Who would have guessed that three of the most notorious, murderous men in recent history all share the same last name?  Not for nothing, ladies, but maybe if that dream date turns out to have a surname that starts with "P" and ends with "Eterson," you should reconsider Date No. 2.  In this, the first of a three-part series on three dudes who had no connection to each other - other than the name Peterson...and long interviews with homicide detectives...Melissa leads us down the raunchy life-path of Drew Peterson, a choice butthead of a fella, who thought so much of himself and so little of anyone else (especially the women who were unfortunate enough to enter his sphere) that he thought he could get away with disposing of two wives as if they were no more than yesterday's trash and get away with it.  In fact, it appears he still thinks he can.  A real prize package, this guy.  Melissa digs into the details of how the disappearance of Peterson's fourth wife - whose body has never been found - led to his arrest and conviction for the murder of his third wife - and how the determination of one victim's sister is leading to a final conclusion of both cases.
