In the evening of August 6, 2017, 36-year-old Sandino Stone was shot and killed at the intersection of Robeson Avenue and Manassas in Memphis, near the Medical District.

Memphis police identified and arrested three suspects in the case. Terry Mason, then 26, was taken into custody and charged with first-degree murder in the course of a robbery. A second suspect, 28-year-old Demarcus M‑Dog Williams, was also arrested and charged with the same offense. A third man, 28-year-old Kenneth Gray, was located by the U.S. Marshals Task Force at a residence in Memphis and charged with first-degree murder in connection with the robbery and shooting.

Williams had a prior homicide-related case from 2006 in which he later pleaded guilty to lesser charges. Did anyone in Memphis know Stone or witness the robbery that night?
