Authorities in Tennessee say a couple was allegedly shot dead in their home because they “unfriended” a woman on Facebook. The victims, Billy Clay Payne Jr. and Billie Jean Hayworth, had recently deleted Jenelle Potter from their friends list on Facebook. Following the “unfriending,” Marvin Potter, the 60-year-old father of Jenelle, shot the couple in the head and slit Payne Jr.’s throat.
