BOSTON -- The man charged with kidnapping his daughter, who the FBI says masqueraded as a Rockefeller for years, said he met his wealthy wife in New York when the couple's church group got together to play a live version of the board game "Clue."

Christian Gerhartsreiter, currently held in the Suffolk County Jail on charges he kidnapped his daughter Reigh Boss, 7, in July, and assaulted a social worker in the progress, said in an interview with NBC News that he met the girl's mother, Sandra Lynn Boss, when she came to his Manhattan apartment to play "Clue," acting the part of Miss Scarlett. He said he often portrayed Professor Plum.

He said there was "No doubt," that it was love at first sight.

Gerhartsreiter, who eventually married Boss in a Quaker ceremony on Nantucket, went by the name Clark Rockefeller during the couple's 13-year marriage, but the FBI now says fingerprints show he is really a German national who came to the U.S. as an exchange student in the late 1970s and who California authorities want to question in connection with the disappearance of a San Marino couple in 1985.

Gerhartsreiter said he had not planned to take his daughter from her mother during a supervised visit in Boston on July 27, nor did he plan to go into hiding in Baltimore, where he was eventually arrested.

"That's perhaps an extreme way of saying it," Gerhartsreiter said. "I wanted to change my life. I could no longer afford to live in Boston."

He said he and his daughter, "Had a wonderful time together, first in Boston and then in Baltimore. We had six days of intense fun."

Asked why he would take the young girl away from her mother, with whom she'd been living in London since her parents divorced at the end of 2007, Gerhartsreiter said, "She had been taken away from me for eight months -- very cruel months."

He acknowledged that he and Boss were known as a golden couple who entertained lavishly during their marriage.

"Stilton (cheese) and sherry were part of our trademarks," he said, and the vintage cars they owned "were bought inexpensively, for next to nothing."

His attorney said the couple lived well because Boss earned more than $1 million a year.

"She was the breadwinner and he was the caretaker," Steven Hrones said.

Gerhartsreiter continues to insist that his name is Rockefeller and that it was given to him by "someone he looked up to." Asked if he thinks he really is a Rockefeller he said, "I really couldn't tell you, maybe we can do a DNA test sometime."

"I have no doubt it was my name," he said.

He said the issue of his identity and name "never came up," with his wife.

"He's not denying that he might be this person, he just doesn't remember," Hrones said.

He claimed to have worked as a research assistant for people who worked for both NASA and the Pentagon, but was not successful in his pursuit of a theatrical career.

"Acting I did not get very far," he said.
