^ Hun, Mona accidentally killed Charlotte. Her neck was snapped, then Mona threw her off the tower to make it into a suicide. Obviously A.D. didn't know that until the events of "Farewell, My Lovely", so they decided to take a page out of Charlotte's A-book and torture the Liars until someone fessed up.

Although it was accidental, A.D. still views Mona as the true killer.
