Could they have really proved he was The Bay Harbor Butcher?
Assuming thats why Dexter got desperate and killed Logan to escape, he knew Batista was coming and i guess knew he was gonna be exposed as The Bay Harbor Butcher and had no choice but to run.
But really could they prove he was him? Dexter faking his death could be explained by what he told Angela, he just felt he was cursed and everyone would be better off if he was gone. I guess the needle marks and same drug link them but its still a stretch imo, there was no bodies chopped up in iron Lake.
i just don't think there was concrete proof he's The Bay Harbor Butcher, if he stayed in custody he could have gotten off imo.
