I just read about this - the FBI is looking for help solving a murder case where the victim was found with two coded notes on him. They've been unable to crack the code, and now they're asking the public for help. Obviously if the FBI's experts can't figure it out my odds are pretty slim, but I thought it was an interesting situation nonetheless. Here's an article about the case with images of the two encrypted notes: http://www.fbi.gov/news/stories/2011/march/cryptanalysis_032911
