The parents of a 2-year-old boy who was mauled to death after falling into a wild African dogs exhibit have settled their lawsuit against the Pittsburgh zoo.

The attorneys for the boy's parents, Jason and Elizabeth Derkosh, issued a joint statement with the Pittsburgh Zoo & PPG Aquarium on Monday.

Their son, Maddox, lunged from his mother's grasp and fell some 10 feet past a wooden railing into an enclosed exhibit below in 2012. He had bounced off a net meant to catch falling debris and trash, then into the exhibit, where several dogs fatally attacked him.

The bespectacled boy, who had vision problems, became the only visitor in the zoo's 116-year history to die.

The statement says the settlement is confidential and that the family seeks privacy.
