Stephan Hamilton, a 21-year-old Black man, was shot and killed on February 22, 2012, in Philadelphia, Pennsylvania. Police found his body after responding to reports of gunfire. No arrests have been announced and the case remains unsolved.

Hamilton’s death came during a year of heavy gun violence in Philadelphia, when firearms were used in over 85 percent of that year’s murders. Reports from the period note many homicide investigations struggled for evidence or witnesses willing to come forward, a pattern that investigators say has hampered efforts to clear similar cases.

Anyone who may have information about Stephan Hamilton’s killing is asked to contact Philadelphia authorities so this unsolved case can move toward justice.
