Marquaan Dhonte Crosby was 17 when he was killed on the night of August 12, 2015, in Grand Rapids, Michigan. Crosby, a Black male, was walking with three friends near Adams Street and Marshall Avenue SE when someone approached and opened fire, striking him in the upper torso. He was taken to a nearby hospital and died of his wounds.

Investigators charged 21-year-old Sanqua Cummings in connection with the killing; Cummings was already in jail on unrelated charges in August 2015. In December 2016 a Kent County jury found Cummings guilty of first-degree murder, and he was also convicted of weapons and gang membership offenses. He received a mandatory life sentence without the possibility of parole. The Michigan Court of Appeals later upheld the conviction.

Did anyone who knew Marquaan or was in that neighborhood that night see something that could still help explain what happened?
