A Waupaca man is returning to prison after being convicted of his 14th drunk driving offense. Sixty-four-year-old Daniel Nordell was given a six-year sentence during a Monday appearance in Waupaca County Circuit Court. Investigators say he was arrested after hitting a mailbox, a speed limit sign and a utility pole in Farmington last May. His blood alcohol content was measured at more than double the legal limit. Nordell received a three-year sentence for the same crime in 2006.
