A pedestrian who was hit and killed by an SUV in Sonoma Valley is being identified as a man from Napa. Early Wednesday morning, 29-year-old Querubin Hernandez-Gutierrez was standing near a tractor on the shoulder of Arnold Drive, just north of Olive Avenue. He was talking to the tractor operator when a Ford Explorer drifted into the shoulder of the road hitting the back of the trailer being carried by the tractor before hitting Hernandez-Gutierrez. He died of his injuries while the Ford and Tractor drivers suffered minor injuries. The Ford driver is not suspected of intoxicated driving and hasn’t been arrested. It’s still unclear why his vehicle drifted onto the shoulder.
