A few Park city residents and businesses have been attacked with marbles.  Windows have been broken and a few bumps n bruises from passing people having marbles flung at them from moving cars.  Anyone coming forward with information leading to the arrest of the marble bandits will be given a $2,500  reward. These marble attacks have been going on since last fall, with approximately $20,000 worth of damage being done in several different instances.  Police figure the perp is using a slingshot or a paintball gun with marbles.
