Just two weeks before the 9/11 hijackers slammed into the Pentagon and World Trade Center, members of a Saudi family abruptly left their luxury home near Sarasota, leaving a brand new car in the driveway, a refrigerator full of food, fruit on the counter — and an open safe in the master bedroom.

In the weeks to follow, law enforcement agents not only discovered the home was visited by vehicles used by the hijackers, but phone calls were linked between the home and those who carried out the death flights — including leader Mohamed Atta — in discoveries never before revealed to the public.

Ten years after the deadliest attack of terrorism on U.S. soil, new information has emerged that shows the FBI found troubling ties between the hijackers and residents in the upscale community in southwest Florida, but the investigation wasn’t reported to Congress or mentioned in the 9/11 Commission Report.
