Connie Labetti was working for Aon Corporation in 2001. Her office was on the 99th floor of the World Trade Center’s South Tower—the second to be hit on September 11, 2001.

As the attacks began, she fled the South Tower and made it out alive—with help from her boss, Ron Fazio. The only trace of Ron recovered at Ground Zero was a mangled credit card.
