Marquil Carter, 25, was found fatally shot on September 9, 2018, in an apartment near 140th and Indiana in Riverdale, Illinois. His father, Vincent Martin, 61, was also shot and killed in the same apartment. A toddler, Marquil’s 2-year-old son, was found unharmed in the residence.

Police say the shooter was able to enter the apartment without a struggle, which led investigators to believe the victims might have known the assailant. No suspects were immediately identified and no arrests were reported in the days following the discovery. Family members described both men as wonderful people who had no known enemies, and relatives urged anyone with information to contact investigators.

The Riverdale Police Department has the case open and continues to seek tips from the public. If anyone knew Marquil or Vincent, or saw anything unusual near 140th and Indiana around September 9, 2018, please come forward.
