Who killed Alison in Pretty Little Liars the series?

Answer 1

Alison was never dead. She killed her twin sister Courtney. Courtney was pretending to be Alison while the real Alison was sent to a mental hospital by accident instead of Courtney.
Nobody killed Allison - nobody knew that Alison had a twin sister named Cameron and they had to send Cameron to a mental hospital but they sent the wrong twin and then Allison went to the mental hospitals and Cameron was playing Alison while she was gone and Alison came back the day of the barn and killed Cameron because she ruined her perfectly life and dumped her best friend Nahomi and became friends with the losers (they called them that) Aria,Hanna,Spencer, and Emily

• The Pretty Little Liars never knew that Ali actually had a twin named Courtney, who was insane. One day, Courtney managed to switch places with Ali. The Ali that all the girls knew was really Courtney! When the real Ali finally came back, she killed Courtney.
• YES! Courtney is really the dead one, not A(Ali)

• Ali never died. She has a twin sister named Courtney, who is sick in the head, who pretends to be Ali all along, while Ali is away at a mental home. Courtney becomes "friends" with the four girls and learns about all of their secrets and keeps it in a diary. When Courtney(Ali) is supposed to be coming back from the home to visit her family, the real Ali murders her sister in revenge.

• Okay, in the last book in the series, Wanted, you learn that Alison DiLaurentis had a twin sister named Courtney DiLaurentis, who didn't live with the family due to mental issues. The twins are identical. Later on you find out that 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 like the girls thought. 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 you discover that the actual 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.

• Alison is the killer.

• do you really want to know? i thought it was mellisa- spencers sister up until book 6- killer

• SPOILER FOR BOOK 6: In book 6 killer, the author leads you on to thinking it Jason (Ally's older bro) and officer Wildon, the four girls gets hints from Ian- who turns out isn't dead! obtw the new A is a lot nicer to the 4 liars :P

  Then at the very end of the last chapter in the book officer Wildon- I think sets Spencer's barn on fire, when Spencer, Emily, and Hannah are inside, Aria is outside of the barn. Aria then sees someone ( can't see their face ) trapped with a log on top of them un able to move. aria moves the log and sets them free, and helps them get away from the fire. all thee girls that were in the barn get out okay, and all 5 of them meet up, and aria explains what happened with this random person who was stuck, and they take the hood off that was up, and wipe off the soot and dirt from this persons face, and guess who it is....

  and of the 4 girls recognize this person, but they don't recognize all four of them....it was ALLY! idk how but shes not dead, they say in the books that there was a hole in the DNA testing and they never figured out if it acutally was ally that "died" , but i guess it wasnt!

• No one. Ali isn't dead.

• Ali killed Ali. They may not currently make sense but it will eventually. ali wasnt ali it was Courtney her twin sister ali killed Courtney

Alison DeLaurentis had a twin sister named Courtney, although none of the Pretty Little Liars knew it. They traded places and names, so Aria, Hanna, Spencer and Emily befriended Courtney under the name Ali. The REAL Alison killed her sister Courtney, but since the Liars didn't know there was a twin, they thought Ali was dead. The truth is that the Alison that THEY knew was dead, although the real one was alive. So Alison's killer is.... herself. "A" is Mona, Hanna's wannabe follower. When Mona dies at homecoming (population change, anyone?) Alison takes her place sending messages to the Liars. Ali knew everything about Aria, Hanna, Emily and Spencer because Courtney told her everything

Answer 2

No one did. Alison is still alive. Her twin sister, Courtney, was pretending to be Alison, but Alison killed Courtney for ruining her life and dumping her two cool friends for four losers.

Answer 3

Ali killed Ali! It's right out of one of the books. And it is completely true.
