Maryland Man Sentenced to More Than Nine Years in Federal Prison for Firearm And Drug Trafficking Crimes

Greenbelt, Maryland - A Maryland man learned his fate in federal court, today, in connection with drug trafficking and weapons crimes.

U.S. District Judge Deborah L. Boardman sentenced Dominick Mackall, 37, of Lexington Park, to 110 months in prison, followed by four years of supervised release, for possessing firearms and ammunition as a felon and possessing with intent to distribute fentanyl and cocaine. Judge Boardman also entered an order that Mackall forfeit all his firearms, ammunition, and $4,298 in cash.

Kelly O. Hayes, U.S. Attorney for the District of Maryland, announced the sentence with Special Agent in Charge Charles Doerrer, Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), and Sheriff Steven A. Hall, St. Mary's County Sheriff's Office.

According to court documents, on October 26, 2022, law enforcement executed a search warrant at Mackall's residence and took him into custody in connection with a five-month narcotics trafficking investigation. During the search, law enforcement discovered multiple loaded firearms, including a ghost gun, and numerous rounds of ammunition in Mackall's bedroom. Mackall is a convicted felon, so he is prohibited from possessing a firearm or ammunition.

Law enforcement also uncovered several controlled substances in different quantities - including 964 fentanyl pills, cocaine, and marijuana - $4,298 in cash. Additionally, law enforcement found reloadable government-benefit cards in other people's names.

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.

U.S. Attorney Hayes commended the ATF and St. Mary's County Sheriff's Office for their work in the investigation. Ms. Hayes also thanked Assistant U.S. Attorney Joel Crespo and Special Assistant U.S. Attorney Brittany Appleby-Rumon who prosecuted the case.
