Confessed September 11th conspirator Zacarias Moussaoui has been taken to a super-maximum security prison in Colorado to serve his life sentence.

U.S. officials say Moussaoui was moved late Friday from Alexandria, Virginia, and arrived early Saturday at the prison in Florence, Colorado.

The Colorado prison houses domestic terrorist Theodore Kaczynski, known as the "Unabomber," and Ramzi Yousef, architect of the 1993 World Trade Center bombing. Richard Reid, the failed "shoe-bomber" terrorist with whom Moussaoui tried to claim ties, is also there.

Moussaoui, a French citizen of Moroccan descent, was sentenced last week to life in prison for his role in the September 11, 2001, attacks.

He pled guilty to six terror conspiracy charges last year. He is expected to be in solitary confinement for 23 hours a day, and has no chance of parole.

He is appealing his sentence and also a judge's refusal of his request to withdraw his guilty plea and have a new trial.

The jury had determined that Moussaoui was eligible for the death penalty, and they had to choose between either sentencing the 37-year-old to death or life in prison.

The jury foreman told The Washington Post in a story published Friday that the panel came within one vote of sentencing him to death. The foreman said the anonymous holdout never explained his or her reasons to the rest of the panel.

Moussaoui is the only person in the United States brought to justice in connection with the September 11, 2001 attacks.
