"48 Hours" Looks At The Killing Of Two Brothers Thousands Of Miles Apart

(CBS)  Asked how credible he finds Nancy's memory blackout, Wong says, "Certainly it’s a convenient time to forget what happened next. But also, perhaps she did. The fear, the shock combined with several years of bad experience she may have blanked out."

Trudy Samra, Nancy’s close friend, believes the self defense story and remembers seeing suspicious injuries. "The first time she had a rib injury. And one time we had a girls' night here. Then she came in. And I said, 'Wow, what happened to you?' And she had a big, big blue eye."

Trudy says she doesn't know if those injuries were caused by Robert but she admits Nancy never told her that she was being abused, and Robert’s friends, like Carol Horton, don’t believe it.

"Knowing Rob as well as I did, it just wasn’t in his nature to do that or to be that," she says.

After 65 days, the mostly male jury took just eight hours to find Nancy guilty of murder. But even today not everyone is sure what to believe.

"Even now after the verdict, I don't feel I've found out what happened. Only two people know what happened. And one of them is dead," says Wong.

The other, Nancy, is now serving a life sentence in a Hong Kong prison. In 2006, Moriarty went there with Nancy's mother Jean; Moriarty was the only television journalist to visit since her incarceration. Nancy continues to insist that she acted in self defense.

Robert Kissel’s case may be closed, but back in Connecticut, the police face a much tougher task finding the killer of Andrew Kissel. He was murdered less than three years after his brother, Robert, was killed in Hong Kong.

Andrew’s attorney, Phil Russell, says he never imagined his client’s life would end this way. FBI investigator is also unsure who committed this murder.

With the murder just days before Andrew was about to plead guilty to fraud, it appeared that the killer could have been someone who feared that Andrew was trading information for a reduced prison sentence.

But Russell says there was nobody Andrew was going to rat out.

Perhaps the most bizarre murder theory was that Andrew himself hired a hit man. He would do almost anything to avoid prison, but if he committed suicide, his children could not collect his life insurance.

"He was terribly remorseful about what he did, about the effect that it would have on his wife and children," Russell says.

Asked if he thinks Andrew may have planned his own murder, Russell says, "It’s plausible."

But FBI agent Steven Garfinkel doesn't buy that theory. "He was a narcissist. He liked himself too much," he says.

Andrew’s penchant for grandiosity has clearly complicated this case. No one truly knows the extent of everything he had his hand in, nor what deals he had made or with whom. The Greenwich police say they’re not ruling out anything.

Until there’s an arrest in the case, Chief James Walters is reluctant to release many details. In his first television interview, Walters says he believes that Andrew’s estranged wife, Hayley, may have some useful information. "I will say that we have spoken with Hayley and that we'd like to speak to her again," Walters tells Moriarty.
