A Manhattan real estate developer charged with driving drunk when he crashed his Porsche, killing his passenger, was ordered jailed Monday on bail of $500,000 cash, $1 million bond.

Sean Ludwick, 42, was arraigned at Southampton Town Justice Court on charges of driving while intoxicated and leaving the scene of an accident involving a fatality.

Judge Deborah Kooperstein granted the prosecutors' request for bail.

Ludwick crashed his car shortly before 2 a.m. Sunday, hitting a utility pole on Rolling Hill Court East and Highview Drive in Sag Harbor.

His passenger, Paul Hansen, 53, of Sag Harbor, was pronounced dead at the scene, police said. He was a real estate agent with Douglas Elliman in Sag Harbor, the company said.

Police said they found Ludwick minutes after the accident, some distance away, standing unsteadily outside his car.

Ludwick's attorney, Daniel Ollen of Manhattan, said the prosecution's bail request was "excessive in the extreme," and said bail should be set to reflect the low-level felony and single misdemeanor, "not charges that might happen in the future."

Prosecutors said nothing about additional charges, but the results of a blood test had not been returned early Monday.

Ollen said he expected his client would be able to post bail.

He called Ludwick "a major real estate developer in the United States and across the world."

Ludwick owns residences in Bridgehampton and Manhattan, Ollen said, and operates his business out of the Manhattan address. Reports said Ludwick is the founder of BlackHouse Development.

Police said Ludwick lives in Sag Harbor. Court papers show his Manhattan address to be 31 Sutton Pl.

His wife was in the courtroom Monday but did not speak to the media.

Robert Hansen, 60, of Southampton, the victim's brother, called him a wonderful father. "He was a wonderful provider for his wife and family."

When police found Ludwick, there was a strong odor of alcoholic beverage was on his breath and his speech was slurred, court papers said. He swayed and stumbled when he was interviewed by police and asked to speak to his attorney, according to the court papers.

Ludwick refused a breath-analyzer test but police received an order to draw blood. He was tested at 5:50 a.m., about four hours after the crash, the documents said.

Southampton Town police ask anyone with knowledge of the crash to call the detective squad at 631-702-2230 or Crime Stoppers at 800-220-8477. All calls will be kept confidential.
