The jury in the Zacarias Moussaoui trial resumed deliberations at 8:30 a.m. ET this morning. If they don't reach a decision by 4:30 p.m., they will resume again tomorrow.

The jury is NOT deliberating on whether Moussaoui should actually get the death penalty. Instead, it must answer: Is he eligible for it? To find that he is, jurors must conclude that Moussaoui:

-intentionally lied to the FBI when he was arrested in mid-August 2001;
-that he lied contemplating that lethal force would be used as a result;
-and that at least one person died in the 9-11 attacks as a direct result of his lies.

The jury must find each of those factors, and its verdict must be unanimous. As a technical matter, it will consider those three factors for each of the three death penalty counts to which he pleaded guilty. But if it answers yes to the three factors on ANY of the counts, then it finds him eligible.

If the jury answers no, then the trial is over, and he will automatically get life in prison. 

But if the jury finds him eligible for the death penalty, the trial moves into the second phase. After hearing another few weeks of evidence, the jury will then be asked to decide whether he should actually be sentenced to death.
