Alison's Attempted Killer

Alison's Attempted Killer is the anonymous character in Pretty Little Liars who attempted to kill Alison DiLaurentis by hitting a rock on her head during the Liars' sleepover on September 1, 2008. We still do not know whose body was found in the "Pilot", but Alison's attempted killer is possibly this person's killer as well.

We learn in A is for Answers that the person who tried to kill Alison and the person who buried her are two different people. Jessica DiLaurentis saw who hit Alison with a rock. Mrs. DiLaurentis buried Alison, thinking she was dead in order to cover for whoever tried to kill Ali. Ali was struggling inside of the ground, screaming and shouting to her mum saying,"I am alive! Can you not hear me?!" over and over again (or something close to that!) Alison had also heard her mum talking to someone as well! Whoever Jessica DiLaurentis was talking to, could be Ali's "killer".

Speculations
The Liars first suspect Toby Cavanaugh because Alison was wearing his sweater on the night she died. They thought that Toby was Alison's secret boyfriend, and that he killed her. They later clear him because of him admitting to Emily that his tattoo, '901 Free at Last', was the day that he was free from his forced relationship with Jenna, rather than the day Alison was killed.

Ezra Fitz is currently the new suspect of Alison's attempted killer. We know Ali was seeing an older boy shortly before she "died". He is seen in A's main lair at the end of "Now You See Me, Now You Don't." He is implied to be Board Shorts. Most people think it's Ezra. We learn in A is for Answers that Ezra did not try to kill Alison. She saw him that night, but they broke up with eachother and he left her unharmed. Ezra also stated thst he was just trying to write a book about Alison DiLaurentis and basically his journey whilst meeting and getting to know her.

The newest peron who is a popular theory is Jason DiLaurentis. We know he was drunk and high that night, so its possible he hit Alison thinking she was someone else. Mrs. DiLaurentis was protecting someone, possibly Ali's "Killer" or maybe even Jason; her son/ child. If she "lost" one child, then she wouldn't want to lose another
