George Zimmerman trial live stream, update: Defense continues case in Trayvon Martin murder, more witnesses called to stand

Testimonies will resume today in the George Zimmerman murder trial of Trayvon Martin available via live stream below.

After nine days of testimonies, the prosecution rested its case on Friday but the defense will continue to call in witnesses to testify.

Last week, family members of both Zimmerman and Martin claimed that the person heard screaming for help in the background of a 911 call on the fatal day was their son.

The Feb. 26, 2012 call was played for the jury. When prosecutor Bernie de la Rionda asked Martin's mother Sybrina Fulton who she recognizes that voice to be, she replied, "Trayvon Benjamin Martin."

She said: "I heard my son screaming. I would hope for this to never have happened and he would still be here."

Jahvaris Fulton, Martin's brother, also testified that he heard Martin's voice on the 911 calls. "I didn't want to believe it was him," he said.

However, Zimmerman's father and mother both testified that the screams heard in the phone calls were from his son George.

On Friday, the prosecution had called medical examiner Shiping Bao to the stand. Bao performed the autopsy on Martin a day after his death and testified that the cause of death was from a gunshot wound to the chest. He testified that the manner of death was a homicide and that Martin had lived for up to 10 minutes and was in pain after he was shot.

Zimmerman has pleaded not guilty to the second-degree murder of Trayvon Martin, whom he shot to death in an altercation between himself and Zimmerman on his way back from a local convenience store last year. If he is found guilty, he will face up to life in prison.

The prosecution claims that Zimmerman who was an over zealous neighborhood watch volunteer who followed and shot Trayvon, while the defense claim that Trayvon aggravated Zimmerman who then shot him in self-defense.

The prosecution had also brought up Zimmerman's past in the trial, revealing Zimmerman's college coursework in criminal justice as evidence, which included a job application he made to a police agency in Virginia and to ride along with police officers in Stanford.

Through the 'evidence' provided, prosecutors hope to portray Zimmerman as having knowledge of the stand your ground laws, law enforcement, self-defense, and an overzealous wannabe cop who was looking for trouble when he shot Martin.

Prosecutors also brought up Zimmerman's interview with Fox News last year in which he says he did not know about the 'stand your ground' law before he shot Martin.

The defense called the evidence "irrelevant."

Zimmerman's attorney Mark O'Mara revealed in a press conference that the defense may ask the judge to consider allowing the jury to hear about Martin's past with fighting and marijuana use, saying that it was very surprising that prosecutors brought up Zimmerman's past in the case.

The defense had publicly released photos and text messages that alluded to Martin's past, but the judge ruled that it could not be brought up in the trial unless the defense proved that it was relevant.

Medical examiner Bao had testified that levels of marijuana was found in Martin's system and that it "could" have impacted Martin.

O'Mara said that he will try to prove to the judge that the evidence is relevant to the case.
