A 19-year-old Milwaukee man faces charges of homicide by vehicle, second-degree reckless homicide and drug use.  When Fond du Lac County deputies arrived on the scene of an accident last April, they say they found a car engulfed in flames and a woman trapped inside.  Jonathan Vogel told deputies the person inside his car was Whitney Domer.  He said he tried to get Domer out of the car before it burst into flames.  A blood test found traces of pot.  The charges were filed this week and he made a court appearance Thursday.
