Courtney Blacksher, 43, was found dead from gunshot wounds in her fourth-floor apartment on Harry S. Truman Drive in Upper Marlboro, Maryland, on the afternoon of September 28, 2023. She was a metro bus driver and a mother of two, survived by a son in his 20s and another child under the age of 10.

Investigators identified her boyfriend, 43-year-old Keith Maybin, Jr., as a person of interest. Hours after Blacksher’s body was discovered, Seat Pleasant police took Maybin into custody following an unrelated allegation that he threatened two people with a gun. He was later charged with first- and second-degree murder, assault, and related counts, and held without bond. Authorities described the case as a domestic-related murder, and the Prince George’s County Police Department Homicide Unit continues its investigation.

If anyone knew Courtney, her movements that day, or has information about the events at the apartment, please share what you know with investigators.
