Stars join Miami protest over killing of Florida teen Political leaders, sports stars and entertainers were among several thousand people who gathered Sunday at a Miami rally to call for an arrest in the fatal shooting of an unarmed Florida teenager by a neighborhood watch volunteer. The demonstration in 17-year-old Trayvon Martin's hometown was one of the largest yet and drew basketball stars Alonzo Mourning and Isaiah Thomas, singers Chaka Khan and Betty Wright, politicians and civil rights leaders. Martin's father, speaking briefly, promised the crowd he would not stop fighting "for my Trayvon and for your Trayvon." "Each and every one of us feels the pain of this family simply because Trayvon Martin could have been one of all of us," said Mourning, the former Miami Heat player. Many supporters wore hooded sweat shirts like the one Martin was wearing when he died. Among them: Mourning's 15-year-old son, Trey. "It could have been me," Trey Mourning told the crowd. A day earlier, thousands marched through Sanford, the central Florida town where 28-year-old George Zimmerman, a neighborhood watch volunteer, shot and killed Martin in February. Martin was walking back from a convenience store, where he had gone to buy candy and iced tea, when he and Zimmerman got into an altercation. Zimmerman says he was attacked and has claimed self-defense; Martin's family disputes his version of events.
