The Dallas Zoo is reopening part of a gorilla exhibit that has been closed for two years after one of the animals escaped and attacked three people.
The zoo spent more than $2 million to renovate the gorilla den. It now features higher walls topped with an electrified wire. Part of the exhibit opens Saturday, with the full exhibit open in June.
The renovations were necessary after a western lowland gorilla named Jabari jumped over 12-foot walls and bit a toddler and two others before police killed him.
Zoo officials say even with the improvements they cannot promise a gorilla will not escape again. The zoo's director says "We all think it was a fluke thing, but in this business, you expect the unexpected."
