A Tennessee couple who "defriended" Jenelle Potter on Facebook were murdered by her father and another man."This is just senseless," said Johnson County Sheriff Mike Reece told Reuters."We've had murders, but nothing like this."Jenelle Potter, 30, is one of those types who you just don't mess with. She is a Facebook fanatic who stays home with her parents and is constantly on Facebook.
