High reported severity Involving minors Criminal Charges

Libertyville, Illinois: a Highland Middle School social studies teacher was charged on 3 July 2026 with eight counts of child pornography after students reported he was recording them in class and a forensic examination found images of students altered with AI into explicit images; ordered detained on 6 July

A 44-year-old social studies teacher who had worked for Libertyville School District 70 for 18 years was taken into custody on 3 July 2026 on eight counts of child pornography (two Class X and six Class 1 felonies), Libertyville police and the Lake County State's Attorney's Office announced. The investigation began on 3 June 2026, the second-to-last day of the school year, after several students told school leaders that afternoon that the teacher had taken inappropriate photos or videos of them in his classroom; the district says it immediately removed him from the classroom, placed him on administrative leave and contacted the police. A forensic examination of his phone by the State's Attorney's Cyber Lab found numerous images of students that had been altered using artificial intelligence to create explicit images, and search warrants at his home, assisted by electronic-storage-detection dogs, recovered further devices and explicit child images; the State's Attorney's Office told the Chicago Tribune that an AI program was used to place students' heads on other people's bodies, and CBS Chicago reported that officials said he took photos and videos of current and former students. Court documents reported by Patch say some images depicted girls he knew or should have known were under 13. At a detention hearing on 6 July a Lake County judge ordered him held pending proceedings, with a preliminary hearing set for 30 July 2026; no later development was found. The district superintendent told parents that supporting students' well-being was the immediate focus and that resources were being made available; authorities said they would keep affected families informed and connect them with support services. Officials initially gave a different first name for the teacher, corrected in later copy; he is not named here.

What Happened

According to the joint news release of the Libertyville Police Department and the Lake County State's Attorney's Office reported by the Lake & McHenry County Scanner (3 July 2026), students reported to school staff that they believed their teacher was video-recording students; a forensic examination by the State's Attorney's Cyber Lab 'revealed numerous images of students that had been altered using AI to create explicit images'; additional explicit child images were seized with the help of the State's Attorney's electronic storage detection K9 Grip and the Sheriff's Office ESD K9 Enzo; the State's Attorney approved multiple child-pornography charges, two of them Class X felonies and six Class 1; and prosecutors said they intended to petition to detain him in the Lake County jail while the case is pending. Police Chief Ed Roncone called it 'a highly sensitive, complex and lengthy investigation'; State's Attorney Eric Rinehart said 'Protecting children from exploitation and abuse is our top priority'. The Scanner's lede says authorities described the explicit images as created 'using videos he took of children in his class'; the Chicago Tribune (3 July) reports the State's Attorney's Office alleging that he created the images 'by using an AI program to digitally place the heads of students on the bodies of other people'; CBS Chicago (3 July) reports that officials said he took photos and videos of current and former students and used generative AI to alter them into pornographic images. The district superintendent's letter to District 70 parents, obtained by the Scanner and quoted by the Daily Herald, CBS Chicago and the Tribune, said the district became aware of the allegations on 3 June, the second-to-last day of school, when several students reported concerns to school leaders about inappropriate photos or videos allegedly taken by the teacher that afternoon in his classroom; that he was immediately removed from the classroom and placed on administrative leave that day; that the district contacted the police immediately and limited its public communication to protect the investigation; that supporting students' well-being was the immediate focus and resources were being made available; that board action was anticipated; and that the district would review its policy on staff use of personal technology and video recording. The Tribune adds that the district also contacted the Department of Children and Family Services. Patch (6 July 2026) reported from the State's Attorney's Office and court documents that the 44-year-old faces eight felony counts of child pornography, that the charges include allegations that some photos showed girls he knew or should have known were under 13, that detectives obtained his phone after students reported their concerns, that search warrants at his residence recovered multiple electronic devices, that a Lake County judge ordered him detained at a hearing on Monday 6 July, and that he was next expected in court on 30 July for a preliminary hearing. ABC7 Chicago (published 3 July, body dated 6 July) reported the arrest, the students' reports 'toward the end of the school year', the AI-altered images found on his phone, that he had been placed on administrative leave, and that officials would keep affected families informed and connect them with support services; it notes that officials initially gave a different first name. The reports do not say how many students appear in the images.

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

Eight felony counts of child pornography, two Class X and six Class 1 (Lake & McHenry County Scanner), approved by the Lake County State's Attorney's Office and filed in Lake County Circuit Court; the teacher surrendered to police on 3 July 2026, prosecutors said they would seek his detention pending the case, he appeared on 5 July, and at a detention hearing on 6 July 2026 a Lake County judge ordered him to remain detained, with a preliminary hearing set for 30 July 2026 (Patch, citing online court records). No later court development was found in the reporting read on 26 September 2026.

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 Libertyville 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

Henderson, Kentucky: police identified AI-generated nude images of two middle-school children on a device after a report that such images were being created and shown to other students at South Middle School; a juvenile was lodged at the juvenile detention centre on charges of distributing sexually explicit images without consent and possessing and distributing matter portraying a sexual performance by a minor

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. The tool is not named. The depicted children's exact ages are not reported, though the charge descriptors put them between 12 and 18.

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.

Carrizo Springs, Texas: a man was arrested in May 2026 after investigators say he used AI tools to turn photos from South Texas school pages into nude images of about 30 children, among more than 900 AI-generated abuse images and videos

Texas DPS announced on 29 May 2026 that a 31-year-old man from Carrizo Springs, Dimmit County, had been arrested and booked into the county jail on 19 May 2026 on a charge of possession of computer-generated child pornography, a charge DPS says was made possible by Texas Senate Bill 20. According to DPS, FBI agents in Del Rio searched his home in April 2026 and seized devices (DPS says with consent; ABC13 says under a search warrant) holding more than 900 AI-generated sexual images and videos of prepubescent and pubescent children that he had created, as well as non-AI sexual images of children. Investigators say he took photos of children from publicly accessible pages affiliated with South Texas schools and used AI tools to make nude images of them, and that about 30 child victims had been identified. The FBI is coordinating victim services. The allegations are charges; no later court development was found.

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.
