A fire at a playground in Lexington that caused close to $100,000 worth of damages on Tuesday is being investigated. Lexington Police believe the fire was started by juveniles who were playing with fireworks, which set the wooden play structure at Morton Elementary School ablaze. The equiptment, which had been installed just last summer, is considered a total loss. Because of the amount of damage that occurred, criminal mischief charges could potentially be filed against those responsible for the fire.
