Samuel Huff, 67, was shot and killed in the early evening of September 4, 2016, while walking near a public housing apartment complex in Nashville. He was a familiar, well-liked presence in the neighborhood who took regular walks; his routine ended suddenly with the fatal shooting.

Surveillance did not capture the shooting, but nearby video showed a man later identified as Javaris Wilson running up behind Huff moments before the shot. Eyewitnesses placed Wilson with the victim, and a single .40-caliber cartridge casing was recovered from the street at the scene. Months after the killing, Wilson was arrested and charged with Huff’s murder.

A jury found Javaris Wilson guilty of first-degree premeditated murder and imposed a life sentence, a judgment later upheld on appeal. Did anyone in the neighborhood know Samuel’s routines or see anything that evening that wasn’t already reported?
