A Sonoma County judge will decide whether a man who killed a motorcyclist in a DUI crash in September will go to trial. Santa Rosa resident Charles Bernhardy appeared in court last week and his next pre-trial hearing is set for April 18th. On September 6th, Bernhardy struck a motorcyclist while driving on Fountaingrove Parkway. He failed to stop and continued driving with the motorcycle lodged underneath his truck for another two miles. The motorcyclist, 23-year-old Vance Stammer, died about two weeks later after being removed from life support.
