These are the chairs that are setup in the footprint of the old Alfred P. Murrah Federal building to represent each victim of the April 19th, 1995 bombing at the Oklahoma City National Memorial.  When you see all 168 of them, it really makes you think how tragic that day was.  Each chair has the name of one of the victims on it.  As you can see here, the main chair in the foreground of this shot is named after Katherine Louise Cregan.  Here is a little something about her from the memorial's website:

"Katherine Louise (Kathy) Cregan, 60, was a widow devoted to her three sons, William, Regis and Christopher, her two grandsons, Sean and Jonathan, and her three granddaughters, Rachel, Kari and Michelle. She was fond of telling friends how much she loved to spoil them. Her two dogs, Yorkshire terriers Max and Jason, also received a great deal of her attention. Cregan, 60, was born Nov. 15, 1934, in West Memphis, Ark. She was a longtime resident of Oklahoma City and a graduate of Classen High School. She worked as a claims representative for the Social Security Administration for 13 years. "
