A gunman opened fire at a family party on Chicago\'s South Side, wounding four people, including an 11-year-old child, police said. Police said the shooting Sunday night was about a block from the scene of a fatal shooting earlier in the day, but that it was too soon to tell whether the incidents were related, the Chicago Tribune reported Monday. Earlier in the day, a man was found dead in a car parked in a school parking lot, police said. The Sunday night incident brought to a close another violent Chicago weekend in which two people were killed and 24 injured since Friday night, WMAQ-TV, Chicago, said. Chicago Mayor Rahm Emanuel, speaking on NBC\'s \"Meet the Press\" Sunday, said the city was \"making efforts\" to reduce gang conflict. He rejected the thought that Chicago was in a crisis. \"[We\'re] containing it,\" Emanuel said in an interview from Charlotte, N.C., where he is attending the Democratic National Convention this week. \"I\'m going to do everything I can to make sure every child, when they\'re going to school, can think about their studies not their safety, regardless of where they live, and that\'s my first priority.\"
