Who killed Ali in the TV series Pretty Little Liars?

Answer 1

Okay So Ali was not killed until the last book. The person who was killed was her twin sister. OK so when her sister came in town from a mental place she swapped lives with Ali. And there parents did not believe because the sister always said she was Ali. And the real came back form a new mental place she killed her sister. She also killed Ian. And Jenna who her dead twin made blind. And she also kidnapped one of her dead sister's friend sister. And she tried to kill 4 of her dead sister's friends but ended up killing her self. But you should really just read the books the end all the books on 3/15/11. It would make a lot more sense.

- A

And read the books to know who A is

Answer 2

Ali was allegedly killed by her identical twin sister, Courtney, although it is later revealed that Courtney was the one who was killed. Courtney suffered from paranoid schizophrenia, and her parents wanted to send her to a hospital. Alison and Courtney switched places, and Alison was sent to the hospital instead. Nobody believes Alison when she says that she is who she is. Meanwhile, Courtney is living Alison's life for her in Philadelphia. Alison ends up killing Courtney.

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.

Answer 4

Ali is not dead. She is still alive.

It was Courtney's body they found, not Ali's

Ali becomes new A.
