A new true crime series debuting on the Investigation Discovery channel tonight puts the spotlight on a salacious story of murder and sex in Fayetteville.

"Scorned: Love Kills" (10 p.m., Investigation Discovery) opens with the story of the 2002 murder of U.S. Army Special Forces Maj. David Shannon. David and his wife Joan Shannon (left) were involved in the "swinging" lifestyle in Fayetteville (members of the "Fayetteville Gang Bangers," no less) but things got out of hand when Joan fell in love with one of her conquests and wanted out of her marriage. And since stupid people think murder is easier and cheaper than divorce, she started planning his death.

The grossest thing about this case is that Joan Shannon involves one of her teenage daughters in her plot.
