The attorney for the man who fatally shot Trayvon Martin says he is shutting down a Facebook page the defense team was using because it was leading to unhelpful discussions.

Attorney Mark O'Mara announced the decision Wednesday on a separate website set up to distribute information on George Zimmerman's defense. Zimmerman is charged with second-degree murder in the shooting and has pleaded not guilty. He claims he shot the unarmed teenager in self-defense.

O'Mara says the Facebook page served several purposes over the past three months, including giving Zimmerman and the defense team an official social media presence. But O'Mara says it also allowed for discussions of evidence and Zimmerman's guilt or innocence.

The website GZlegalcase.com is still active.
