4:03 p.m. ET: The judge has dismissed the jury to take up a matter outside of their presence.
3:59 p.m. ET: Lauer says she couldn't see anything and couldn't say who was yelling for help. The attorneys are at a sidebar.
3:56 p.m. ET: Lauer says her husband never went out to help because he couldn't find the knife.
"He never did find a knife because he doesn't know where they're at," she said as several people in the courtroom laughed. O'Mara tells her this is being broadcast on TV and she just embarrassed her husband publicly (more laughing). O'Mara has finished this questions.
3:53 p.m. ET: Zimmerman didn't seem angry or hot-headed, according to Lauer. She thought his involvement with neighborhood watch was to help further benefit the community, not that he was a vigilante.
3:52 p.m. ET: "Did you consider the screams to be life-threatening screams?" asked O'Mara.
"Yes," said Lauer.
He holds up the bloody photo of Zimmerman taken by an officer and asks if the screams could be coming from someone having that done to him. She says yes, it's possible.
The prosecution objected when O'Mara held up a bloody photo of the back of Zimmerman's head.
3:50 p.m. ET: Defense attorney O'Mara is going over the map with Lauer, asking her where street signs were located. She says that a bush would sometimes obstruct the address numbers on her home.
3:47 p.m. ET: Lauer isn't sure if the "I have a gun, take my gun" comment was made to a police officer. When an officer asked her to identify the man who was the shooter, she said she didn't want to go up to him so the officer took a picture on his phone and brought it to her.
"I said I didn't know who it was," said Lauer. "He didn't look the same, I just didn't recognize him."
3:42 p.m. ET: "It just sounded like they were desperate and whoever it was really needed help or wanted help," said Lauer. "The yells for help -- the voice was the same the whole time."
Lauer says she didn't hear, "You're going to die mother [expletive]" -- she's not saying it wasn't said.
3:40 p.m. ET: Lauer says she could hear the yelps and helps better in person than someone listening to the recording.
"It sounded like they were in our living room -- it was right there," said Lauer.
3:38 p.m. ET: The three-part exchange turned to scuffling, which turned to yelps, which then turned to helps, according to Lauer. She thinks there were a couple of yelps before she connected with 911.
3:36 p.m. ET: O'Mara brings a map to the witness stand and has Lauer point out where the couch, love seat and TV were located in her home. She says she first heard the noise at the T-intersection behind her home. It was a three-part exchange. She never heard anything like, "What're you following me for?" or "What're you talking about?"
3:33 p.m. ET: Lauer says again that the yelling stopped after the gunshot. The prosecutor has finished his direct examination and now defense attorney O'Mara has started his questions.
3:32 p.m. ET: Lauer says she was a board member of the Home Owner's Association. She says Zimmerman came to a few of the meetings and she knew him by sight. She knew the neighborhood watch program was starting up and that he was involved. She couldn't identify the yelling voice as Zimmerman's because she had never heard him yell like that in their meetings.
3:30 p.m. ET: Prosecutor de la Rionda is going over an aerial view of the neighborhood, pointing out the entrance and the different roads.
3:27 p.m. ET: Lauer and de la Rionda are going over more photos, this time images taken in the light, pointing out where Lauer's home was located.
3:23 p.m. ET: Prosecutor de la Rionda is having Lauer point out on a map where her house is located. He also shows her a picture of the lighting conditions that night -- she says it was darker than the photo, which looks lighted. He's also showing her other photos from that night, pointing out where her house is located.
3:20 p.m. ET: Lauer says she heard someone say at one point, "I have a gun, take my gun." It was said in a matter-of-fact way and she didn't hear a response. Martin's mother, Sybrina Fulton, has returned to the courtroom now that the 911 call has finished playing.
3:19 p.m. ET: Lauer says she never heard anyone say, "You're going to die tonight mother [expletive]." She believes she heard nothing else but "help" and "help me."
