For weeks in early 2023, people were on high alert following a series of break-ins at the Dallas Zoo. Enclosures were tampered with, including the clouded leopard and langur monkey exhibits, and a lappet-faced vulture died from an apparent stab wound. Two emperor tamarin monkeys vanished and were later found at a boarded-up community home in Lancaster. The bizarre string of events captivated Dallasites until police arrested a 24-year-old man in connection with the crimes.
