For Immediate Release
U.S. Attorney's Office, Western District of Pennsylvania

JOHNSTOWN, Pa. – A resident of DuBois, Pa., pleaded guilty in federal court to a charge of possession of child pornography, United States Attorney Cindy K. Chung announced today.

William R. Mumma, 32, pleaded guilty to a one-count Information before Senior United States District Judge Kim R. Gibson.

In connection with the guilty plea, on or about Oct. 26, 2017, to on or about Sept. 12, 2018, Mumma possessed images of minors engaged in sexually explicit conduct, which were produced using prepubescent minors engaging in sexually explicit conduct. The computer graphic files were shipped or transported in interstate or foreign commerce.

Judge Gibson scheduled sentencing for September 14, 2022, at 10:30 a.m. The law provides for a maximum total sentence of 20 years in prison, a fine of $250,000 or both. Under the Federal Sentencing Guidelines, the actual sentence imposed would be based upon the seriousness of the offense and the prior criminal history, if any, of the defendant.

Assistant United States Attorney Arnold P. Bernard, Jr. is prosecuting this case on behalf of the government.

The Laurel Highlands Resident Agency of the Federal Bureau of Investigation conducted the investigation that led to the prosecution of Mumma.

This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by the United States Attorneys' Offices and the Criminal Division's Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state and local resources to better locate, apprehend, and prosecute individuals who sexually exploit children and to identify and rescue victims.
