Tatiana and Tony expressing affection.
UPDATE, 10 Aug 2008: Thanks to National Geographic TV's Explorer for using this image in their "ZOO TIGER ESCAPE" episode. It aired tonight, 8/10/2008, and I thought they did a great job of recreating the story. It airs again on 8/17/2008. Here's the overview:
"Until December 25th 2007, no animal had ever escaped and killed a visitor at an accredited U.S. zoo. The first animal to achieve this dubious distinction was a tiger. A mild Christmas day in San Francisco has turned into a bloody tragedy the likes of which have never been seen before. Two young men were mauled, one 17-year-old boy and one 4-year-old Siberian tigress lay dead. Experts explore what might have happened in hopes of improving how dangerous animals are kept in captivity."
UPDATE: Tatiana, pictured here, is the Siberian tiger making the recent news headlines. The latest (27 Dec 2007) seems to indicate that the wall was too short:
"Once the animal is out of its primary enclosure, it's pretty much shoot to kill," Tilson said. "You don't have a discussion - you kill it. A tranquilizer gun would take too long and you might miss."
The other Siberian pictured here is Tony:
"Tatiana was born in the Denver Zoo on June 27, 2003, and donated to San Francisco in December 2005 to mate with a male named Tony."
