On the evening of October 22, 2015, 19-year-old Cameron Selmon of Memphis was killed in a burst of gunfire in an outdoor courtyard on the Tennessee State University campus in Nashville. Three other people were wounded in the shooting. Selmon was not a student at the university.

Reports say the violence began with a dispute over a dice game that escalated into a physical fight before two individuals opened fire; surveillance footage captured the moment the shots were fired. After a ten-month investigation, a Davidson County grand jury indicted two men and authorities arrested 20-year-old Christopher Gatewood and 20-year-old Robert Tunstall in Memphis in August 2016. The indictments included first-degree murder, three counts of attempted second-degree murder and three counts of aggravated assault among other charges. Tunstall was on parole for a prior robbery and theft conviction at the time of his arrest; Gatewood was taken into custody at his mother’s residence.

Did anyone witness the dispute or the courtyard surveillance footage that night?
