CINCINNATI -- A federal inspection has concluded that the Cincinnati Zoo's barrier to keep the public and gorillas separate wasn't in compliance with standards for housing primates the day a 3-year-old boy slipped into the gorilla exhibit and a gorilla named Harambe was fatally shot.

The inspection report states that the zoo's dangerous-animal response team properly followed procedures after zoo visitors called 911 on May 28 to report a child in the gorilla enclosure. A team member concluded the child was in "life-threatening danger." The gorilla was killed to save the boy's life.
