Jury seated, few issues to resolve before opening statements set for Monday in Zimmerman trial

With six female jurors now seated to consider whether George Zimmerman committed murder when he fatally shot 17-year-old Trayvon Martin, prosecutors and defense attorneys turn Friday to unresolved issues before next week's opening trial statements.

The jurors were sworn in Thursday for the second-degree murder trial of Zimmerman, a former neighborhood watch volunteer who says he fired on the unarmed black teenager in self-defense last year in a gated Florida community. Zimmerman is pleading not guilty.

Opening statements are scheduled Monday.

Issues to be resolved Friday include whether an audio expert can testify for the prosecution that screams captured on a 911 call belong to Martin. Circuit Judge Debra Nelson said she would make a decision Friday. Defense attorneys don't want the expert to testify, claiming his analysis is flawed.
