Robert Caston, 36, was found fatally shot on June 28, 2016, in the 4000 block of Shelter Cove in the Oakhaven area of Memphis. Caston had been with a friend, Terrell Scott, and the two were smoking what Scott later said he believed to be a laced blunt. Scott reportedly became fearful and paranoid, concluded the marijuana had been tampered with, and then shot Caston.

A witness told police they had picked up Scott near the scene and that Scott had described the shooting to them. The Memphis Police Department arrested Scott and charged him with first-degree murder. Scott’s stated defense was that he acted out of fear, believing he had been drugged; he was scheduled for an initial court appearance on the murder charge.
