NASHVILLE, Tenn (Reuters) - A Tennessee couple who “defriended” a woman on Facebook were murdered in their home by the jilted woman’s father and another man, police said on Thursday.

“It’s the worst thing I’ve ever seen,” Johnson County Sheriff Mike Reece said, adding he had never seen anything like it in his 27 years in law enforcement in the area. “We’ve had murders, but nothing like this. This is just senseless.”

He said Billy Clay Payne, Jr. and Billie Jean Hayworth were killed last month after they deleted Jenelle Potter, the daughter of one of the suspects, from their “friends” list. Both were shot in the head and the man had his throat cut.

The couple’s 8-month-old baby was in the mother’s arms, unharmed, when the bodies were found.
