Is con-man "Clark Rockefeller" a murderer?

(CBS News) He was born Christopher Gerhartsreiter in Germany, but depending on the time and the place, he called himself Chris Crow, Christopher Chichester or Clark Rockefeller.

The Lifetime movie "Who is Clark Rockefeller?" depicted Gerhartsreiter's life of lies, from taking advantage of wealthy strangers to claiming royal lineage and to marrying a successful business consultant.

"He told me that his parents were George Rockefeller and Mary Roberts," said his former wife Sandra Boss.

The law finally caught up to him in 2008, when he was arrested for kidnapping his daughter during a bitter divorce and custody dispute. He was convicted in 2009 and is now serving four to five years in prison.

But in true Hollywood fashion, the story didn't end there and his arrest led investigators to dig up a cold case, the California murder of John Sohus in 1985.

The victim's body was chopped into pieces and buried in his backyard. Sohus and his wife lent their guest house to "Chris Chichester" for a time, and remember Chichester was really Gerhartsreiter.

Now, Gerhartsreiter is on trial for murder and the real question is whether the cunning con man is also a cold blooded killer.
