At his arraignment, Ryan Rubenzer stood mute to charges of homicide by intoxicated use of a vehicle. Not guilty pleas were entered by Judge Thomas Sazama.
The district attorney's office added two additional charges of homicide by vehicle with the use of a controlled substance, saying blood tests from Rubenzer detected marijuana.
In May, Rubenzer was driving a car that crashed southeast of bloomer, killing 20-year-old Kelly Hartman and 19-year-old Adam Ludwigson.
A trial has been set for February of next year.
