Breaking news from St. Louis....

Fox News is reporting some breaking new out of St. Louis. Several people in two area emergency rooms have reported breathing a strange substance that has turned them blue and induced difficulty in breathing. The emergency rooms have been shut down and have gone into emergency mode. I can't find anything about this on the internet yet, not even Fox News has posted it at this time. I find this situation interesting since it is in the city in which my grad school is located and in one of my classes we are discussing emergency room disaster plans and responses to chemical/biological agents. So another interesting situation to watch....
