SANFORD, Fla. — A judge ruled Friday that attorneys for a Florida neighborhood watch volunteer can inspect the school records and social media postings of the unarmed teenager he is accused of killing.

Judge Debra S. Nelson said that defendant George Zimmerman’s attorneys need to know whether Trayvon Martin’s school records and social media postings give any evidence that he had violent tendencies.

Zimmerman, 29, fatally shot Martin, 17, in February. Zimmerman has pleaded not guilty to second-degree murder, saying he shot Martin in self-defense.

He was present Friday, his first appearance in public since his July bond hearing. He and his wife, Shellie, remain in hiding because of safety concerns.

The judge also said she would review Zimmerman’s medical records to see if they should be turned over to prosecutors. Nelson set another hearing for Oct. 26.

The judge has scheduled Zimmerman’s trial for next June. A hearing on Zimmerman’s self-defense claim has not been scheduled.
