Blues center Mike Danton is back in the St. Louis area after extradition this weekend. Today he’ll have an arraignment in an Illinois courtroom, where he’s expected to plead not guilty to charges that he set up a plot to murder his agent, David Frost. Danton was arrested in San Jose, California on April 16, soon after the Blues were eliminated by the Sharks in round one of the Western Conference playoffs. He stayed there until returning to the St. Louis area yesterday.
