BOSTON (AP) – Lawyers for a German man who calls himself Clark Rockefeller say they’ll appeal his kidnapping conviction, calling it “the first chapter” in the case.

Attorney Jeffrey Denner told “The Early Show” on CBS on Saturday that he’s also considering filing a motion for a new trial, though he declined to say on what grounds.

Rockefeller’s real name is Christian Karl Gerhartsreiter. He assumed various identities after coming to the U.S. three decades ago.

He was convicted Friday of snatching his daughter from a Boston street during a supervised visit last July, then fleeing to Baltimore with her.

Rockefeller is also considered a person of interest in the 1985 disappearance of a California couple. A grand jury is investigating that case.
