Montecore the tiger apparently wasn't hungry. And there's no evidence that he was deliberately provoked, sprayed by a terrorist or unnerved by a woman's beehive hairdo.
Those are the conclusions in federal investigators' final report on the Bengal tiger's attack nearly two years ago on illusionist Roy Horn.
But the Agriculture Department says it still doesn't know what led the tiger to attack Horn during a Siegfried-and-Roy performance in Las Vegas.
Horn was left partially paralyzed after the 380-pound tiger sank its teeth into his neck and dragged him off stage.
The Agriculture Department closed the case late last year with no official determination of what set Montecore off.
However, investigators do say the Siegfried-and-Roy show failed to protect the audience, because there was no barrier separating the tiger from the crowd.
