The tragedy at the San Francisco Zoo is being investigated in depth to determine whether a tiger escaped because of negligence or equipment failure or whether it was provoked to jump an 18-foot wall.

“Investigators are seeking witnesses and intend to interview the survivors, two brothers ages 19 and 23, who were in shock but in stable condition after surgery to clean wounds from “deep claw and tooth attacks,” said a doctor at a news conference at San Francisco General Hospital. The identity of the brothers has not been released.”

“The tiger, a 300-pound female Siberian named Tatiana who attacked a zookeeper last December, was shot to death by the police after the zoo’s 5 p.m. closing on Tuesday, after it somehow jumped barriers around the Lion House habitat and killed Carlos Sousa Jr., 17, of San Jose.”
