New developments in the deadly tiger attack at the San Francisco Zoo on Christmas day.
Police are now investigating whether one or more of the victims in the mauling may have somehow provoked the animal.
The 350-pound tiger leaped out of its enclosure, mauling one man to death, and severely injuring two others.
Those two men are currently in the hospital.
"they're being held and will not be released today," said Dr. William Schecter, of the San Francisco General Hospital.
Evidence shows the victims possibly provoked the tiger to jump 25 -feet over a wall and the moat.
Other evidence includes a footprint found on a metal fence, suggesting someone may have tried to get closer to the tiger
