MIAMI (AP) -- Political leaders, sport stars, entertainers and several thousand people have taken part in a rally in Miami to support the family of an unarmed Florida teenager shot and killed by a neighborhood watch volunteer.
Basketball stars Alonzo Mourning and Isaiah Thomas, singers Chaka Khan and Betty Wright, and others joined the parents of Trayvon Martin in calling Sunday for justice in the case.
Martin's father promised the crowd that he would not stop fighting "for my Trayvon and for your Trayvon."
The rally came a day after thousands marched through Sanford, the central Florida town where 28-year-old George Zimmerman shot and killed 17-year-old Trayvon Martin in February. Zimmerman has claimed self-defense and has not been arrested.
Martin was black. Zimmerman's father is white and mother is Hispanic.
State and federal authorities are investigating.
