The situation with regard to information about what really happened could best be described as "fluid" at this point.
From a variety of news sources:
- The moat wall was only 12.5 feet high, not 20 ft high as the zoo officials previously stated. Zoo experts are quoted as recommending a minimum of 16 feet for moat depth for big cat enclosures.
- The two brothers, aged 19 and 23, who were the survivors of the attack, and are recovering from their wounds, have been described by one source as not fully cooperating with the police investigation of the incident. They have prior arrest records for disorderly conduct and resisting arrest type offenses.
- A foot print was found on the waist high fence railing around the enclosure. Police are deterimining if it matches any of the shoes of the victims.
- The cat first attacked one of the survivors. When he yelled, it let him go and attacked Sousa. When the others saw him get killed by the tiger, they ran to the cafe about 300 ft away where they figured there would be others who could help them. The tiger then followed them, perhaps tracking their trail of blood, to corner them in front of the cafe. When police arrived, the tiger resumed attacking one of the men, at which point the police either distracted the tiger with their squad car lights, or advanced en masse on the tiger. When it turned towards them and approached, they shot it multiple times with their 40 calibre service revolvers.
- The zoo staff is equipped with rifles etc. to handle such emergencies but the police arrived - in about 20 minutes - before those weapons could be deployed.
- SF Police Chief Heather Fong says there is no indication from the investigation at this time that there was any taunting of the animal or trespass into its enclosure - at this time.
- One source states that bits of concrete were found in the tiger's hind paws, indicating it had scaled the moat wall.
