Two days before 9/11, a hotel owner in Deerfield Beach, Florida, finds a box cutter left in a hotel room used by Marwan Alshehhi and two unidentified men.

A bag hijackers Alhazmi and Almihdhar left at a mosque in Laurel, Maryland, is found on September 12. The bag contains flight logs and even receipts from flight schools from San Diego the year before (see September 9, 2001).
The hijackers past whereabouts can even be tracked by their pizza purchases. An expert points out: “Most people pay cash for pizza. These [hijackers] paid with a credit card. That was an odd thing.” [San Diego Union-Tribune, 9/3/2002] “In the end, they left a curiously obvious trail—from martial arts manuals, maps, a Koran, Internet and credit card fingerprints. Maybe they were sloppy, maybe they did not care, maybe it was a gesture of contempt of a culture they considered weak and corrupt.” [Miami Herald, 9/22/2001] Note The New Yorker’s quote of a former high-level intelligence official: “Whatever trail was left was left deliberately—for the FBI to chase” (see Late September 2001).
