ST. LOUIS – A man from Webster Groves, Missouri on Tuesday admitted sending and receiving child sexual abuse material online.

Joseph A. Seiffertt, 44, pleaded guilty to one count of possession of child pornography. He admitted possessing 43 images and 433 videos containing child sexual abuse material (CSAM) on his cell phone, as well as AI-powered apps that he used to depict clothed individuals, including minors, in the nude. Seiffertt also discussed the sexual abuse of minors with someone online and shared and received CSAM via the Kik Messenger app.

Seiffertt is scheduled to be sentenced on March 11, 2026. The U.S. Attorney’s Office will recommend a sentence of 12 years in prison, followed by a lifetime on supervised release.
