I've been listening to the coverage for the last 15 minutes or so and heard that too.From what I've heard,I think that means that no attempt was made to make the jury "death certified" which,I think,would be required if the state was seeking the death penalty.
My sense is that that's all it means.
THe State was barred from seeking the Death Penalty because the original jury sentenced her to Life, and no new evidence was presented in this case. So, there was no need to ask the 'SUPPORT" question since there was no possibility of a Death Penalty sentence.
A capital murder conviction in Texas carries either life in prison or the death penalty. Prosecutors could not seek death this time because the first trial's jurors sentenced her to life in prison, and authorities found no new evidence.
