U.S. officials say the FBI questioned Berg in 2002 after a computer password Berg used in college turned up in the possession of Zacarias Moussaoui, the al Qaeda operative arrested shortly before Sept. 11 for his suspicious activity at a flight school in Minnesota.
The bureau had already dismissed the connection between Berg and Moussaoui as nothing more than a college student who had been careless about protecting his password.
But in the wake of Berg’s gruesome murder, it becomes a stranger-than-fiction coincidence — an American who inadvertently gave away his computer password to one suspected al Qaeda operative, Moussaoui, is later murdered by another notorious al Qaeda operative, Zarqawi.
