Dangelo Brown was 26 when he and his brother, Justin Sims, were shot and killed during a family gathering in Indianapolis on July 2, 2016. Emergency responders pronounced both men dead at the scene after they sustained fatal gunshot wounds.

The Indianapolis Metropolitan Police Department opened a homicide investigation into the double killing.

Does anyone have information about that July 2, 2016 incident or remember seeing anything that night that could help investigators?
