[Updated at 5:12 p.m. ET]
Prosecutor Bernie De la Rionda begins cross-examination. He asks Meza how much details he knows about Zimmerman's case. Meza says that because of his position in the Sheriff's office, he tried to stay out of the case as much as possible.

Prosecutor Richard Mantei rests. O'Mara starts his rebuttal.
[Updated at 4:14 p.m. ET]
Mantei argues that pointing a loaded weapon at the heart and pulling the trigger "is in fact evidence of ill will." He responds to O'Mara's argument about ill will, saying that Zimmerman thought he knew who Martin was and that his was wrong in his assumption. He also presents several exhibits of direct evidence of Zimmerman's ill will and calls Zimmerman a liar. He, too, cites law cases that suggest Judgment of Acquittal is not appropriate in this case.
[Updated at 3:59 p.m. ET]
Defense attorney Mark O'Mara just finished arguing Judgment of Acquittal before Judge Debra Nelson. Prosecutor Richard Mantei responds.
[Updated at 3:38 p.m. ET]

[Updated at 2:16 p.m. ET]

[Updated at 2:13 p.m. ET]
West asks Bao if it was his conscious decision not to photograph Martin's palms. Bao answers that during an autopsy, he looks for something significant, like injuries or disease, and doesn't photograph the body part if there is nothing significant.

[Updated at 2:04 p.m. ET]
West asks Bao about blood drawn for Martin's toxicology report. in this case, Bao says, blood was drawn from Martin's chest for the toxicology report. He explains that normally, they try to get peripheral blood first, but in Martin's case, there was no blood left anywhere but his chest.

[Updated at 1:42 p.m. ET]
West asks the medical examiner, "When did you change your mind on the significance of levels of THC on Martin's mind?" Bao answers, "In the last 60 days." He also says he spent hours doing additional research and speaking with fellow experts to come to the new conclusion that marijuana may have had an effect on Martin.
[Updated at 1:38 p.m. ET]

The defense attorneys grin while reviewing Bao's notes. From the witness stand, the medical examiner asks, "Is there something funny there?"
[Updated at 11:50 a.m. ET]

[Updated at 11:46 a.m. ET]
West asks if Martin's wet clothes were sealed in a plastic bag before examination. "If anybody does that, he'll be gone the next day. This is a very basic concept," Bao says. He adds that it's standard procedure to use a paper bag instead of a plastic bag for clothing.
[Updated at 11:38 a.m. ET]
West and Bao argue about his not responding to West's question about the autopsy time line. Judge Nelson tells the witness to "please stop speaking so Mr. West can ask the next question."

Bao describes the path of the bullet: "Perforations of anterior wall of space between 5th and 6th ribs.

[Updated at 9:22 a.m. ET]

The tape is played while the jury remains out. The reporter asks, "Who did you hear?"
Fulton: "I'm not sure. Honestly, I haven't even listened to it that good. I've heard it. I would think it was my brother, but I am not completely positive that it is him."
The interview was on March 31, 2012.
[Updated at 9:15 a.m. ET]
O'Mara says the tape should be played because Fulton has not sufficiently answered the question about what he told a Miami TV reporter. He moves for the impeachment of Fulton.

[Updated at 9:11 a.m. ET]
"When I heard it in the mayor's office (for the first time), I guess I didn't want to believe it was him," Fulton says. "I was clouded by shock and sadness." O'Mara says the interview he gave was two weeks after that first listen. Fulton says he did not hear the tape again in the interim.
[Updated at 9:10 a.m. ET]
Mark O'Mara recalls Fulton's interview where he once said he was not initially certain whose voice was screaming.

O'Mara to Fulton: "You certainly hope, as a mom, that your son Trayvon Martin would not have done anything that led to his death, correct?" Fulton replies, "What I hoped for is that nothing happened and he'd still be here. That's my hope." Then says "I don't believe he was" responsible for his own death. Fulton is excused from the stand.

The defense has no further questions. De la Rionda begins redirect.
