Cheon had appropriated roughly 40 million won ($34,200) from three women he had met through an online chatting site in 2011.

The women, all in their forties, did not suspect anything when Cheon lied to them about his age, saying he was 10 years younger than he really was.

Cheon deceived the women by saying that he graduated from Harvard University and worked as a professional interpreter.

He told each of the woman that he had invested 1 billion won on a Hollywood film and that he would bring the women to the United States after marriage.

Contrary to his fictional identity, Cheon spoke not a word of English, had never gone to university and was jobless.

The victims reported him to the legal authorities, finally leading to his arrest four years later.

The police said Cheon had attractive looks and smooth conversational skills.

Based on how Cheon led an active social life, the police assumed there could be more victims of his misdeeds.
