LEONARDTOWN, MD (November 17, 2025) – State’s Attorney Jaymi Sterling announced today that Mark Albert Fenwick Jr., 33, of Annapolis, Maryland, was sentenced to LIFE in prison, with 40 years of active incarceration for his role in a 2024 shooting in Lexington Park that left a victim with multiple gunshot wounds.

 

Following a multi-day jury trial that concluded in May 2024, a St. Mary’s County jury found Fenwick guilty of attempted first-degree murder, first-degree assault, armed robbery, and theft.
