With credit to Libby (Pll will put me in radley)  I think we need to discuss Polly as a possible BH suspect. No, BH does not look like a teenage girl but those of us who watched PLL know that the body type of a hooded figure can mean very little. And as Libby noted she could be wearing colored contacts.

Why Polly?

we know from last season she is part Blossom (third cousin to Cheryl or something like that) so she might have that crazy streak in her

She might have lost the baby due to stress or those milkshakes Penelope was giving her and that could have pushed her over the edge

She would know Betty took out the Nancy Drew book all the time, and also might have read Betty's diary

She may have killed Grundy because Grundy had a thing with Jason. We know Grundy worked with Jason, and his physical similarity to Archie means Grundy could have a "type."

Ok Libby, what am I forgetting here?
