No, nor is it a proven fact that the voice belonged to Martin. So all that can be ascertained from the voice is that one of the two was in hysterical distress.
So what other evidence is there? Well, we know that eyewitness accounts show that Martin was on top of Zimmerman beating him. We also have forensic evidence showing that Zimmerman was beaten. So from this evidence, it is reasonable to ascertain that the voice of distress belonged to Zimmerman. Capisce?
