Alberto Martinez, 55, was fatally shot in a drive-by on the early morning of Halloween 2021 while sitting in his 2017 Dodge Ram at 147th Street and Frederick Douglass Boulevard in Harlem. Multiple rounds struck the driver’s side; Martinez, of Puerto Rican descent, was hit several times in the chest and arm, managed to drive a few blocks and then crashed into a parked car before being taken to a hospital where he died.

Identification on his body bore the name Abraham Rodriguez, the alias he reportedly used while living in Maine in the federal witness protection program after testifying against former associates. He had recently returned to Harlem. Witnesses said Martinez tossed baggies believed to be heroin from his truck after he was shot. Initial reports named no arrests.

Investigators later charged 27-year-old Shakeem Parker in connection with the shooting, alleging a months-old road rage grudge rather than retaliation for Martinez’s past as a trafficker and informant. Parker was acquitted in July 2024, and the question of who killed Martinez remains unresolved. Does anyone have information about Martinez’s movements in Harlem in the weeks before Halloween 2021?
