New Orleans Case
I'm looking for a story that I was reading on either fanfiction.net or AO3 a couple years ago. I think it may be classified as an AU. John goes to Sam at Stanford because Dean is missing. Dean was investigating a case in New Orleans shortly after Hurricane Katrina. Sam was retracing his steps. I hope someone knows what I'm talking about or has read this, I never finished it but I really want to.
