The Dunn County district attorney says she will seek a lengthy prison term for a man who has pleaded guilty to three counts of homicide by D-U-I.  Two weeks before he was to go to trial, Serghei Kundilovski admitted he had huffed the fumes from aerosol cans before driving the wrong way on Interstate 94 near Knapp.  Three men in another car were killed in the resulting head-on crash last July.  District Attorney Andrea Nodolf says she hopes there will be some justice for the victims’ families.  Sentencing is set for February 5th.
