A zoo shot and killed a 17-year-old gorilla that grabbed and dragged a four-year-old boy who fell into the gorilla exhibit moat on Saturday afternoon, the Cincinnati Zoo`s director said. Authorities said the boy, who fell 10 to 12 feet, is expected to recover after being picked up out of the moat and dragged by the 400-pound male, lowland gorilla named Harambe. The boy was in the moat for about 10 minutes and was in between the gorilla`s legs when the gorilla was shot, according to WLWT. While zoo officials are still investigating, they believe the boy crawled through a railing barrier, and then fell into the moat.
