Except it was Dexter who decided Yates was the Bad Guy, because Dexter saw the scars. Vogel's just namin' names for "might be"s, but Dexter's the one who looked at the scar and said, "It's him!" Vogel's playing along like she doesn't know better, or she might be altering method, or... I dunno. I don't trust her even a little bit. But I am pretty damned sure she killed Dex's dad. That he was murdered by *someone* was obvious before this season... just didn't know who had the motive. It could be the retired/unretired chief, too. He's tight with Vogel, and he's definitely skeevy when it comes to actually following the lines. He'd kill/let someone be killed, I think, if it followed his own interests-- remember Dex's dad covering for him after some shady stuff in the flash back. I dunno. I could be wrong, but I think there's gonna be some house cleaning going on. Ev'rb'dy dies.
