Authorities say a New York City real estate executive facing vehicular homicide and drunken driving charges over a fatal crash in the Hamptons tried to flee to South America.

A spokesman for the Suffolk County district attorney says Sean Ludwick was apprehended by federal authorities in Puerto Rico. The spokesman, Robert Clifford, says Ludwick was trying to buy a boat large enough to take him to South America.

Ludwick was free on $1 million bond after being indicted in the August death of a passenger in the town of Southampton.

After his capture in Puerto Rico, he was brought back to Long Island and ordered held without bail Wednesday. His attorney declined to comment.
