A published report says the jury in the case of Zacarias Moussaoui came within one vote of sentencing him to death for his role in the September 11, 2001 terrorist attacks in the United States.
The foreman of the 12-member panel told The Washington Post that the lone holdout against the death penalty never explained his or her reasons, which frustrated the other jurors. The identity of the juror was not revealed because the vote was taken by secret ballot.
The jury had to reach a unanimous verdict in order to sentence Moussaoui to death.
After seven days of deliberation, the jury sentenced the 37-year-old Frenchman to life in prison without the possibility of parole last week.
Moussaoui is the only person in the United States to be convicted in connection with the September 11, 2001 terrorist attacks. He pleaded guilty to six counts of conspiracy last year.
