About 10,000 people marched in Sanford, Florida, Monday calling for the arrest of George Zimmerman, the neighborhood watch volunteer who shot dead Trayvon Martin, an unarmed 17-year-old African American last month. The march occurred on a day filled with several developments in the case. The Orlando Sentinel is reporting Zimmerman told police that he shot Martin after the teenager punched him in the nose and began beating him. The altercation occurred after a 911 dispatcher told Zimmerman not to follow the teenager, whom he deemed to be suspicious. In another development, the Sentinel has revealed Martin was visiting his father’s fiancée in Sanford after he had been suspended from school in Miami because traces of marijuana were found in his book bag. Benjamin Crump is an attorney for Trayvon Martin’s family.

Benjamin Crump: “Whatever Trayvon Martin was suspended for had absolutely no bearing on what happened on the night of February 26. We told you previously, when you asked questions, that he wasn’t suspended for anything violent, and he wasn’t suspended for anything criminal. And if he and his friends experimented with marijuana, that is still completely irrelevant to George Zimmerman killing their son on the night of February 26.”

Trayvon Martin’s parents, Tracy Martin and Sybrina Fulton, spoke at a meeting in Sanford, Florida, on Monday.

Tracy Martin: “I would just like to say that, even in death — and Trayvon is gone. He will not be returning to us. Even in death, they are still disrespecting my son, and I feel that that’s a shame.”

Sybrina Fulton: “The only comment that I have right now is that they’ve killed my son, and now they’re trying to kill his reputation.”
