i dont think its vogel, my theory is
that its ol boy who was going out with cassie....it wouldnt make sense for them to show quinn continuing his investigation if it was him
show fell off
Quinn killed 2 people last year without batting an eye, he is a murderer, and this would make no sense at even for this show, for a brand new guy to come in, take out his neighbor and then kill her to frame Dexter, it has to be Quinn mad the world that he is a failure and loser getting revenge for Deb his lost love, trying to destroy the man she worships her brother who is perfect. He has motive and i can't see 60 something Vogel getting the best of healthy grown men unless she drugging them like Hannah.Why kill someone right next to dexter tho...
Why would Quinn even be around dexter's apt like that.
Quinn maybe dirty but he ain't doing murders he just moved in with Jamie...
It has to be someone close to dexter to plant zack in his chair.
My thing is zack apparently didn't seem to have anything wrong with him so either he was drugged or trusted the person that killed him.
