Dozens of cars were damaged in Massachusetts and New Hampshire over the weekend after someone shot at windows with a BB gun, police said. Investigators were looking for the suspect who they said blew out more than 65 car windows in Nashua, NH and in nearby Hooksett, NH Friday night. Officials said that the incident involved a dark-colored vehicle with spoiler and a loud exhaust. Damage stretched from Daniel Webster Highway all the way to the Merrimack line on Amherst Street and various other locations around the city.
