer at Computer Forensic Services, is being accused by Wisconsin attorney Sean Harrington of inflating his resume and misrepresenting his credentials. Lanterman has accused Harrington of a "smear campaign", but the claims were enough to lead both the Hennepin County Attorney's Office and FBI to probe Lanterman's education and work experiences.
Harrington declined WCCO's request for an interview, but provided a write-up of what he said is his research into Lanterman and several other "frauds." Harrington also said that while his work does include law related to cyber crimes, he rejects the notion that he is one of Lanterman's competitors.
Lanterman, who also has not spoken publicly since the Hennepin County Attorney's Office disclosed the investigation on Wednesday, has said in the past he has worked on more than 2,000 state and federal cases requiring his services.
The attorney's office on Wednesday said it has been unable to verify Mark Lanterman's educational and employment background fully after "concerns were raised."
Lanterman has been a featured speaker at myriad engagements, including a 2017 talk at the University of Minnesota entitled "
Cyber Crime: From Phishing to the Dark Net.
"
Speaking generally about cyber crimes, however, is not the same as testifying as an expert witness, where the individual's credentials are critical to the reliability and credibility of that testimony.
"It's scholarly writings, it's taking seminars, continuing education, and having work experience where you've been able to get into your field of study," Kevin Sieben, a criminal defense attorney in Eagan said. "If there's a case with an expert that's found out to have actually been an expert, that everybody who had that expert in their case should go back and evaluate their case to determine if they can say whether his determination is accurate."
Neither the attorney's office nor the FBI has said which part, or parts, of Lanterman's experience is under review; Harrington's claims about Lanterman cover everything from his education at Harvard University to the length and breadth of his job responsibilities and membership in certain organizations.
Matthew Cybert, the Special Agent in Charge at the U.S. Secret Service Minneapolis Field Office, said on Friday that Lanterman did work with his agency.
"The U.S. Secret Service can confirm that Mr. Lanterman did work on our electronic crimes task force while assigned to the Hopkins Police Department," Cybert said.
A spokesman for the University of St. Thomas likewise confirmed that Lanterman "is currently an adjunct faculty member at the School of Law."
Lanterman says he is also a faculty member at Hamline University in St. Paul. WCCO reached out to the school for comment but has not yet heard back.
While the probes continue, there are already ripple effects in ongoing cases involving Lanternman across the country, including in federal district courts in Florida and New Jersey. In one such case,
Vision Industries Group, Inc. v. ACU Plasmold, Inc.,
Lanterman must appear at a virtual hearing on April 3 to answer questions about his credentials.
A spokesperson for the Hennepin County Attorney's Office has also confirmed, "we have now sent disclosures on ten pending cases we have identified as being potentially impacted."
According to Sieben, when it comes to past cases, there is a much higher bar for overturning judgments or convictions, even if the claims about Lanterman's background turn out to be accurate.
"It's a high standard that we have in the law, and you have to be able to show there was something wrong or faulty about that testimony in addition to them being maybe not a credible witness," Sieben said.
Lanterman, who owns the Minneapolis-based company Computer Forensic Services, says he has testified in over 2,000 cases and is a former member of the U.S. Secret Service Electronic Crimes Task Force, according to a biography on his company's website, which has since been removed.

Raskin: Maxwell prison move ‘speaks to the irregularity of the process'
Rep. Jamie Raskin (D-Md.) on Wednesday questioned disgraced socialite Ghislaine Maxwell's recent prison transfer, as lawmakers press the Trump administration to release more files related to its probe of the late Jeffrey Epstein's sex trafficking case. Maxwell, who was convicted and sentenced to 20 years as Epstein's co-conspirator, was quietly transferred from a Florida prison to a lower-security prison camp in Texas earlier this month, according to the Federal Bureau of Prisons (BOP). The move comes as she is appealing her case to the administration and Supreme Court. 'It was practically instantaneous. And of course, that then speaks to the irregularity of the process leading up to it,' Raskin said during a Wednesday appearance on MSNBC's 'The Last Word.' 'Remember that this was preceded by the sacking of Maureen Comey, who was one of the senior prosecutors leading that prosecution, and they simply fired her,' he continued. 'And then that's when [Deputy Attorney General] Todd Blanche decided to take matters into his own hands.' Blanche, who formerly defended President Trump during criminal proceedings, met with Maxwell one-on-one in Florida for two days to discuss Epstein. The case resurfaced after the Justice Department (DOJ) and FBI released a joint memo last month finding the disgraced financier did not keep a 'client list.' It also sought to dispel conspiracies around his 2019 death in a New York City jail cell, which has been ruled a suicide. Raskin suggested Blanche helped move Maxwell because he liked what he heard in the closed door meetings. 'So look, I think it seems pretty clear to the vast majority of Americans, as you're pointing out this evening, that Donald Trump's got one major interest in this whole affair at this point, which is burying any information that reveals the connection between him and Jeffrey Epstein,' the Maryland Democrat said. 'We know that they had more than a thousand FBI agents working 24 hour shifts, looking for mentions of Donald Trump's name in the Epstein files and looking for photographs of him, video snippets of him, whatever it might be,' he added. President Trump, following pressure from his base, ordered the DOJ to make transcripts of the five days of Epstein and Maxwell's grand jury testimonies public and to ask the court to unseal exhibits related to the case. A judge days later denied the request. While Republican lawmakers left Washington earlier this summer to avoid the controversy, it is likely to ramp up once again when they return in September.

