ST. LOUIS (KTRS) The administration at MICDS, the prestigious college prep school that yesterday expelled five students who exchanged a series of racist, profane and sexual Snapchat messages, is investigating a message board threat against the school. Ladue Police are assisting with the school’s investigation of the post that included quotes from the film, Fight Club, threatening the Upper School administration. The specific message board on which the threat was posted was not named. In a text to families Friday, the school says Ladue Police are investigating the threat and are on the campus this afternoon. Otherwise, the school says it’s following normal carpool procedures Friday afternoon.

In the Snapchat messages, at least three different people used an offensive racial slur against African-Americans.
