UPDATE 2/9/2026: A Lexington Park, Maryland, man pled guilty in federal court today, to drug trafficking and weapons crimes.
Dominick Mackall, 37, is charged with possessing firearms and ammunition as a felon and possession with intent to distribute fentanyl and cocaine.
Kelly O. Hayes, U.S. Attorney for the District of Maryland, announced the guilty plea 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 the guilty plea, 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 — along with approximately $4,000 in cash. Additionally, law enforcement found reloadable government-benefit cards in other people’s names.
Mackall is facing a maximum of 15 years for the firearms charges. He also faces a minimum of five years and a maximum of 40 years in connection with the drug trafficking crimes. U.S. District Judge Deborah L. Boardman set sentencing for Wednesday, May 13, at 10 a.m.
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 are prosecuting this federal case.
