The story continues to develop, the dead teen may turn out to be the hero of this story.

Police in California say the man killed by a tiger in a San Francisco zoo on Christmas Day may have died trying to save his friend's life.
Police say Carlos Sousa, 17, shouted in an attempt to distract the 300lb (136kg) tiger Tatiana as it clawed his friend Kulbir Dhaliwal.
The animal then killed Mr Sousa with a slash across his throat, allowing Kulbir and his brother Paul to escape.

I also wanted to add an unrelated news story that has a sad note.

Two Siberian tiger cubs have been found dead in a refrigerator at a Chinese zoo less than a week after another incident involving the endangered
species.
They were found in a ticketing office at a wildlife park in China's central Hubei province.
Tiger body parts are treasured as medicines in China.
On Thursday a female Siberian tiger was found dead in the same area. Thieves had broken into its cage, tranquillised the animal, then butchered it.
That tiger's remains were found by zoo keepers.
It had been beheaded and skinned, and its legs had been removed.
Only an estimated 400 Siberian tigers still remain in the wild.

Goodbye tigers, it's been nice knowing you.
