A rally expected to draw thousands of Trayvon Martin supporters was scheduled for Sunday at Bayfront Park in downtown Miami.
Martin, the 17-year-old Miami Gardens high school student, was shot by neighborhood watch volunteer George Zimmerman in February.
Martin's parents, Rev. Al Sharpton, Rev. Jesse Jackson and local lawmakers will be at the rally, organized by Congresswoman Frederica Wilson.
Grammy Award winning artist Betty Wright will be singing a song at the rally that she wrote on behalf of her late son who was shot in 2005.
The rally, which is expected to draw 75,000 people, will be at 301 N. Biscayne Boulevard at 4 p.m.
The Miami Gardens teen was visiting with his father at his father's girlfriend's home in a gated Sanford community and had gone to buy a bag of Skittles and iced tea at a nearby convenience store. He was walking back when the shooting happened.
Though Martin was unarmed, Zimmerman told police the shooting was self-defense, and no charges have been filed in the case.
Florida Gov. Rick Scott has appointed a special prosecutor to oversee the investigation into Martin's death. The FBI and U.S. Justice Department are also investigating the shooting.
The shooting has led to numerous marches and protests throughout South Florida and across the country, as Martin's family and supporters demand Zimmerman's arrest.
