muldoon got to the door and looked out and saw that wu was lying on his back , his body already torn open by the big claw , and the raptor was jerking its head , tugging at wu 's intestines even though wu was still alive , still feebly reaching up with his hands to push the big head away , he was being eaten while he was still alive , and then ellie stopped screaming and started to run along the inside of the fence , and muldoon slammed the door shut , dizzy with horror .
