 This is the Publix Radio. Good afternoon. I'm Dave Fallon in Providence. Area authorities are searching for the driver of a tractor-trailer rig who they say left the scene of a fatal Monday night accident in Smithfield. Smithfield police say that 25-year-old Aliana Ciacciarelli was struck by the truck after she fell off a bicycle. This happened on Pleasant View Avenue at about 9.30 last evening.
