BOSTON -- Authorities now say that the driver of the truck that struck and killed a 10-year-old girl who was riding her bike in Foxborough over the weekend was an off-duty police officer.

The driver of the truck that hit fourth-grader Rose Shatz on Saturday was Mansfield police Officer Aaron Fine, who was working for his family's landscaping company at the time.

Police said it appears Shatz turned her bike in front of the truck and Fine could not stop in time. Fine has not been charged.

Grief counselors will be on hand at the Burrell Elementary School Monday.

The school superintendent said Shatz had just exchanged an e-mail with her teacher about a project she wanted to start. It was called "people who change the world."
