A man was found dead inside the wheel well of a passenger jet that arrived in New York on Christmas Eve from Jamaica, officials said.

Maintenance crews discovered the body late Wednesday, several hours after American Airlines flight 1190 landed at John F. Kennedy International Airport (search), said Dan Maynard, a spokesman for the Port Authority of New York and New Jersey (search). The flight had originated in Montego Bay, Jamaica.

The man was about 25 years old but his identity had not been determined, Maynard said Thursday.

It was not known whether the man boarded the plane in Jamaica or had been aboard an earlier flight on the same airplane, said Carlo Bertolini, an airline spokesman.
