This question likely refers to the high-profile 2023 incident at the Dallas Zoo, where two emperor tamarin monkeys were stolen after their enclosure was intentionally cut open. While those specific monkeys were recovered safely within 24 hours, the event was part of a series of suspicious incidents at that location. As of March 1, 2026, there have been no major reports of "missing monkeys" from prominent global zoos in the last 48 hours. However, the 2023 Dallas incident led to a nationwide overhaul of zoo security protocols, including the installation of high-tech infrared cameras and 24/7 "anti-tamper" monitoring systems for primate habitats. If you are hearing rumors of missing animals currently, it may be a local story or a drill. The Dallas Zoo remains the most famous historical example of such a theft, serving as a cautionary tale for modern zoological security and the protection of endangered or rare animal species in captivity.
