Luis Matin, 29, was shot and killed on August 6, 2016, in Chicago during a month that would become one of the deadliest in recent city history. His death occurred amid an August that saw over 80 homicides and helped push 2016 toward roughly 500 homicides before the end of the summer.

Reports place Matin’s killing against a backdrop of rising gun violence concentrated in neighborhoods already facing economic and social challenges. Coverage at the time linked the city’s spike in shootings to factors including out-of-state firearms entering Chicago, gang-related conflicts and community distrust of law enforcement, all contributing to residents’ heightened fears.

If anyone knew Luis Matin or has information about what happened to him on August 6, 2016, please come forward.
