SANFORD, Fla.   (AP) — More than 200 metro Atlanta residents are heading to Florida to join a rally over the shooting of an unarmed teenager by a neighborhood watch captain.

Civil rights activists have called for the arrest of the neighborhood watch captain, George Zimmerman, in the Feb. 26 shooting of 17-year-old Trayvon Martin in Sanford, Fla. Zimmerman has not been charged, and has said he shot Martin in self-defense.

WSB Radio reports (http://bit.ly/GP5GBN) that Atlanta City Councilman Derrick Boazman is among the leaders of the Atlanta group. They planned to leave Thursday morning from First Iconium Baptist Church in southeast Atlanta.

The Georgia protesters plan to join the Rev. Al Sharpton for what’s expected to be a massive rally Thursday night at a church in Sanford.
