FOXBOROUGH, Mass. -- An off-duty police officer who was driving a truck that struck and killed a 10-year-old girl who was riding her bike in Foxborough over the weekend will faces charges, officials said Monday.

Mansfield police Officer Aaron Fine was driving the truck that hit fourth-grader Rose Shatz on Saturday on Willow Street. Fine, 33, was working for his family's landscaping company at the time of the accident.

On Monday, Norfolk District Attorney William R. Keating's office said that Fine was cited for driving a Class B vehicle without a Class B license. There is a criminal penalty associated with the citation. Officials also said the truck's load was overweight.

"We told the students that it was an accident and accidents happen and it was nobody's fault," said Foxborough Public Schools Superintendent Jan Norton.

Police said it appears that Rose turned her bike in front of the truck and Fine could not stop in time.

"It appeared that she turned abruptly in front of Mr. Fine's vehicle and unfortunately, the vehicle struck the young girl," said Foxborough Police Chief Edward Oleary.

Fine has been on the Mansfield police force for four and a half years.

"He is devastated by this. He is a parent and he is a good human being and his heart is broken," said Mansfield Police Chief Arthur O'Neill.

Grief counselors were on hand at the Burrell Elementary School Monday.

"Rose was a child who liked to do additional projects. She liked to read bigger books. She liked to perform. She was well liked," Norton said.

The school superintendent said Rose had just exchanged an e-mail with her teacher about a project she wanted to start. It was called "People Who Change the World."

The accident reconstruction team report will determine if Fine will face more charges, including motor vehicle homicide.

"If serious charges result, then we will have to take that into account. If not, then as soon as he is mentally able to come back to work, he will," said O'Neill.

Requesting privacy, the Shatz family declined to make a statement about the accident.
