There has been a string of vandalism that involves rocks and BB guns in the Niagara Falls area recently. There is a possibility that these incidents are related to the recent thefts as well.

Niagara Falls police say that:

...three boys reportedly damaged cars in the Porter Road Hyde Park Boulevard area. Police think they could be connected to thefts from vehicles and other vandalisms. Cops are looking for three boys, two white and one black, ranging in age from eleven to 15-years-old.

It was just a few weeks ago that Channel 2 reported that two students admitted to carrying BB guns with them to school. The gun was tossed and recovered by the police before any damage or injury occurred.
