WILLIAMSPORT – The United States Attorney’s Office for the Middle District of Pennsylvania announced that Robert Mansberger, age 59, of Cassville, Pennsylvania, was sentenced on January 14, 2025, by U.S. District Court Chief Judge Matthew W. Brann to 102 months of imprisonment and 10 years of supervised release on the charge of attempted enticement of a minor. 

According to Acting United States Attorney John C. Gurganus, on November 10, 2023, law enforcement conducted an undercover operation during which they advertised an online ad

on a known website that publicized sexual services of minors. Mansberger responded to the ad through multiple messages indicating he wanted to engage in sexual activity with a 13-year-old minor.

The case was investigated by the Federal Bureau of Investigation, the Pennsylvania State Police, Patton Township Police Department, the Centre County District Attorney’s Office, Williamsport Police, and the Lycoming County District Attorney’s Office.  Assistant U.S. Attorney Alisan V. Martin prosecuted the case.
