Mr. Mollinedo [the zoo director] said that he had not seen a police report about Tuesday’s events but that he believed, in part based on a discussion with a crime site investigator, that there was blood outside the animal exhibit and blood spots were seen along one of the walkways near a trail leading to the cafe, where the injured brothers were found.
From the Houston Chronicle article (your 4th link):
The minimal evidence found at the scene included a shoe and blood in the 25-foot-wide moat that surrounds the tigers' grotto, raising questions about what role, if any, the victims might have had in accidentally helping the animal escape.
Police sources said a footprint had been found on a metal fence, suggesting that someone had climbed it to get closer to the big cats.
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.
