Andrew David Duncan was 20 when he was shot and killed on September 23, 2016, near Richmond Raceway in Henrico, Virginia. Reports say the shooting followed an argument; initial accounts did not elaborate on what caused the dispute.

Henrico police identified a suspect and arrested 25-year-old Akeem Darnado Young on a murder charge. The case went to trial, where prosecutors presented evidence linking Young to the killing. In August 2017 a Henrico County jury convicted Young of first-degree murder; the jury also recommended 30 years for the murder and three additional years for a felony firearm count. Young protested his innocence in court during the conviction, and he was formally sentenced in November 2017.

Are there details about the argument or witnesses from that night that anyone can add?
