The process of selecting a jury in the George Zimmerman trial enters its fourth day Thursday, in central Florida.

Since Monday, 20 potential jurors have made it through questioning about pretrial publicity. Seventy-five others, from an initial pool of 500 Sanford, Fla.-area residents, have been deemed unsuitable to sit on the jury.

The attorneys have questioned an average of 20 jurors each day, trying to find 30 people during the initial phase, before moving on to more in-depth questioning.

Six impartial jurors and four alternates are needed for the trial to move forward. In Florida, 12 jurors are required only for criminal trials that could result in the death penalty. Zimmerman faces life in prison if found guilty.

Zimmerman, 29, stands charged in the death of 17-year-old Trayvon Martin. Zimmerman shot and killed Martin as the teen was walking back to the home of his father's fiancee from a Sanford convenience store on Feb. 26, 2012.

Defense attorneys argue that Zimmerman, then 28, was attacked by Martin while serving as a neighborhood watch volunteer. They contend that Zimmerman acted in self-defense when he shot the teen in the chest at point-blank range. Prosecutors have deemed Martin's death an instance of second-degree murder.

On Wednesday evening, Martin's father said he was happy with the jury selection process.

"We are encouraged as a family that we can get justice for our son Trayvon, and we expect the public to come forth and be honest as potential jurors," Tracy Martin said at a courthouse press conference.

The trial is scheduled to resume at 9 a.m. EST.

The judge is listing the jurors and asking both sides if they have peremptory strikes against any of them.

B12 - Strike by prosecution because of comments she made visiting Zimmerman's website.

B86 - Strike by prosecution because she said Trayvon had been expelled from school and shooting would not have occurred if that had not happened.

B29 - No strike.

E6 - Strike by prosecution because she said she was concerned about being sequestered and expressed an opinion about the difficulty of sending someone to prison. The judge denied the strike.

B76 - Strike by prosecution because she had asked why Martin was out late buying candy. The judge denied the strike.

B7 - Strike by defense.

B37 - No strike.

B51 - No strike.

E40 - No strike.

B35 Strike by prosecution.

E54 - No strike.

E73 - No strike.

M75 - Strike by defense. Defense said they are concerned because she is a friend and co-worker of a witness in the case and did not disclose it.

B72 - No strike.

E22 - Strike by defense. Defense concerned because she said police should have been more active and her pastor of 19 years, with whom she works for, wrote a "pointed letter" to the Orlando Sentinel that was "very pro-Trayvon." The pastor also allegedly gave a sermon that he was in favor of Martin's side. The defense said they consider her to be "somewhat stealth" because she did not disclose the information.

E13: No strike.

De la Rionda has asked to strike P67, for cause. The prosecutor said the potential juror has limited understanding of the English language and has said serving would be a hardship.

O'Mara objected. He said the juror can understand English.

The potential jurors are discussing their personal experiences with crime.

O'Mara is discussing Florida's "Stand Your Ground" law with the potential jurors.

"I don't think God gives us common sense ... I think we get common sense from our life experiences," O’Mara said.

The defense attorney was referencing a comment de la Rionda made to the jury yesterday, in which he said the jury should use their "God-given common sense."

"You make assumptions as you move through life [and] you have to be careful decisions you make on the outside don't come in [the courtroom]," O’Mara said.
