(Minneapolis, MN)  --  A Long Lake man faces federal charges for mailing a suspicious white powder to Dow Jones and Company last May.  The indictment alleges 69-year-old Richard Kozak sent an obscene note and a quantity of a white powder in response to a magazine offer he received.  The Dow Jones mail facility in Massachussetts was evacuated and a haz-mat team was called in to determine if the powder was anthrax or posed a biological threat.  It was later found to be baking flour.  If convicted, Kozak could be sentenced to a maximum of five years in federal prison.
