It's been more than a month since Florida teen Trayvon Martin was shot dead by neighborhood watch captain George Zimmerman.
On Feb. 26, the 28-year-old watch captain shot dead the 17-year-old black teen as he was walking through the gated community to buy candy and iced tea from a convenience store.
Zimmerman told the police that he had shot Martin in self-defense after the teen attacked him. According to Zimmerman, the teen punched him on his nose and repeatedly banged his head on the sidewalk.
