It was sometime after midnight in February 1974, not long after the Valentine's Day Dance at Western Hills High School had ended in the Fort Worth suburb of Benbrook, Texas.  17 year-old Carla Walker and her boyfriend, high school football star Rodney McCoy, were in the front seat of Rodney's mom's 1969 LTD doing what teenage couples in love tend to do in cars on a Saturday night.  Suddenly,the passenger side front door flung open, Rodney was repeatedly pistol-whipped and Carla, who was dragged out from underneath him,told the man - or was it men? - to stop hitting her boyfriend - that she would go with him/them.  "Go get Daddy" were the last words Rodney heard Carla shout as she was taken away - and just before he passed out.  Just three days later, Carla's body was found in a culvert in a remote area near Benbrook Lake.  She had been tortured, raped and strangled to death.  Rodney, who had bruises and cuts from his attack, could barely describe the assailant(s).  To this day, Rodney can't say for certain who beat him and abducted Carla.  The case became the most-reported case in Texas in 1974 and is still one of the most sensational unsolved murder mysteries in the state's history.  Listen in as Melissa goes over all the known facts of the case - including a blockbuster letter received by police just days after Carla's body was discovered which was just released by the authorities last year - and the far-too-coincidental min-life story of one William "Ted" Willhoit - a nasty character who may just be at the heart of solving this case once and for all if but for just one crucial tip from someone who knows something they're unwilling - or too afraid - to tell.
