For prosecutors, the family’s testimony about the voice on the recording is key because it suggests that Zimmerman was the aggressor in the violent scuffle that led to Trayvon’s death. Their words were important for the state’s case because the judge refused to allow testimony from state audio experts who suggested the cries belonged to Trayvon.

For their final witness, prosecutors called Seminole Associate Medical Examiner Dr. Shiping Bao, who performed the autopsy on the teen.

Bao described Martin’s fatal injury — one bullet to his lower left chest that pierced his heart. He said Martin likely remained alive for one to 10 minutes after being shot, “still in pain, still in suffering.”

Jurors’ eyes were glued to the projector as autopsy photos were shown of Martin’s body and his bloodied sweatshirt. They passed around a bag containing bullet fragments taken from Martin’s chest.

In testimony, Bao also revealed that he was reading from private notes he had prepared in anticipation of his cross examination.

Nelson ordered the notes be provided to the defense, which then noted that Bao had only recently come to the conclusion that Martin could have survived for up to 10 minutes after the shot. He initially said up to three minutes.

Defense attorney Don West also noted that Bao changed his mind on whether marijuana found in Trayvon’s blood could have affected him that night — the doctor initially said it didn’t, but then backtracked.

But Nelson, sticking to a pretrial ruling, did not allow the defense to question Bao about the teen’s marijuana use.

Prosecutor Bernardo de la Rionda then announced the state was resting its case, but not before defense lawyer Mark O’Mara argued that the state hadn’t shown the “ill-will” or “hatred” needed to prove second-degree murder.

Prosecutor Rich Mantei shot back, saying the frustrated would-be cop’s calls to police — he remarked “these assholes always get away” on a recorded call to Sanford police to report Trayvon as a suspicious person — along with following Trayvon that night should be presented to the jury.

Mantei said only two people know what happened. “One of them is dead, one of them is a liar,” he said.

Nelson quickly ruled against defense lawyers’ request for an acquittal. The defense then called Gladys Zimmerman as their first witness, followed by Jorge Meza, an Orange County deputy who swore he heard the disputed 911 recording on TV and instantly knew it was his nephew.

“I felt his scream. It was George screaming for his life,” he said. “That voice just came and hit me. I felt it inside of my heart.”

After court recessed Friday for the weekend, O'Mara told reporters he wasn't sure if he would call Zimmerman to the stand as the defense prepares to present the rest of its case, possibly lasting until Wednesday or Thursday.

“I never thought that there was a proper case against George Zimmerman,” he said.
