Story highlights 'Simon' is the son of the largest rabbits in the world

"I haven't got a clue who's to blame," the breeder says

(CNN) United Airlines has taken another blow to its image after a giant, apparently healthy rabbit died following a intercontinental flight.

The bunny was found dead at Chicago's O'Hare International Airport, the same place passenger David Dao was dragged off a United flight earlier this month -- dragging United's reputation through the mud.

It happened when Simon, a 3-foot-long, 10-month-old Continental Giant rabbit, flew in from London's Heathrow Airport to O'Hare on April 19.

"I haven't got a clue who's to blame, but it's certainly very weird when Simon was so healthy," said Annette Edwards, a breeder who sold the bunny.
