Steven Glenn Christiansen, Child Sex Exploitation, Colorado 2025

A Colorado man was sentenced to 10 years in prison for his role in an online forum that worked to sexually exploit dozens of minor victims.

Steven Glenn Christiansen, 69, of Fort Collins, Colorado, used a mobile messaging application with end-to-end encryption to access 'invite only' group chats in which users exchanged images and videos of child sexual abuse material (CSAM).

The members used these groups to share livestreams and save files on third-party platforms, typically of minors engaged in sexually explicit conduct at the members' behest.

Christiansen communicated directly with other users to request and exchange CSAM.

After executing a residential search warrant at his residence, several digital devices were seized containing images and videos of CSAM, and the defendant admitted to possessing thousands of images.

Christiansen pleaded guilty in August 2025 to one count of possession of child pornography.

He was previously convicted in the state of Colorado in March 2000 for sexually assaulting a child.

Christiansen will serve 10 years in prison and lifetime supervised release.

Acting Assistant Attorney General Matthew R. Galeotti, U.S. Attorney Peter McNeilly for the District of Colorado, and Acting Special Agent in Charge Marvin Massey of the FBI Denver Field Office made the announcement.
