SCITUATE –– The two Scituate Middle School seventh graders who were charged with vandalizing the 19-year-old Pilgrim and Native American Village at Clayville Elementary School have been sanctioned by the town’s Juvenile Hearing Board, according to the police.

The boys must perform 15 hours of community service, write letters of apology to the school’s principal and to the children of Clayville Elementary School and pay $100 in restitution, which is the highest amount the Juvenile Hearing Board can order a child to pay, Deputy Police Chief Stephen B. Lang said Thursday. In addition, the boys are barred from going on the school’s property unless they are there for a specific event and they are accompanied by a mother, father or other adult, Lang said.

The two attended Clayville Elementary School when they were younger and one lives quite close to the school, Lang said. The kinds of events they could attend at the school would be a younger sibling’s play or graduation, if they have younger siblings, he said.

The police have not named the boys because they are juveniles.

In addition, the police are now investigating whether a third child was also involved in the vandalism of the village in late September, Lang said. They had suspected early on that more than two children were involved, according to Police Chief David M. Randall.

The school has been working to rebuild the villages in time for the annual Harvest Festival on Nov. 5.

The police originally learned about the two boys’ involvement with the vandalism when the district’s school resource officer began investigating the school principal’s complaint about damage to the village, Randall said. Students, including one who witnessed some of the vandalism, provided details to that officer, Sgt. Kevin Pendergast, that helped him determine who had vandalized the wooden structures, Randall said.

When the boys were first charged with the vandalism, Randall said their appearance before the Juvenile Hearing Board meant they would not go to Family Court. In order to appear before the Juvenile Hearing Board, the boys’ parents essentially admitted that the facts were substantial enough to show that their children played some part in what happened, Randall said.
