Police allege he used Grok to create the material from a photo of a teenage girl taken at a park. A Delaware County man has been arrested by Chester County police on charges of producing AI-generated child porn. West Goshen police said the department received information in June about “AI-generated content depicting the sexual abuse of a minor.” Police became aware of the images in June after Mayberry’s girlfriend contacted them about finding artificial intelligence images and videos on his mobile phone. Investigators found 76 AI-generated videos and 53 AI images indicative of child sexual abuse material.

The sources describe a person using a consumer AI app, not an autonomous agent, so no agent or failure-class fields were filled. No model version, developer, harness, safeguard state or controls that held or failed are stated, so no control links were recorded. The year of the June events is not stated in the sources and was not inferred, so no full dates were entered. Sources differ on the custody date, so the timeline gives both as reported. No loss amount, records count or count of affected parties is stated. The sources do not describe any remediation by the AI provider.
