... Also, if the screaming voice was Z's, he'd have a broken nose at this point which would also alter his voice. ... The physical injuries seem to back Z screaming for that length of time.
Now that you are putting it as you do, I'm wondering, with a broken nose and assuming blood is draining down the back of his throat, would GZ really be able to project his voice enough to be heard in the background as it is --- so loud, sustained, and strong?
I keep going back and forth on the voice (whether it's GZs or TMs) myself and apparently GZs exemplar sheds no new light on it either, unless I'm mistaken re the results.
At any rate, I happened to stumble upon the following audio of the part of the 911 call from which the screaming and gunshot are both heard and thought I would post it here for any audio experts (which I'm not) to weigh in on it (below). The person who worked on the audio feels a scream can be heard just seconds after the shot. Now I thought all such pertinent extraneous sounds had been identified, i.e., a witness thought there was more than one gunshot -- it turned out to be a screen door slamming type of thing? I'm not so sure the "scream" is a screen door, however, but maybe it is or there is some other explanation for it. I also don't remember GZ referring to a "scream" after the shot. (Long) before this, it seems to me I could hear it when listening to the regular call because whatever I thought I'd heard (& it's a very vague memory, might not even be the same sound), I thought was coming from the home of the caller; I could be wrong about that though. Anyway, here is the link and the caption; the gunshot is at 1:09 and the "scream" is around 1:12. Perhaps some of you already know about this audio OR what the police attributed as the source of the "scream"? :

: "911 calls of altercation in background between George Zimmerman and Trayvon Martin. This audio was compressed, and runs at just a .o1 of a tenth over half speed. It's pitch however is 100 percent true to the original."
