A red wallet belonging to victim Gennie Gambale, recovered from the rooftop of the Marriott Hotel at the World Trade Center.

Gennie Gambale was a vice president at Cantor Fitzgerald and was working on the 103rd floor of the North Tower when the first plane crashed into the lower floors, trapping those above. Her family put up thousands of posters around town in the hopes that she might be found alive, but it was in vain; she was 27 when she was killed. A police officer, who happened to be the mother of one of Gambale's friends, found Gambale's wallet on the roof of the nearby Marriott hotel and immediately recognized the name on the damaged cards inside, and ensured it was quickly handed over to the family.

Shoes worn by Florence Jones on Sept 11, 2001 as she escaped from the World Trade Center.

Florence Jones was still in her office at Baseline Financial on the South Tower's 77th floor when the second plane crashed into the building just one floor above. She and several colleagues tried two stairwells before finding their way to stairwell A, the only one not damaged by the crash. She took off her high-heeled shoes to hasten her descent - her boss carried them down for her. They were among the last to make it out of the tower before it collapsed.
