A Butler man was sentenced Wednesday in Common Pleas Court after pleading guilty to 50 felony charges of child pornography filed by state police following a tip from the National Center for Missing and Exploited Children in 2019.

Jon Doyle Somerville, 69, will serve 40 to 120 months in state prison and was ordered to register as a Tier 1 sexual offender under Megan's Law.

Somerville admitted responsibility and apologized to the court, family and friends before Judge Kelley Streib sentenced him.

“I was responsible and I'm sorry,” Somerville said.

His prison sentence included credit for 19 days already served in prison. He was placed in handcuffs and escorted from the courtroom by deputy sheriffs after the sentenced was handed down.

He was ordered to register with state police as a Tier I offender under Megan's Law for 15 years. Streib said he has to report his address, employment, phone number, vehicle ownership and internet communication address to state police and submit himself for monthly photographs under the terms of Megan's Law.

In addition to the 50 child pornography charges, he initially was charged with 20 felony counts of disseminating photographs of child sex acts and one felony count of criminal use of a communication facility. Those 21 other charges were not addressed during the sentencing hearing.

The offenses occurred in July 2019, and Somerville was arrested in June 2020 after police received a tip from the nonprofit National Center for Missing and Exploited Children through Snapchat.

The multimedia messaging app provided information through the center's CyberTip line that someone on July 18 and 19 had uploaded 43 images of suspected child pornography.

Police charged Somerville after they executed a search warrant and found more than 50 images of child pornography on a hard drive at his home.

Investigators used the internet provider address associated with the Snapchat account to help identify Somerville.
