Mr. Kennedy, an independent presidential candidate, confessed to dropping off the bear cub 10 years ago and making it appear that a bike had hit the animal.

Robert F. Kennedy Jr., the independent presidential candidate, confessed on Sunday that he had left a dead bear cub in Central Park in Manhattan in 2014 because he thought it would be “amusing.”

Mr. Kennedy posted a video detailing the bizarre story on social media apparently ahead of an article in The New Yorker.
