How was Mrs DiLaurentis supposed to hear Ali if she didn't make a sound? Ali said that she felt like she was screaming,but actually didn't say anything out loud.

Something I don't understand: The shovel was identified as the murder weapon in season 2. So there must be Ali's blood/DNA on it. Otherwise they wouldn't think that it's the murder weapon. How come that Ali was hit with a stone though, not a shovel? Why was Ali's DNA on the shovel?
