Diqwun Lavell Martin was a 19-year-old Black man from Meridian, Mississippi, who had graduated from Meridian High School the year before he died. His family remembered him as sweet, funny, and always cracking jokes and said some friends he kept had led him into situations he likely would not have been in.

Diqwun was last seen on August 27, 2020. His family reported him missing later that month, and on September 3 his body was found in a wooded area behind an abandoned house on 25th Court in Meridian. Investigators determined he had been shot and left for dead.

The case produced no suspects for over a year. In April 2022 Meridian police arrested two men, Onorious Campbell and Myson Mosley, each 21, on first-degree murder charges; a third man, Jakavion Adams, 22, was later charged with murder and possession of stolen property. In August 2024 Onorious Earl Campbell was arrested on a capias warrant for failure to appear related to the homicide; the murder charges remained pending in court.

If anyone knew Diqwun, his activities in late August 2020, or has information about what happened on or near 25th Court, please come forward to investigators.
