A New York real estate executive accused of trying to flee to South America while charged with vehicular homicide and drunken driving has been ordered held without bail.

Sean Ludwick appeared before a judge Tuesday in Central Islip (EYE'-slihp) on Long Island.

Ludwick, a managing partner and founder of Blackhouse Development, previously pleaded not guilty in connection with the August death of his passenger in the town of Southampton.

Prosecutors said last week he had made inquiries while visiting Puerto Rico about buying a vessel capable of taking him to South America.

Prosecutors say an FBI agent moonlighting as a sailing instructor was among those who became suspicious.
