Defense attorneys are confident they can pick a jury in the Florida county where the neighborhood watch volunteer fatally shot 17-year-old Trayvon Martin in a gated community last year.

Zimmerman is pleading not guilty to second-degree murder, claiming self-defense.

Attorneys resume first-round of questioning Monday of potential jurors about their media exposure to the case that inspired protests nationwide. They've interviewed 41 prospects already.

A potential juror identified as juror H-13 said she believed Zimmerman approached Martin the night of the deadly confrontation.

 "I know Trayvon Martin was walking through that community or that complex and Mr. Zimmerman was doing a community watch and I believe called out to him," H-13 said.

H-13 said she wasn't sure what transpired after that, though "at some point there had to be an altercation between the two of them because Mr. Zimmerman was injured, but I don't know how that happened."

The woman said she believed Zimmerman continued to follow Martin after he was told not to by a non-emergency dispatcher.

Prosecutors and defense attorneys are seeking a pool of 40 potential jurors who have been screened for any influence of pretrial publicity before they move to a second round of questioning.

Attorneys are expected to continue questioning potential jurors until about 4 p.m., when the court will once again take up whether experts who analyzed a 911 call placed the night of the shooting will be allowed to testify, the Orlando Sentinel reports.

The screams in the background of a 911 call, placed by a neighbor, have been the subject of much debate. One state expert claims he heard Trayvon Martin saying "I'm begging you" in the background of the call, though other experts have said the quality of the tape renders it impossible to analyze.
