A witness who asked not to be identified, even by gender, told CNN's Anderson Cooper about hearing voices outside in an area where neighborhood residents often walk their dogs and wondering, "Oh, my gosh, who's out there walking their dog in the rain?"
Then the witness heard a "very loud, predominant voice" and opened the window.
"I couldn't hear the words, but it was like, OK, this is not a regular conversation. This is someone aggressively, you know, yelling at someone."
The witness recalled seeing two men on the grass, one on top of the other.
"And at that point, not looking out the window, I heard the yell for help, one yell for help, and then I heard another ... excruciating type of yell," the witness said. "It didn't almost sound like 'help.' It just sounded so painful. But I wasn't watching out the window during that. And then the next time I looked out the window, there's the same thing: two men on the grass, one on top of each other. I couldn't see a lot of movement. It was very dark, but I felt like they were scuffling. And then I heard the gunshots, which, to me, were more like pops than they were like a bang."
The witness recalled hearing more than one shot. "It definitely was more than one pop noise, so I don't know if it was an echo or anything else. But it definitely made more than one pop."
Then one of the men, who appeared to be Hispanic, started walking toward the witness' vantage point, the witness said. Zimmerman is Hispanic.
"He didn't appear hurt or anything else," the witness said.
