Tatiana, a four-year-old Siberian tiger escaped her open-air enclosure by scaling a 12-foot-4-inch (or 3.8 meter) high wall at the San Francisco Zoo on Christmas Day, 2007, and mauled three men visiting the zoo, killing one of them.
17-year-old Carlos Souza of San Jose died after suffering blunt-force trauma from tiger bites to his head and neck. His friends, brothers Amritpal “Paul” Dhaliwal and Kulbir Dhaliwal sustained claw and bite injuries and were taken to hospital after the tiger was shot dead by police.
A year earlier, the same tiger attacked her keeper, Lori Komejan, at the San Francisco Zoo during feeding time, causing lacerations to the keeper’s arms. After the tiger escape, the zoo added glass panels to increase the height of the barrier around the big cat enclosure to exceed the nationally-accepted minimum standard of 16 feet 4 inches high.
