SANFORD, Fla. -- Attorneys in the George Zimmerman murder trial will again interview potential jurors Wednesday.

It is the third day for the jury selection process for a case that has a large following around the world.

Zimmerman has pleaded not guilty to second-degree murder charges for the February 2012 shooting death of 17-year-old Trayvon Martin in Sanford, Florida.

No jurors have been seated so far, and more than 70 have been let go from the initial jury pool of 500.

On Wednesday, attorneys hope to reach a smaller pool of 30 potential jurors so they can start asking more personal questions.

The interview process so far has focused mainly on pretrial publicity and the amount of news the potential jurors consume.

Of the 13 interviewed already, almost all of them have admitted to knowing something about Zimmerman, Martin or the case.

Although their identities are being withheld, the potential jurors so far have consisted of a variety of ethnic backgrounds, ages and both genders.

Juror "B51" is one with a Jacksonville connection. She said she has family there who expressed interest in the case, but that they never discussed it at length.

The woman, who said she was retired from a few different careers, also said she was surprised by the amount of media at the courthouse.

"Daunting," she described it.

One hundred jurors who were scheduled to show up for court on Wednesday have been told not to come. They are on call instead.

There is no timeline for when a jury needs to be seated. When it is, there will be six primary jurors and four alternates.
