A driver struck and killed a 7-year-old victim on Main Street near the village center of Williamstown last Friday afternoon. The District Attorney’s office alleges that the suspected perpetrator was driving east on Main Street, towards the town center, while the victim was traveling on a bicycle down Buxton Hill Road toward Main Street. Williamstown is a rural town in the northwestern corner of Massachusetts, and the home to Williams College, whose campus lines both sides of Main Street through the center of the town. Much of Main Street in Williamstown is also part of Massachusetts State Route 2, the main east-west highway through northwestern Massachusetts. There are no sidewalks on that part of Main Street, and it was on that segment where Friday’s killing occurred.
