From Ali's Little Lies you find out why. Its because she was saying "Im not Courtney. Im Ali" all the time so her parents got suspisious (and then concluded that she was actually Courtney and mental) and also Mrs. DiLaurentis asks  Real Ali if she saw Ali (Real Courtney) the night she died. Real Ali then had a guilty/sinister expression cross her face and then her mom knew something was up. So, she locked her in a room and then shortly after sent her away to the Preserve (with much difficulty)
