Amber Alert Off, Little Girl Still Missing

July 28, 2008— -- An Amber Alert triggered by the alleged Sunday afternoon kidnapping of a 7-year-old girl in Boston was called off today although the missing child has yet to be found.

The Boston Police Department has an arrest warrant out for Clark Rockefeller, the child's father, on charges of custodial kidnapping, assault and battery, and assault and battery with a dangerous weapon.

Boston police said the Amber Alert in Massachusetts for Reigh Rockefeller was called off because they believe her father, who is recently divorced from his wife, took their child across state lines into New York.

"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) evening," the Boston Police Department announced in an afternoon news release. "Detectives have also learned that Clark Rockefeller may be headed to Long Island to pick up his recently purchased boat known as 'Serenity.'"

Police said that although a social worker who was supervising the father's visit was shoved aside during the alleged abduction, authorities do not believe the girl is in any physical danger.

Frasier Seitel, a spokesman for the John D. Rockefeller family, told ABCNews.com that Clark Rockefeller, 48, is not a descendant of the wealthy industrialist family of New York. Boston police say the kidnapping suspect goes by several aliases, including J.P. Clark Rockefeller, James Frederick, Clark Mill Rockefeller and Michael Brown.

Rockefeller is a former board director of the Algonquin Club of Boston, a private dining club founded in 1888 that is just blocks from where the alleged kidnapping took place. Lassaad Riahi, the general manager at the Algonquin Club, told ABCNews.com that Rockefeller resigned his membership from the club three months ago "on his own terms."

One of Rockefeller's neighbors described Clark in an interview with the Boston Herald as "odd," but a doting father when he still lived in the neighborhood who often took care of the Reigh while his wife worked.

Boston police identified Rockefeller's ex-wife and mother of the child as Sandra Boss, a senior partner in the London office of McKinsey & Company. She has done consultant work for New York Sen. Charles Schumer and New York City Mayor Michael Bloomberg, and has ties to the Metropolitan Museum of Art in New York and the Museum of Fine Arts in Boston.
