Marcus E. Alston was 20 when he was killed in East Baltimore on the evening of April 10, 2019. Gunfire near East North Avenue also killed 21-year-old Diarah Baxter; a 19-year-old man was wounded with a gunshot to the leg.

Investigators later connected this double homicide to a retaliatory quadruple shooting in the Mondawmin area that occurred on April 11, 2019, and said evidence placed a vehicle belonging to Donte Patterson at the scene of both incidents. That link became central to the investigation into the string of shootings in April 2019.
