Justin Sims was 32 when he was shot and killed during a family gathering in Indianapolis on July 2, 2016. The gathering had been held in the wake of the brothers’ father’s funeral; Justin’s younger brother, 26-year-old D’Angelo Brown, was also fatally shot in the same incident. A three-year-old child was injured in the violence.

No public announcements about arrests, suspects, or a motive have been released, and few details about the investigation have appeared since the killings. The deaths turned a day of mourning into further tragedy for the family and left unanswered questions about who carried out the attack and why.

If anyone was at that gathering or has information about the shootings, please come forward to the Indianapolis authorities.
