WICHITA, Kan. (AP) — A federal appeals court has upheld the 260-year prison sentence of a convicted child sexual predator who used a 9-year-old Kansas girl to produce pornography.

The 10th Circuit Court of Appeals ruled Tuesday that the sentence imposed on Philip Andra Grigsby, of Marquette, is justified.

U.S. District Judge J. Thomas Marten sentenced him in 2012. Grigsby had pleaded guilty to sexually exploiting a child, possessing child porn and illegally possessing a firearm as a convicted felon.

Investigators were led to Grigsby after child pornography found on an Australian man’s computer was traced to Kansas. Investigators identified the victim after noticing the name of a middle school on a physical fitness certificate.

Authorities found more than 400 images and five movies on Grigsby’s computer that showed the girl’s abuse.
