Rockmart Police Department officers were knocking on doors early Friday morning with bad news: several car windows were smashed in a spree of vandalism. The damage took place either late Thursday night or early Friday morning. The damage appeared to have been random. Cars were hit while parked on streets in front of homes. At least one damaged vehicle was parked almost directly beneath a security light. It made no difference. Among the neighborhoods hit was the Goodyear Village area of Rockmart.
