President Obama, in his State of the Union speech Tuesday, called attention to the sad tale of Hadiya Pendleton, the innocent 15-year-old girl gunned down by gang gunfire in a case of mistaken identity and yet another tragic bit of Chicago gun violence.

Obama, in telling Hadiya's story, mentioned that she died just a mile from his house.
