Talk:Alison's Attempted Killer/@comment-94.71.141.110-20130819125353

I believe Alisons killer is either Aria or Spencer.

Another possibility could be Cece or Alisons twin sister (if she has one.)

Aria was furious with Alison because she threatened to tell her mom about her fathers relationship with Meredith.

Spencer was also furious with Alison because she forced her to tell her sister about her kissing Ian.

Cece had also a motive in killing Alison.She wanted to take revenge because Alison had her kicked  out of college.
