OMAHA, Neb. (AP) — An Omaha man has been sentenced to 35 years in prison for filming himself raping a 13-year-old child.

Federal prosecutors for Nebraska say in a news release that 38-year-old Steven Carlson was sentenced Friday in Omaha’s federal court. Upon his release, he will be subject to a lifetime of supervision. There is no parole in the federal system.

Carlson pleaded guilty in February to one count of production of child pornography.

Prosecutors say as part of the plea, Carlson admitted that in May 2016, he filmed himself forcibly sexually assaulting a 13-year-old nonverbal child. Officials say a search warrant executed on Carlson’s home resulted in the discovery of hundreds of images of child pornography involving minors as young as infants.
