On a warm summer Oklahoma day in 2008, two best friends - 13 year-old Taylor Paschal-Placker and 11 year-old Skyla Whitaker - went for a walk along a desolate dirt road near Taylor's home in the small town of Weleetka, on their way to a local creek, where they were going to hunt for pebbles and shells.  When they didn't return after darkness fell, Taylor's grandfather went looking for the girls - and came upon a scene no grandparent, parent or decent human being - ever should see.  The girls had been shot in the head and chest a total of 13 times with two different guns, their bodies left along the side of the dirt road.  Evidence later indicated that at least one of them had been sexually violated.  Despite the best efforts of law enforcement, the case went cold with absolutely no clues as to the identity of the monster who took the lives of these two beautiful girls...until three years later - in 2011 - when the monster revealed himself by killing Ashley Taylor - his fiancee - and setting her corpse ablaze on a relative's property.  But it was how the monster - then 25 year-old Kevin Sweat - revealed his crimes that sent a chill down the spines of everyone involved in the case.  Listen as Melissa  details the madness of Sweat's behavior and ponders the very nature of evil itself - are some people just born evil - or is there something somewhere - in an evildoer's past or biology that sets evil loose amid an otherwise sane world?
