SANFORD, Fla. AP – Neighborhood watch volunteer George Zimmerman made his first court appearance Thursday on a second-degree murder charge in the shooting death of Trayvon Martin, as a court document provided new details on the prosecution’s case.

During the brief appearance, Zimmerman stood up straight, looked straight ahead and wore a gray prison jumpsuit. He spoke only to answer “Yes, sir,” twice after he was asked basic questions about the charge against him and his attorney.
