A Boston judge denied California authorities investigating the disappearance of a married couple access to the divorce record of the man who calls himself Clark Rockefeller.

Jeffrey Denner, an attorney for Rockefeller, said Family and Probate Court Judge E. Chouteau Merrill made the decision Wednesday during a closed hearing in Boston.

The German native, who authorities say is actually Christian Karl Gerhartsreiter is being held on charges he kidnapped his 7-year-old daughter last summer.

He's also been named a "person of interest" in the 1985 disappearance of a California couple.

An attorney for California authorities refused to comment after the hearing.
