Is this who the Riverdale masked killer really is?

Riverdale is everything right now, there's no denying that, but the question on everyone's lips is who shot Fred Andrews along with three others.

Fans of the show have created a few theories that blow our mind, but just might be right on the money.

The second theory is Ms Grundy's ex:

 The final one is Sherriff Keller!

Who have you got your money on?
