Who is the vampire who killed Sookie’s parents?

Or was it a vampire at all?

POSSIBLE SPOILER ALERT!

The books, apparently, have a fairy as the murderer of Sookie’s parents.

Of course, the books and the HBO series separated ways a long time ago (Lafayette would be dead already, according to the books). And her dad was only a fourth fairy in the books, which would have made Sookie just a half-fairy, instead of an eighth.

So that doesn’t mean a fairy will be responsible for Sookie’s parents’ death at all. I think we’re being led to believe it’s going to be Bill or Eric, but it’s actually going to be a fairy who was mad that Sookie’s dad had married a human.

So, who do you think killed Sookie’s parents?
