He described Lee as "a very obedient child, warm and soft-spoken - someone you'd take to instantly".
Mr Lee said: "Who'd have thought she'd turn into this woman who is so adept at spinning lie after lie?"
The first sign of trouble came not long after she married her first husband.
Mr Lee said: "At first, I was apprehensive about agreeing to her marriage because she was still so young.
"But I thought she had found her happiness, so I gave my blessings."
When Lee returned home one day to say she wanted to file for a divorce, Mr Lee thought the couple merely had a tiff.
"It was only when her father-in-law approached me that I found out she had cheated them of their money.
"My grand-daughter begged for my forgiveness and I told her I could not do anything unless her in-laws agreed to let the matter rest."
They did - because of their grandchildren. Mr Lee said: "They just told her to get a job and work to pay off the money."
The next thing he knew, she had "vanished".
He said: "We didn't keep in touch and I have not seen my great-grandchildren. I only found out about her misdeeds from the newspaper reports."
Mr Lee added that he did not even know Lee had remarried the first time, much less the next four.
But he is adamant about keeping her away from his life now.
"I won't help her. I don't want to know anything about her," he said.
"Whether she is alive or dead, it's not my problem any more."
