She didn't .
She killed her twin sister Courtney who was in a mental hospital .
One day Courtney switched with Ali and Ali was in the mental hospital .
The Pretty Little Liars didn't know Ali had a twin .
So Courtney was acting like Ali the whole time .
Courtney figured out all the pretty little liar secrets .
And wrote them in her diary . Ali was jealous and escaped from the hospital and killed Courtney .
Ali has been hiding in Jason's house the whole time .
What else can I help you with?
