committed suicide? i think it was incredulous. i don t think he would have done it. reporter: still, it was another explanation and the jury would have to consider it. so now the courtroom waited and whispered. would harvey take the stand? i told the investigators that i thought he was going to testify. and they didn t think so. they thought i was crazy. what made you think he would? well, he s a con man and he likes to talk. and con men think they can talk themselves out of any situation. reporter: he was right. sure enough, harvey was confident, self-assured. had answers for almost everything. he didn t steal steven s money, he said. he came up with a story that no one had heard before his testimony. reporter: which was that steven actually owed him his entire inheritance to pay back a whole different loan. this second loan was verbal, said harvey, done on a handshake. undocumented, naturally.
