The trial of George Zimmerman, the man accused of slaying Florida teenager Trayvon Martin, will begin on June 10, a Florida Circuit Court decided Oct. 17.

Circuit Judge Debra Nelson, after conferring with attorneys in the case during a six-minute hearing, set the date for the trial, which should last about three weeks.

Though a trial date was slated, Zimmerman attorney Mark O’Mara was evasive when asked if he’d be fully prepared.

“I don’t know today when we’ll be ready for trial,” he told The Orlando Sentinel.

In a subsequent Twitter post, O’Mara said they will likely base Zimmerman’s defense on the divisive “stand your ground” principle and will seek an immunity hearing in the months before the trial.

“Zimmerman’s self-defense immunity hearing likely to be requested for April or May,” he tweeted.

Zimmerman, a 29-year-old neighborhood watch volunteer, is charged with second-degree murder for the shooting death of 17-year-old Martin, who was unarmed. The homicide ignited a firestorm of public condemnation and spawned civil rights rallies and campaigns across the nation.
