Darryl Clark was 22 when he was fatally shot in Buffalo, New York, on May 12, 2015. His death came amid a sharp rise in violence across the city that year, when police recorded an unusually high number of homicides and struggled to investigate them all.

Clark’s shooting remains unsolved. No arrests have been announced and no suspects have been publicly identified, leaving his family without closure as one of more than half of that year’s killings that went unresolved.

If anyone knew Darryl, his routines, who he spent time with, or saw anything around May 12, 2015, please share information that might help bring answers.
