On January 9, 2016, 15-year-old Alder Hill was murdered while riding his bicycle home through Liberty City, Miami. He was ambushed, dragged into a grassy field, and shot multiple times in what police described as an execution.

Dozens of witnesses gathered at the scene and some posted images on social media, but according to investigators none have come forward with information, reportedly because of fear of retaliation. The case remains unsolved and underscores the barriers police face when a community is unwilling or afraid to cooperate.

If anyone knew Alder, saw him that day, or has information about what happened, please share what you know with the Miami police.
