The first report I accessed last night at the San Jose Mercury News showed pretty distinctly that the zoo employees were under extraordinary pressure not to talk to the press so that all info would have to be funneled through official channels. I think that is why the story has been so slow in getting out. (Click on tag "tiger attack" to see the previous post and link to SJMN report.
The secrecy might be a reaction to the legal decisions handed down after last year's mauling of a zoo employee's arms.
But a San Fransisco Chronicle report "Trail of blood apparently led escaped tiger to victims " (at SF Gate.com) surmizes that at least one of the three friends was partially over the fence to the tiger enclosure, that they were all attacked together outside the cage, and that the two brothers fled to the cafe 300 yards away, with the tiger following their trail of blood.
Police sources said a footprint had been found on a metal fence, suggesting that someone had climbed the fence to get closer to the big cats. Authorities were looking into whether the tiger escaped by latching on to a leg or body part.
Zoo director Manuel Mollinedo said it was also likely that the animal was provoked.
"Somebody created a situation that really agitated her and gave her some sort of a method to break out," Mollinedo said. "There is no possible way the cat could have made it out of there in a single leap. I would surmise that there was help.
"A couple of feet dangling over the edge could possibly have done it."
Sources said pinecones and sticks that were found in the moat might have been thrown at the animal. Those items could not have landed in the grotto naturally, they said.
Well at least the police know how to leak some decent information.
