But I wasn't watching out the window during that. And then the next time I looked out the window, there same thing, two men on the grass, one on top of each other. I kind of felt like that I couldn't see a lot of movement, because 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.
COOPER: You say gunshots, plural. Was there more than one, to your memory, or was there just one?
UNIDENTIFIED WITNESS: Well, the sound that I had from where I was walking, it was more like a pop, and 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. ---
Could it have been the crack noise, followed by the gunshot, that they heard?
