O'Mara asked, "Do you stand by that today and what you saw was a 'ground-and-pound' event?"

[Updated at 11:23 a.m. ET]
Good said that no matter what statement he gave police, he has always said the person wearing red (Zimmerman was wearing a similar color) was on the bottom.

Good said he thought the person on the bottom was yelling for help.
[Updated at 10:20 a.m. ET]
O'Mara asked Good to define "ground and pound."
"It's usually when someone is on top in a mounted position I believe. In the dominant position, but like I said, the person on the bottom is able to throw punches back, but I did not see any of that," said Good.
[Updated at 10:17 a.m. ET]
O'Mara asked Good if the person on top was in a mixed martial arts stance. Good said at first he thought it was what he calls a "ground and pound."

"I just heard a shot right behind my house," said Good on the 911 call. "They are wrestling right in the back of my porch."
The operator asked, "You just heard one shot go off?"
"It was either that or a rock that hit the window," said Good.
[Updated at 9:50 a.m. ET]
At some point, Good told the people struggling on the ground to "cut it out."
[Updated at 9:49 a.m. ET]
Good said it was possible that the person on top may have been trying to hold the person on the bottom down.
[Updated at 9:47 a.m. ET]
"I think at that time is when I thought it was serious," said Good. "Because it looked like strikes were being thrown or punches being thrown. But as I clarified due to the lighting, it could've also been holding down. But there were arm movements going downward," he said.
[Updated at 9:44 a.m. ET]
Good said he only saw a "few" seconds of the altercation.
[Updated at 9:42 a.m. ET]
At some point, he could tell there were two people on the ground. He could only see the color of the clothing the men were wearing. He saw the men's position change.
[Updated at 9:39 a.m. ET]
"It looked like a tussle. I could really only see one person, and I think I described as possibly being some kind of dog attack, because there are a lot dogs that walk in that back area. I could only see an object," said Good.
[Updated at 9:37 a.m. ET]
Good's wife told him to not go outside, but he decided to out anyway.
