JOPLIN (AP) – A federal judge has ruled a convicted sex offender from Joplin must serve 15 years in prison in a child pornography case.

The Joplin Globe reports 44-year-old Donnie Ray Sumner pleaded guilty last year to receiving and distributing child pornography over the Internet. Sumner had a prior conviction for possession of child pornography.

Authorities arrested Sumner in January 2013, after executing a search warrant at his residence and finding child pornography images on his desktop and laptop computers.
