Kendall Joseph Mack was 32 when he died on September 18, 2012. His death was ultimately attributed to complications from a gunshot wound he suffered on November 13, 2007, in Southeast Washington, D.C., meaning officials later reclassified his passing as a homicide.

For nearly five years Mack lived with severe injuries from the 2007 shooting before those long-term effects proved fatal. The Metropolitan Police Department reopened the investigation after his death and announced a reward of up to $25,000 for information that leads to the identification, arrest, and conviction of the person or people responsible. No arrests have been announced and no suspects have been publicly identified.

Does anyone have information about the November 13, 2007 shooting or knew Kendall Mack that could help investigators?
