CONCORD – Shane Niven, 34, of Nashua, will spend the next 10 years in prison after pleading guilty to possession of child sexual abuse material.

His sentence will be followed by eight years of supervised release. Niven was also ordered to pay $24,000 in restitution and a $5,000 special assessment.

Niven was identified through a series of tips received by the National Center for Missing and Exploited Children. According to federal authorities, Niven’s home IP address was used on two occasions to “share hundreds of files of suspected CSAM” with online users.

In April, federal agents found CSAM on Niven’s electronic devices. He is also a registered sex offender following a prior conviction involving the possession of such images.

“The defendant is a recidivist sex offender who continued his online exploitation of children,” said U.S. Attorney Jane Young. “This case highlights the importance of reporting child sexual exploitation to the National Center for Missing and Exploited Children. Cyber tips to NCMEC alerted law enforcement to the defendant’s nefarious online activity and potentially saved additional victims from harm.”
