BOSTON AP – Lawyers for the man who calls himself Clark Rockefeller are asking a judge to suppress statements he made to investigators after he was arrested in Baltimore in the kidnapping of his 7-year-old daughter.

Rockefeller, whose real name is Christian Karl Gerhartsreiter, claims he told investigators 14 minutes into a 4-hour interrogation that he didn’t want to talk. In a motion filed Monday in Suffolk Superior Court, Gerhartsreiter says the statements he made should be thrown out because he invoked his right to remain silent.
