WOODBURY - It's been one year since a neighborhood watch leader fatally shot an unarmed Florida teen.

George Zimmerman killed 17-year-old Trayvon Martin in Sanford, Fla. last year. Zimmerman claims he shot the unarmed teen in self-defense.

Martin's family held a candlelight vigil in Union Square Park to mark the first anniversary of their son's death. They asked attendees to wear hoodies like the one Martin was wearing the night he was killed.