Providence's Bonded Vault robbery, 50 years later
I asked Tim to reflect on everything he's learned, and update us on whether we'll ever see a proper version of this story told on the big screen. Q: You're airing a special report at 5 p.m. and 6 p.m. on the 50th anniversary of the heist. What should viewers expect to see? Advertisement White: I've tracked down a lot of material over two decades of reporting on the heist, including a wild video of the lead gunman's alleged funeral. A while ago, someone leaked me another video of him discussing the caper – he was in witness protection at the time, so it was kept under wraps for years. Tonight's reports use WPRI archive video to retell how the heist went down, showcase its impact on Get Rhode Island News Alerts Sign up to get breaking news and interesting stories from Rhode Island in your inbox each weekday. Enter Email Sign Up Q: This story has had a decades-long shelf life, and you coauthored the definitive book on it. But I still wonder if readers today understand quite how seismic it was in the 1970s. Is this even the kind of heist that could happen today? Advertisement White: This heist shouldn't have happened then, to be honest – the gang of thieves that stormed 101 Cranston St. in Providence wasn't exactly the crew from 'Ocean's 11.' And what made it even more remarkable was that Bonded Vault was probably the safest place to hide ill-gotten gains in 1975, because it was controlled by the mob itself. But as we detailed in the book, the gang had the approval of the boss himself, the late Raymond L.S. Patriarca, though he always denied involvement. The case wound up leading to the longest and most expensive trial in state history, and had all sorts of other ripple effects. Q: Your father was obviously a legendary reporter, and you have a great story about how your family helped you land the scoop of a lifetime when you tracked down one of the leaders of the robbery. Tell us about that. White: My coauthors and I were struggling to figure out what happened to the lead gunman, Robert Dussault. The feds whisked him away after he testified for the government. In 2008, three years after Dad died, my mom brought me a box of stuff from her basement which included an empty envelope. The return address was from Colorado with a name I didn't recognize: Robert Dempsey. But I remembered Dad telling me Dussault was relocated and given a job at Coors Brewing. I figured out the return address was a prison, and records showed the inmate was dead. I used those documents to request Dempsey's FBI file, and nearly two years later I got a box in the mail with hundreds of pages. The top sheet: 'Robert Dussault a.k.a. Robert Dempsey.' It completed the story. If mom hadn't dropped off that box, I'm not sure we'd be doing this Q&A. Advertisement Q: You wrote the book about this, and there was also a third-rate White: Bestselling author and screenwriter Don Winslow is still very interested in the project, and as far as Wayne, Randy and I are concerned, he has the best vision for it. Keep your fingers crossed for us. Q: I have to finish with the obligatory organized crime question. We know the Mafia isn't remotely as powerful as it was in the 1970s. But do underground safes or banks like the one in this story still exist for mobsters to hide their ill-gotten gains? White: If there's anything like Bonded Vault that exists today, I'm not aware of it. In this era, tangible loot is more likely to be smuggled to a foreign country with looser rules. And contemporary organized crime cases show 'underground safes' are more often computer network servers that store scammed funds. Call me old school, but it's just not as interesting as a secret room tucked away inside a Providence fur storage warehouse.

FBI returns stolen 500-year-old document signed by Spanish conquistador to Mexico
Federal authorities say they've returned a lost page from a 500-year-old manuscript to Mexico, decades after portions of it went missing. Dating back to the 16th century, the document describes an early payment structure established by the Spanish military commander who conquered parts of modern-day Latin America, according to the FBI. "This is an original manuscript page that was actually signed by Hernán Cortés on February 20, 1527," said FBI special agent Jessica Dittmer, a member of the bureau's art crime team, in a statement. The page "outlines the payment of pesos of common gold for expenses in preparation for discovery of the spice lands, so it really gives a lot of flavor as to the planning and preparation for unchartered territory back then," Dittmer said. Cortés was a conquistador known for his takeover of the Aztec empire, which ruled over what is now Mexico, during the early 1500s. He claimed the region for his native Spain, in a conquest that historians say laid the foundation for an ensuing colonial territory called "New Spain," encompassing vast sections of contemporary Mexico, Central America and the United States, in addition to places in the Caribbean and the Pacific. According to Dittmer, the manuscript that Cortés signed holds historical significance because it includes a detailed account of the conqueror's journey from Europe to the Americas. "Pieces like this are considered protected cultural property and represent valuable moments in Mexico's history, so this is something that the Mexicans have in their archives for the purpose of understanding history better," the agent said. The manuscript was initially repatriated to Mexico and held at the country's national archives, where archivists in 1993 discovered that 15 pages of it had disappeared, the FBI said. Decades later, in 2024, the Mexican government requested assistance from the bureau's art crime team in recovering one specific page from the lost group. Working with authorities in Atlanta and New York, federal investigators eventually found and seized the missing page, from a location within the U.S. that they haven't disclosed. The FBI said that the page was likely stolen from Mexico's national archives at some point between 1985 and 1993, based on the filing system that archivists used in that time frame. Federal officials returned the document to Mexico on Wednesday. Authorities will not prosecute anyone in connection with the theft because investigators determined that the documents "changed hands several times over" since it went missing, the FBI said. "We know how important it is for the United States to stay ahead of this, to support our foreign partners, and to try and make an impact as it relates to the trafficking of these artistic works and antiquities," said Veh Bezdikian, a supervisory special FBI agent, in a statement.
