Jefferson Hills Man Sentenced to 15 Years in Prison for Federal Drug Trafficking and Firearms Offenses

PITTSBURGH, Pa. - A resident of Jefferson Hills, Pennsylvania, was sentenced in federal court to 15 years of imprisonment, to be followed by five years of supervised release, on his convictions of violating federal narcotics and firearms laws, Acting United States Attorney Troy Rivetti announced.

United States District Judge J. Nicholas Ranjan imposed the sentence on Alonzo Henry Griffin Jr., 24, on September 26, 2025.

According to information presented to the Court, on November 13, 2024, following the execution of a federal search warrant at Griffin’s residence, law enforcement recovered over 1,200 bricks of fentanyl, crack cocaine, two stolen and loaded semi-automatic pistols, and an AR-style semi-automatic rifle. Law enforcement also seized $4,500 in U.S. currency from the residence along with drug trafficking paraphernalia. With prior felony convictions that include a state drug trafficking offense and aggravated assault, Griffin is prohibited under federal law from possessing a firearm or ammunition.

Assistant United States Attorney V. Joseph Sonson prosecuted this case on behalf of the United States.

The Pennsylvania State Police Drug Law Enforcement Division Southwest Strike Force Unit and Federal Bureau of Investigation conducted the investigation that led to the successful prosecution of Griffin.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
