A is not Mona it is Ali. The DiLaurentis had three children Jason, Alison and Courtney. Alison and Courney are identical twins. Well Courtney always pretended to be Alison, causing much confusion amongst the DiLaurentis family. The night that "Alison" disappeared, it was really Courtney in Spencer Hasting's barn, not Alison.

Alison despised Courtney because back awhile ago, Courtney dumped Alison's popular friend Naomi, and traded her for 4 new "losers," who just so happened to be Hanna, Spencer, Aria, and Emily. Many of the girls adventures with whom they thought they shared with Alison, were actually with Courtney who pretended to be Alison. In the end Alison (Ali) killed Courtney for throwing away her perfect life. The body that was discovered in Maya's backyard was Courtney DiLaurentis. Ali is still alive, but after Mona Vanderwaal dies, Ali takes on the role of "A."

So in conclusion, Alison is the killer, and she killed her twin sister, Courtney out of fury and revenge. Ali soon plots to kill aria hanna emily and spencer but they escape. everyone thinks ali (the real one ) died in the fire when she tried killing aria spencer hanna and emily.
