Per Alpha Phi's Facebook page, Kristy Irvine Ryan (Zeta Psi - Dayton) was in the WTC's South Tower when the plane hit. She graduated from Dayton in 1993 and worked as an equities trader for Sandler O'Neill & Partners on the 104th floor.

There's a nice story about her on Good Morning America's web site: Sept. 11 Victim Helped Poor on the Sly.
R.I.P., to her and all of the victims of the attacks, and to all of the brave men and women who have lost their lives in the ongoing wars.
