It all began on January 13 when a clouded leopard named Nova went missing from her habitat. And although she was recovered within hours someone had cut the fence to let her out.
On January 21, an endangered vulture died and an unnatural death at the zoo.
More cameras were added to the facility. And despite the additional security measures more cages were tampered with.
Finally, the monkeys went missing. And were found miles away.
Police continue their investigation. The Dallas Zoo is offering a $25,000 reward for information about the strange incidents.
