Remains of 2 Sept. 11 Hijackers Identified "New York medical examiners using DNA samples have identified the remains of two of the 10 suicide hijackers who crashed jetliners into the World Trade Center on September 11, 2001, officials said Thursday. The FBI provided the medical examiners' office with DNA profiles of the 10 hijackers, said Ellen Barakove, a spokeswoman for the New York Medical Examiner's office. Examiners "a few days ago" matched two of the profiles to remains collected after the twin towers' collapse, she told CNN."
