AI system as recorded: Generative AI image-alteration software (unidentified) that police say was used to alter recordings of students into explicit images

What Happened

Illinois authorities charged a middle-school teacher over allegations that he recorded students and used AI to make sexual images of them. Officials described a forensic examination and support for affected students. He was detained pending proceedings.

Reported harm

Photos and videos of middle-school students were allegedly altered with AI into explicit images by their teacher (police and State's Attorney statements via the Lake & McHenry County Scanner, ABC7, Patch, the Daily Herald, CBS Chicago and the Chicago Tribune); the district says supporting students' well-being is its immediate focus and authorities say they are connecting affected families with support services. The allegations are charges awaiting trial.

Outcome

Ongoing

Illinois authorities charged a middle-school teacher over allegations that he recorded students and used AI to make sexual images of them. Officials described a forensic examination and support for affected students. He was detained pending proceedings.

What remains unknown

  • How many students appear in the altered images and whether the material was shared beyond the accused's devices.
  • The outcome of the 30 July 2026 preliminary hearing and the case's current status; any plea or trial date.
  • The software used; authorities describe an AI program placing students' heads on other bodies but do not identify it.
  • When the photos and videos were taken beyond the afternoon of 3 June 2026 described in the district statement; the release refers to videos taken in class without dates.
  • The accused's plea; officials initially gave a different first name, corrected in later copy.

What the evidence supports

AI involvement: reported. The [school/biographical detail withheld] Police and Lake County State's Attorney release says the forensic examination found images of students 'altered using AI to create explicit images' (Scanner wording; ABC7 and Patch paraphrase); the State's Attorney's Office told the Chicago Tribune an AI program was used to place students' heads on other people's bodies, and CBS Chicago reports officials describing generative AI alteration of photos and videos. These are charging statements, not court findings; the software is not identified.

2 claims: 2 reported. What the statuses mean

Reported Illinois police and prosecutors announced eight child-pornography charges against a teacher in July 2026. They allege that forensic examination found students’ photographs altered into sexual images using AI.

Henderson Police said that on 'last Thursday' (17 September 2026) they received a report that AI-generated nude images of children were being created and shown to other students at South Middle School in Henderson, Kentucky. During the investigation officers found and identified AI-generated photographs of two minor victims on a digital device. A juvenile accused of sharing the images was lodged at the Juvenile Detention Center on three charge types: distribution of sexually explicit images without consent; two counts of possession or viewing of matter portraying a sexual performance by a minor over 12 and under 18; and distribution of matter portraying a sexual performance by a minor over 12 and under 18. The school said on Monday 21 September that it was aware of a situation involving a student allegedly misusing artificial intelligence and inappropriate images, that the police investigation was active and that it had remained in communication with the families involved. 14 News (WFIE) reported the case on 21 September; WKYT carried the same report.

Cookeville, Tennessee: two high-school students were charged with aggravated sexual exploitation of a minor after the sheriff's office said they used an AI program to turn photographs, including those of female classmates, into sexually explicit images and posted them; the mother of one depicted girl says her daughter shut herself in her room and stopped talking to friends

On 31 August 2026 the Putnam County Sheriff's Office was told of possible sharing of sexually explicit images at Cookeville High School. Detectives found that two male teenage students had used an artificial-intelligence program to turn photographs obtained online, in some cases photographs of fellow female students, into sexually explicit images, and had shared them; explicit images already stored on one phone were also shared. Both juveniles were taken to the Putnam County Juvenile Detention Center. One was charged with one count each of aggravated sexual exploitation of a minor and especially aggravated sexual exploitation of a minor, the other with two counts of each. The district attorney told NewsChannel 5 on 21 September that the two would be prosecuted in juvenile court. The mother of one of the depicted girls told the station the episode was very hard on her daughter, who had made no naked photographs herself, locked herself in her room and would not talk to her, to anybody or to her friends. The sheriff's-office account and the school system's statement were carried by WZTV, WSMV and 3B Media News on 1-2 September; NewsChannel 5 added its own interviews with the sheriff, the district attorney and the mother on 21 September. The tool is not named. The juveniles are not named in any report.

Gilmer County, Georgia: a vendor who restocked drink machines in local schools used AI applications to turn ordinary photographs of students into child sexual abuse material; prosecutors identified more than 150 underage victims, he was convicted on 118 counts and sentenced on 2 September 2026 to 40 years in prison, and parents of eight students sued Pepsi entities for keeping him on the school route

According to the DeKalb County District Attorney's Office, which prosecuted the case as conflict prosecutor, the investigation began in December 2024 when a Gilmer High School student told a school resource officer that a vendor who refilled drink machines on campus had asked her through a social media app to send him pictures. The Gilmer County Sheriff's Office arrested him in January 2025 and searched his devices, car and home. Prosecutors say he downloaded photographs of minors from social media and used AI applications and bots to alter them so the children appeared nude or engaged in sexual activity, and that the material related to more than 150 underage victims in Georgia and other states, many of them Gilmer County students. A Cobb County senior judge found him guilty on 13 August 2026 of 118 counts of sexual exploitation of children and on 2 September 2026, after 19 victim impact statements, sentenced him to 60 years with 40 to serve in prison. Separately, the parents of eight female students aged 12 to 17 sued him, Pepsi Beverage Co. and Pepsi-Cola Sales and Distribution in a suit reported on 28 February 2025, alleging the companies reinstated him to the same school route after students complained that he was photographing them; USA Herald reported the negligence suit again on 26 September 2026 and said Pepsi had not yet responded publicly. The AI tools are not named and the court and status of the civil suit are not reported.
