The medical examiner who conducted the autopsy on Trayvon Martin's body testified today that the Florida teenager lived from one to 10 painful minutes after he was shot in the heart by George Zimmerman, and that the wound was impossible to survive.
Dr. Shiping Bao testified after Martin's mother and brother took the stand as the prosecution nears completion of its case against Zimmerman.
Bao told the court that Martin, 17, was shot in the heart and said, "There was no chance he could survive."
The medical examiner said that Martin would have lived anywhere from one minute to 10 minutes after being shot as his beating heart ran out of blood to pump.
"His brain is still alive?" prosecutor Bernie de la Rionda asked.
"Yes," Bao replied.
"He can still feel pain in other words?" the prosecutor asked.
"Yes," he replied.

De la Rioda asked whether Martin would have been able to move after he was wounded.
"From my experience and another autopsy we did three weeks ago, I don't believe he could move," Bao said.
Bao's claim that Martin would have been unable to move could cast doubt on Zimmerman's version of what happened during their violent confrontation on Feb. 26, 2012.
Zimmerman, who is being tried on charges of second degree murder, has maintained that he shot Martin after he was knocked down and beaten by Martin and the teenager went for Zimmerman's gun. After the shot was fired, Martin sat up and said, "You got me," Zimmerman told police and media.
Bao's claim that the wound would have immediately incapacitated Martin is the latest example of what the prosecution says are discrepancies in Zimmerman's version of what happened that night
Bao's testimony followed the mother and brother of Martin who both took the stand and told jurors that they could hear him scream for help on 911 calls made just before he died.
"That scream, do you recognize that?" de la Rionda asked Martin's mother, Sybrina Fulton.
"Yes, it's Trayvon Benjamin Martin," she answered.
Prosecutors hoped that the testimony of Martin's mother and brother may have an emotional and convincing impact on the jury and that the jurors would tie their words to the opinion of FBI audio expert Hirotaka Nakasone who testified earlier in the trial that it was not possible to definitively identify the voice using available acceptable technology.
Nakasone said the best person to identify the voice would be someone who is intimately familiar with the voice.
During cross examination defense attorney Mark O'Mara asked Fulton if she hoped it would be her son, because if it wasn't her that could mean he was responsible for his death, O'Mara said.
"I heard my son screaming," Fulton replied. "I didn't hope for anything. I simply listened to the tape."
It's not clear what impact it could have the jury, which consists of six women.
A major point of contention in the trial is who was heard screaming for help in the background of 911 tapes the night Martin was killed. Fulton claims it was her son, while Zimmerman's father insists that it is his son's voice that is heard.
Moments before she began her testimony, Fulton tweeted, "I pray that God gives me strength to properly represent my Angel Trayvon. He may not be perfect but he's mine. I plead the blood of Jesus for healing."
Trayvon Martin's brother, Jahvaris Fulton, also told the jury that the voice on the tape was that of his brother.
