SANFORD, Fla. -

Judge Debra S. Nelson ruled on Wednesday that George Zimmerman's school records showing his criminal justice courses, police job application and an application to ride around with Sanford police officers will be allowed in as evidence in his second-degree murder trial.

Nelson overruled the defense's objection to a college criminal justice course Zimmerman previously took that included course work on Florida's self-defense law, along with application records lacked relevancy.

The state will call a Seminole State College professor as a witness.

Zimmerman, a former neighborhood watch volunteer, has pleaded not guilty to second-degree murder. He says he shot Trayvon Martin, an unarmed black teenager, in self-defense.
