With more than three dozen people shot and seven dead, this past weekend marked the most violent in Chicago this year. Despite a decline in homicides after a particularly lethal 2012, the city has been marred by a number of horrific instances of gun violence, leaving innocent victims caught in the crossfire.

One victim, 15-year-old Hadiya Pendleton, was tragically shot and killed in a park in the city's South Side neighborhood. Her death added to the fury in the fight for gun control, as the death toll in Chicago and in city's around the country rose.

Hadiya's parents, Nathaniel and Cleopatra Pendleton, spoke with HuffPost Live host Marc Lamont HIll about the latest incidents of violence, calling the repeated instances "heart wrenching."
