Police believe that a fatal tiger attack at the San Francisco Zoo was in part prompted by the victims provoking the animal into escaping its enclosure and mauling them.
The victims say they did not taunt the tiger.
A former zoo worker filed a lawsuit saying the zoo ignored complaints about an emergency response to a 2006 tiger attack.
Police say one of the three victims was intoxicated and told another victim's father that they were standing atop a railing and yelling and waving at the tiger shortly before the Christmas Day attack. Police found a partial shoe print that matched Paul Dhaliwal's on top of the railing. Watch the video.
Zoo officials found blood and small objects inside the fenced-in area overlooking the tiger moat.
The victims' attorney said there was no taunting and that the zoo knew the enclosure was dangerous.
