 On September 12, 2001, the Toyota Corolla purchased by Mihdhar was found in Dulles International Airport's hourly parking lot.Inside the vehicle, authorities found a letter written by Mohamed Atta, a hijacker aboard American Airlines Flight 11; maps of Washington, D.C. and New York City; a cashier's check made out to a Phoenix, Arizona flight school; four drawings of a Boeing 757 cockpit; a box cutter; and a page with notes and phone numbers, which contained evidence that led investigators to San Diego.On September 19, 2001, the Federal Deposit Insurance Corporation (FDIC) distributed a special alert that listed Mihdhar as still alive, and other reports began suggesting that a number of the alleged hijackers were likewise still alive.
