A young white rhino was killed after being shot in the head three times by poachers who broke into the Thoiry Zoo in Paris Monday night. Poachers de-horned the 4-year-old rhino, named Vince, and left alive two other white rhinos, 37-year-old Gracie and 5-year-old Bruno. They left part of Vince's second horn, leading local police to believe they were ill-equipped or interrupted. The poachers are still at large.
