A 54-year-old Port Byron man has been sentenced to 20 years in federal prison for possessing, receiving and distributing child pornography.

Scott Brian Griffith was sentenced Wednesday during a hearing in U.S. District Court, Rock Island, before U.S. District Judge Sara Darrow.

In addition to his prison term, Darrow ordered Griffith to serve 15 years on supervised release after he completes his prison term. There is no parole in the federal system.

Griffith also will be required to register as a sex offender.

He has been held in the custody of the U.S. Marshals Service since his arrest March 31, 2016.

Griffith was identified by law enforcement after he used multiple Twitter accounts to receive and distribute child pornography.

The U.S. Secret Service searched Griffith’s home on Dec. 15, 2015, and seized his computer. A forensic examination of the computer revealed the presence of images and videos of minor in sexually explicit conduct.

Griffith pleaded guilty on Jan. 19, 2017.

In addition to the Secret Service, the investigation was conducted by the Moline Police Department and the Illinois Internet Crimes Against Children Task Force.

The case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 to combat child sexual exploitation and abuse.
