An officer operated the fictitious account. Investigators also used phone-number searches, facial recognition and vehicle tracking in the same case.

The operation paired a synthetic profile image with an undercover officer’s conversations: an AI-generated picture drew contact on Taimi, while FBI Task Force Officer McKailey Scott supplied the age of 15 and the messages that allegedly established sexual interest. Investigators used phone-number and facial-image searches to identify Christopher Thomas Mertens, then tracked his car to the planned meeting, where Livonia police arrested him. The account is based on an affidavit and 404 Media’s reporting; the complaint does not identify the Illinois high school where Mertens said he worked.
Scott created the Caleb account without an age; after the user asked, Scott said Caleb was 15.
Over several days, Mertens allegedly sent sexually explicit messages and arranged a meeting, believing Caleb’s parents would be away.
Investigators used Thomson Reuters CLEAR for the phone number, Clearview AI for facial-image searches, and Flock to track the car.
The teenager Christopher Thomas Mertens allegedly arranged to meet did not exist. An undercover officer had used an AI-generated image to create the persona of a boy presented as 15. Livonia police arrested Mertens when he arrived at the meeting spot, according to an October 16 report by 404 Media, produced with Court Watch.
The account of the operation comes from an affidavit by FBI Task Force Officer McKailey Scott. It describes an investigation by Livonia’s Undercover Resistance to Exploitation Unit, known as LURE, which investigates child sex offenders. The alleged contact began in September.
Scott created an account named Caleb on Taimi, a queer-focused dating app. The profile used an AI-generated picture of a teenage-appearing male but listed no age. According to the affidavit, an initially unidentified user contacted the account, and the conversation moved to WhatsApp.
A few minutes into their exchange, the user asked Caleb’s age. Scott, posing as Caleb, answered that he was 15. The affidavit says the user then expressed sexual interest. Investigators subsequently identified that user as Mertens.
Over several days, Mertens allegedly exchanged sexually explicit messages with the undercover account and arranged to meet Caleb on his day off. He believed the boy’s parents would not be home. Both the teenager and that household scenario were fictitious.
The image generator was not the only technology involved. Investigators used two identification tools: Thomson Reuters CLEAR to check the user’s phone number, and Clearview AI to search images of his face. Those searches helped identify him as Mertens, according to 404 Media’s account.
Police then used Flock to look up and track his car as he drove toward the planned meeting. They also had updates from the conversation itself: Mertens allegedly continued texting Caleb during the journey, saying he was on his way and later that he had arrived.
Officers took Mertens into custody when he got out of the car. About two hours after booking, he asked jail attendants to speak with Scott. According to the account, Mertens then admitted the conduct and said he worked at a high school in Illinois. The complaint did not identify the school.
Livonia police did not respond to 404 Media’s request for comment.
