The murder trial of Christian Karl Gerhartsreiter gets underway in a Los Angeles courtroom today.
If the name doesn't ring a bell, perhaps you know him by his most notorious alias: Clark Rockefeller.
Gerhartsreiter is a German con-man who masqueraded as a member of the wealthy Rockefeller clan; It was just one of many identities he's assumed. He was unmasked in 2008 when he was arrested for kidnapping his seven-year-old daughter and leading police on an international manhunt.
Gerhartsreiter now faces murder charges in the 1985 death of a San Marino man, a cold case that had puzzled authorities for over a decade. Writer Mark Seal tells the story of Christian Gerhartsreiter in his book , "The Man in the Rockefeller Suit."
