Shippensburg Detective Indicted For Child Exploitation Offenses

HARRISBURG - The United States Attorney's Office for the Middle District of Pennsylvania announced that a Shippensburg Police Department Detective, Matthew S. Pleisse, age 36, of Shippensburg, Pennsylvania, was indicted on May 6, 2026, by a federal grand jury on child pornography charges. The case was unsealed following Pleisse's detention hearing.

According to United States Attorney Brian D. Miller, the indictment alleges Pleisse received, attempted to receive, and possessed child pornography on several dates between July 2024 and April 2025. It is alleged that Pleisse utilized cryptocurrency to purchase child pornography from the darknet and possessed child pornography depicting prepubescent minors.

"Homeland Security Investigations remains steadfast in its commitment to protecting vulnerable children and holding offenders accountable," said HSI Philadelphia Acting Special Agent in Charge Nathan Abel. "The indictment alleges that Pleisse utilized cryptocurrency to purchase and possess child sexual abuse material, actions that are reprehensible and illegal. HSI will continue to pursue those who exploit children online and work tirelessly to bring them to justice."

During Pleisse's detention hearing on May 19, 2026, Chief Magistrate Judge Daryl F. Bloom ordered Pleisse to be detained pending trial.

Homeland Security Investigations investigated the case. Assistant United States Attorney Stephen W. Dukes is prosecuting the case.

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 locate, apprehend, and prosecute individuals who sexually exploit children, and to identify and rescue victims.
