(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.
