Not a murderer but a rapist. He was an 18 year old from a wealthy family and was a jock. He was charged with the rape of two girls then fled the country and hung out at ski resorts until he finally surrendered in Switzerland 8 years later.

He was ultimately found guilty of one rape and plead guilty to the other and served 10 years in prison. His parents were never charged with helping him escape and supporting him while he was on the run.
