Officials said that Reigh Rockefeller was kidnapped by her father, Clark Rockefeller, during a supervised parental visit on Sunday. Boston Police are interviewing the operator of the SUV. His identity was not released.

An Amber Alert issued in Massachusetts was discontinued Monday morning when Boston police received credible information that Clark Rockefeller, along with his daughter had moved on to New York to pick up his boat "Serenity."

"The sailboat or yacht is named the Serenity, and there are 380 vessels with that name. We are checking with the marinas," New York City Police Commissioner Ray Kelly said.

"Clark Rockefeller, who was carrying his daughter, attempted to put his daughter down between two vehicles when a black SUV pulled up," Boston Police Department Superintendent Bruce Holloway said. "At that time, Rockefeller grabbed his daughter and jumped into the SUV, which was being operated by a white male driver."

Boston Police investigators received information that father and daughter may have been dropped off near Grand Central Station in New York City at approximately 7:30 p.m. Sunday.

Police have obtained an arrest warrant for Rockefeller, 48, of Boston, charging him with custodial kidnapping, assault and battery and assault and battery dangerous weapon.

The girl and her mother, Sandra Boss, 41, were staying at Boston's Four Seasons hotel after flying to Boston from London for the visit.

Clark Rockefeller is also known as J.P. Clark Rockefeller, James Frederick, Clark Mill Rockefeller and Michael Brown.

"He wants everything his own way. He is willing to lie, cheat, manipulate to get what he wants. He certainly does not like the fact that he no longer has joint custody of his child. That is a situation that is unacceptable to him, and he is going to change it," said James Fox, of Northeastern University. "When you have a child it is a lot more difficult to hide under the radar."

Clark Rockefeller was described in the Amber Alert as being a white male in his 50s, about 5 feet 6 inches tall and 170 pounds with thinning blond hair, and was last seen wearing khaki pants and a blue Izod shirt.

The girl has blond hair and blue eyes, is about 4 feet tall and weighs about 50 pounds. She was last seen wearing a pink and white sundress with red shoes.

"Her legal name is Reigh Storrow Boss. Again, she goes by the nickname of Snooks. Her mother calls her Snooks. She speaks with a English accent and wears glasses," Boston Police Department Deputy Thomas Lee said.
