Since the beginning it has been pretty obvious that she's in the Hometown; specially because she herself said it in the extra pages of chapter 50 (I guess there's so much confusion because many people don't know about the existence of those pages) and because Reiner and Bertolt always made it clear that their plan was to take Eren and her over there. The only mystery is whether she's still alive or not, and if she's alive, in which conditions. Ymir guessed that the Hometown's plan was to feed her to a warrior and take back the Shifter powers she stole from Marcel, so if she hasn't been fed to someone yet, then she's probably in a cell.

BTW, I deleted that blog post precisely because it's a duplicate topic, since there's already this thread to discuss about it and people frequently ask the same question in many other threads.
