San Francisco police probe fatal zoo attack

Police shot and killed the tiger after it turned toward them as they attempted to divert its attention from one of the injured victims on the ground.
Zoo spokeswoman Lora LaMarca said zoo officials could not comment on how the tiger got out of its habitat, a grotto surrounded by a 15-foot (4.5 meter) moat and 20-foot (6 meter) wall.
"It is an ongoing police investigation and it is still being looked into," LaMarca said.
San Francisco`s medical examiner identified the victim of the fatal attack as Carlos Sousa Jr. (17), of San Jose, California. He was pronounced dead at the scene.
The two other victims, 19- and 23-year-old brothers from San Jose, were reported in stable condition at a San Francisco hospital.
The tiger attacked Sousa in front of its enclosure and the the brothers about 300 yards from it.
