In an interview with CNN she recounted the moments after the bombing, she said "A woman, as if she heard my thoughts, turned to me and grabbed my hand and said, 'I am Joan from California, and I am not going to let you go.'"
That woman used her belt as tourniquet and saved her life. She never got to thank her, so lets see if the power of the internet can find this woman.
If you know who Joan is email email@example.com
