Judge lets wrongful-arrest lawsuit proceed over alleged reliance on an AI face match

A Kentucky detective must continue defending a wrongful-arrest lawsuit after a federal judge rejected his bid to end the case on November 9, 2026. Alain Osorio alleges an unverified AI face match led to his arrest. Judge S. Chad Meredith said constitutional protections do not permit an arrest based solely on an uncorroborated AI conclusion.

Meredith also declined to grant Detective Ryan Kilmer qualified immunity, a protection that can shield government officials from personal liability. The decision lets Osorio pursue his claims; it does not establish that Kilmer is liable, and no damages have been awarded.

From bank footage to an arrest warrant

The investigation began with an attempted check fraud at Heritage Bank in Florence, Kentucky, on August 30, 2024. A man presented a Texas driver’s license that a teller suspected was fake. The teller refused to cash the check, and the man left without receiving money. Security cameras captured his face.

According to the allegations, Kilmer took a screenshot from the footage and used facial-recognition technology to compare it with a booking photograph and a Facebook profile image. Osorio says the detective accepted the AI identification without independently confirming that he was the person shown at the bank.

The Facebook profile bore another person’s name. The complaint did not explain why Kilmer concluded that person was Osorio, whose photograph appeared in booking records. Osorio also alleged that his photograph and the bank image differed in head shape, haircut, facial features and complexion.

Kilmer signed a criminal complaint describing the identification as the result of investigative tools and photograph comparisons. Osorio alleges that description concealed exclusive reliance on facial recognition. The complaint was used to obtain an arrest warrant.

Officers arrested Osorio in Florida on January 9, 2025, and he was extradited to Kentucky to face two charges of criminal possession of a forged instrument. He was arraigned on January 23 and released on bond the next day, after more than two weeks in jail.

Prosecutors dismissed the indictment with prejudice on May 7, 2025, after Osorio established that he had been working in Nebraska when the attempted fraud occurred. His lawsuit includes claims of false arrest and malicious prosecution.

A suggested identity is not sufficient grounds for arrest

Florence Police Department policy treats facial recognition as an investigative lead, not a standalone basis for probable cause—the grounds needed to justify an arrest. Further investigation is required. Osorio alleges Kilmer failed to follow that policy.

Meredith’s reasoning focused on the officer’s responsibility to assess probable cause rather than delegate that judgment entirely to AI. He also said there was good reason to believe a warrant would not have been issued had Kilmer fully explained how he identified Osorio.

While AI facial recognition technology has rapidly developed over recent years and is likely more reliable than a Magic 8 Ball, placing unquestioned reliance on such technology is still not much different in principle from placing unquestioned reliance on a Magic 8 Ball.

The immunity dispute remains open

Kilmer denies wrongdoing and argues that Osorio has not shown a violation of clearly established law. Meredith rejected that argument at this stage: an officer could not rely solely on a Magic 8 Ball to obtain a warrant, he reasoned, then claim immunity because no earlier ruling addressed that particular device.

Evidence gathered during discovery could change the outcome, and Kilmer can raise further legal arguments. He was given 14 days to respond to the amended complaint. A court status conference is scheduled for November 19, 2026.
