Who killed Alison? In the pretty little liars?
In the books her twin killed her. But here is the twist in the books the girl that the girls thought was Alison was actually Courtney. So Alison killed Courtney. I'm watching the show too. I think it might be the same as the books but I don't know.
I don't know about the tv show, but if you mean the book, all I'm going to tell you is that Alison killed Alison, and it wasn't suicide.
I think it was that cop
didn't you see the last episode emily did!
We still don't know...love that show<3
