For years Mark Lanterman has been a go-to expert on tech-based crimes and scams, both on local news and in courtrooms. Now people are asking, was Minnesota's king of digital forensics sitting on a throne of lies?

In an exclusive interview, I spoke with Wisconsin-based lawyer Sean Harrington, who's turned up a trove of evidence calling into question Lanterman's credentials and affiliations. To list just a few of Harrington's discoveries:

-"Lanterman didn’t complete postgrad studies at Harvard University. Rather, he attended an 8-week 'Online short course' administered through GetSmarter® in 2018."

-Lanterman claimed to “serve on the Sedona Conference’s Steering Committee on Artificial Intelligence and the Law" before that particular committee even existed. And the executive director confirmed Lanterman currently holds no leadership position.

-Lanterman's biographies and sworn statements claim affiliation with the US Secret Service for periods ranging from 3, 5, 8, 11, and 29 years.

Perhaps most damning of all: Lanterman's sudden interest in his old personnel file from the 1990s. After being challenged about his credentials in a deposition on February 11, Lanterman traveled to a suburban Philadelphia police station on February 14, told the police chief he had a terminal heart condition and needed to view his old employee file. He took the file home and never sent it back, much to the consternation of the police chief. What was in that file?

There's more in Harrington's thoroughly documented write-up on his website:
