Florida judge has denied defense requests to end 24-hour GPS monitoring of George Zimmerman while he is out on bond in the fatal shooting of Florida teenager Trayvon Martin.

Judge Debra Nelson denied bond requests from Zimmerman's defense team Tuesday. Besides dropping the monitoring, the defense wanted the former neighborhood watch volunteer to be able to live outside Seminole County.

Zimmerman is charged with second-degree murder in the 17-year-old Martin's shooting following an altercation in Sanford in February. He has pleaded not guilty, claiming self-defense under Florida's "stand your ground" law.

Nelson has set a trial date for June 10. He also set a "stand your ground" hearing 45 days before trial where Zimmerman can argue it was self-defense and ask the judge to drop the charges.
