(April 3, 2006)—Deliberations resumed Monday in Alexandria, Va. in the death penalty trial of Zacarias Moussaoui, the only person charged in the 9/11 attacks.

He has already confessed to being an al-Qaeda terrorist conspirator.

The jury must find him responsible for at least one death on 9/11 in order to consider whether he should be executed.

The jurors have deliberated for 12-and-a-half-hours since Wednesday.

George Washington University law professor Jonathan Turley says he's surprised deliberations have taken this long.

But he says there's controversy about Moussaoui's crime and whether it deserves the death penalty.
