3/11: Malaysia Airlines mystery: Frustration grows as search area expands; Chicago poet gives voice to community entrenched in violence

Four days into the search for Malaysia Airlines Flight 370, no clues have emerged as to what happened to it. The confusion deepened Tuesday when a Malaysian newspaper quoted the country's air force chief as saying the plane may have changed course; and, Malcolm London lives in Chicago's Austin neighborhood, a part of the city that doesn't usually inspire verse. The 20-year-old started writing poems in 2009 to give his community a voice. He now takes his message to public school classrooms and can be seen performing for national audiences.
