(Kennewick, WA) -- The suspect accused in a triple-fatal accident in Richland last weekend pleaded not guilty on three counts of Vehicular Homicide in Benton-Franklin County Superior court on Thursday. She's due back in court in April, with an expected jury trial set to begin in late May. Police say 19-year-old Jennifer Duong was behind the wheel of a car that crashed into a light pole off George Washington Way around 2:45am Sunday. The crash killed 3 passengers instantly, with two found inside the car, and another found on the street, apparently ejected from the vehicle. Court documents state Duong had admitted to drinking earlier. Authorities found the passenger side of the vehicle wrapped around the light pole, with the driver's side discovered about 130 feet away.
