Luis Alberto Diaz, a 23-year-old Hispanic male, was reported missing by his family on July 8, 2015, in Antioch, Tennessee. His body was later found in Rockvale, Tennessee. Investigators determined Diaz was fatally shot during a drug deal that had been arranged in Antioch.

Police arrested 22-year-old Joshua A. Smith of Antioch and charged him with criminal homicide, alleging Smith arranged the drug deal and, with another unidentified individual, shot Diaz in his vehicle before dumping the body in Rockvale. Smith told police that the other person fired the fatal shot. Two other suspects were implicated: James Jaylen Simmons, who pleaded guilty to second-degree murder and received a 40-year sentence, and Xavier Young, who was charged with first-degree murder and had not been scheduled for trial as of the latest updates.

Diaz’s family publicly expressed grief and forgiveness and said they hoped to move forward with healing hearts. Does anyone have information about the events in Antioch on July 8, 2015, or about Diaz’s movements that day?
