I wonder if there are limitations on the voice ID witnesses the state can put on in rebuttal. I can see why they might be allowed to attempt to "even out" the score of voice witnesses, but it doesn't seem like it's, strictly speaking, rebuttal evidence. The issue was not first brought up in the defense case. The state presented Sybrina in their direct case almost exclusively to say it was TM screaming. They could have put on additional witnesses, had they chosen to do so. Presenting more voice ID witnesses is really a continuation of their direct case.
