The mother of teenager shot and killed by a neighbourhood watch volunteer has testified that screams for help captured on audio of a police call came from her 17-year-old son.
Sybrina Fulton took the witness stand Friday morning during the trial of George Zimmerman, the former neighbourhood watch volunteer charged with murder in Trayvon Martin's shooting death. Zimmerman has pleaded not guilty and says he shot the teen in self-defence during a fight.
After the audio was played, prosecutor Bernie de la Rionda asked Fulton, "Who do you recognize that to be?" She replied, "Trayvon Benjamin Martin."
Identifying the screams on the police call could be critical to the case because it may help determine who was the aggressor during the scuffle between Zimmerman and Martin.
Under cross-examination, defence attorney Mark O'Mara suggested that Fulton may have been influenced by others who listened to the police call, including relatives and her former husband.
O'Mara also asked Fulton hypothetically whether she would have to accept it was Zimmerman yelling for help if the screams did not come from her son. He also asked if she hoped her son didn't do anything that led to his death.
"I heard my son screaming," Fulton said. "I would hope for this to never have happened and he would still be here."
Jahvaris Fulton, Martin's brother, also testified the screaming voice was that of Martin.
But O'Mara asked him why last year he had told a reporter that he wasn't sure if the voice belonged to Martin. Fulton, in explaining his comment to the reporter, told O'Mara he was "shocked" when he heard it.
"I didn't want to believe it was him," he said.
O'Mara asked to play the television interview for jurors, but Judge Debra Nelson denied his request for the time being.
Jahvaris Fulton's testimony was broken up by efforts to unlock the evidence room adjacent to the courtroom. Unable to open it, court officials called a locksmith with a drill to help them out.
Before testifying, Sybrina Fulton posted on Twitter "I pray that God gives me the strength to properly represent my angel Trayvon."
After the mother and brother testified, the doctor who performed an autopsy on Martin took the witness box. Associate medical examiner Shiping Bao started describing Martin as being in pain and suffering after he was shot, but defence attorneys objected. The judge sustained the objection, and Bao was directed away from that line of questioning.
He later estimated that Martin lived from one to 10 minutes after he was shot, and said the bullet went from the front to the back of the teen's chest, piercing his heart.
"There was no chance he could survive," Bao said.
Under cross-examination, defence attorney Don West questioned why Martin's hands weren't covered in order to preserve evidence on his fingers and why it took three hours to remove the body from the scene. West and Bao talked over each other at several points, requiring the judge to tell everyone to speak one at a time.
