On Feb. 26, neighborhood watch volunteer George Zimmerman shot and killed 17-year-old Trayvon Martin as he was walking back from a convenience store in Sanford, Fla. Zimmerman claimed he shot the unarmed teen in self-defense and was released by the police shortly after the incident. The shooting set off a nationwide debate over race and justice. And on April 11, Zimmerman turned himself in after being charged with second-degree murder. On April 20, he was granted a $150,000 bond and left jail around midnight April 23. George Zimmerman appears before Circuit Judge Kenneth R. Lester Jr. during a bond hearing in Sanford, Fla., on April 20.
