LINCOLN, Neb. (AP) — A federal appeals court has upheld the 30-year sentence a Nebraska man received last year for making child pornography.

The 8th U.S. Circuit Court of Appeals rejected Billy Schrader’s argument that his sentence was unfair because his girlfriend was sentenced to 23 years in the same crime.

Schrader and Julia Thiemann, were arrested in December 2013 in North Platte on several porn allegations. Authorities say a child told investigators that Schrader had sex with her and that Thiemann participated and took pictures.

Both Schrader and Thiemann pleaded guilty to making child pornography.

The judge who sentenced Schrader said the longer sentence was supported by videos the couple made that showed Schrader performing most of the physical acts.

The appeals court said Monday the sentencing judge didn’t make a mistake.
