George Zimmerman Trial Live Stream: Defense Audio Experts Testify in Trayvon Martin Case (WATCH)

In a marathon court session that went until 8:30 p.m. jury selection continued for most of the day until testimony was heard to determine if a 911 call should be admissible during the George Zimmerman murder trial, according to the Orlando Sentinel.

Jury selection continues to drag along at a ponderous rate as only four jurors were chosen to return. Attorneys continue to have high hopes that they can narrow the jury pool down to 40 potential jurors and start the second phase of jury selection with traditional questions as early as Tuesday, according to the Orlando Sentinel.

The drudgery of jury selection was set aside for a bit as Judge Debra Nelson listened to testimony from a defense biometrics expert, James Wayman, about the 911 call that could serve as key piece of evidence in the case. Screams for help are heard in the background of the call made by a neighbor who witnessed the altercation between Zimmerman and Trayvon Martin, experts for the prosecution testified two weeks ago that the voice screaming is Martin's. Wayman testified that the state's experts are incorrect because the methods they used are faulty, according to the Orlando Sentinel.

"This is a fragile technique," Wayman said. "That is not enough data...to do any reliable estimation of who the speaker is."

Defense attorneys want to prevent state experts from testifying during the trial. One of the experts for the state, Tom Owen, is going to testify again on Wednesday. Judge Nelson is expected to make a decision after his testimony.

One of the potential jurors screened and dismissed on Monday admitted that they had donated money to Zimmerman's defense fund. Another potential juror, H-29, said that he was irritated by the protests surrounding the case.

"We had a little circus come to town, with celebrities...That quite honestly turned me off," Juror H-29 said. "This is a tragic case. There are no winners here."

After the late night in court the trial resumes Tuesday morning at 9:00 a.m. EST. To watch a live stream click here.
