NEW ORLEANS, LA - AUGUST 29:  Jo Ann Foster leans against a Mausoleum as she pays her respects at the New Orleans Katrina Memorial where nearly 100 unclaimed or unidentified victims of Hurricane Katrina are interred as she attends an event to remember the 10th anniversary of Hurricane Katrina on August 29, 2015 in New Orleans, Louisiana. Jo Ann said, 'she was leaning against the wall and talking to the souls that are gone, the people that were floating and to the dancers that disappeared'.
