A 14 year-old was killed earlier this week in North Rockland after colliding with a snow plow while riding a motorbike. Stony Point Police say the unidentified teen was riding the bike southbound at the intersection of North Liberty Drive and Wayne Avenue when he crashed into a privately-owned plow truck just before three in the afternoon on Tuesday. The victim was treated at the scene by Rockland Paramedics and Stony Point Ambulance Corp and then taken to Westchester Medical Center. He died the next day. Police say the truck driver remained on the scene and is cooperating with the investigation. No further information was available.
