I don’t have the specific links, but various anons say they have tracked down news stories that link this story to a real case which occurred in Chicago in 2003. Here is a discussion on the subject seen on /cgl/ in September 2013 (IE: today!)
The first incident took place at somewhere called “Anicon”, but there’s several Anicon conventions (one in Hong Kong, one in Buenos Aires and one in, presumably, the USA, though I don’t know where. But somewhere in IL would be a decent bet).
