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

Attorneys for the boy’s parents, Jason and Elizabeth Derkosh, issued a joint statement Monday with the Pittsburgh Zoo & PPG Aquarium.

“Details of the settlement will remain confidential. The Derkosh family and the zoo request that the privacy of all parties involved be respected,” the statement said.

The couple’s son, Maddox, lunged from his mother’s grasp and fell some 10 feet from the top of 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 Derkoshes sued in May 2013, and the zoo countered in September by arguing his mother was to blame for his death, because she lifted him atop the 4-foot-tall wooden railing.
