Two men tied to Napa County are now at the center of a felony child sexual abuse materials investigation after authorities say their electronic devices contained images depicting sexual conduct by minors, including files deputies described as AI-generated. One man was arrested earlier this month by Roseville police and briefly booked into the Napa County jail, while another remains the subject of an outstanding warrant linked to a separate American Canyon search. Investigators say the case started with an outside tip and has involved coordination among local and federal agencies.
Court records show the Napa County Superior Court issued warrants for David Arthur Angelo Schreck and Payton Earl Stanfield on felony counts of possessing materials depicting sexual conduct by a minor, according to the Napa Valley Register. The filings list possession of matter depicting a minor engaging in sexual conduct as the felony charge named in the warrants.
Roseville police arrested Schreck last Tuesday after executing a search at a residence in that city, where officers say they found roughly 20 explicit images of underage children on seized devices, according to police arrest filings and county booking logs. Schreck was booked into jail at about 9:45 AM and released a few hours later after posting $50,000 bail.
AI-generated images seized in American Canyon search
Deputies served a search warrant at Stanfield’s American Canyon home on Nov. 20, 2025, and seized electronics that included two iPhones, according to a sheriff’s office report. Investigators say one device contained several hundred AI-generated pornographic images, many of which they described as consistent with depicting people under 18. On a second phone, deputies reported finding a note with AI prompt language that included the words “very young, teen” alongside sexual and torture descriptors.
Stanfield is additionally accused of creating obscene matter with artificial intelligence, and investigators say an FBI tip helped trigger the inquiry, as detailed by the Napa Valley Register.
What happens next
Warrants were filed in Napa County Superior Court, and records indicate Stanfield’s warrant had not been executed as of Tuesday afternoon, March 10. Prosecutors are expected to review the investigative reports and digital evidence before deciding whether to file formal charges. Because the case grew out of a cross-jurisdictional tip, officials say handling could continue to involve coordination between local investigators and federal partners.
Why this matters
Investigators and child safety advocates say AI-generated sexual imagery complicates both detection and prosecution, in part because synthetic files can look photorealistic and be created without a direct on-camera victim. A growing body of research and reviews of the legal and social implications of synthetic sexual imagery highlight how technology continues to outrun policy and investigative tools. A recent review in Social Sciences & Humanities Open and other studies note that lawmakers and platforms are scrambling to adapt enforcement, reporting, and detection systems to the new risks posed by generative AI.
