Authorities are searching for a hit-and-run driver whose car struck and injured a 13-year-old girl who was shoveling snow away from her family’s mailbox in Leeds. The Androscoggin County Sheriff’s Department says in a statement released early Tuesday that the girl suffered non-life threatening injuries Monday afternoon. Investigators are seeking help from the public in locating the driver and vehicle involved in the crash. They describe the car as a blue smart car that was last seen driving west on Church Hill road toward the town of Turner. The vehicle should have some noticeable damage on the passenger side after hitting the girl and the mailbox.
