Is My Tortoise Dead?

Hi, please I need a fast reply because I'm panicking.

I think my tortoise (mediterranean tortoise) died yesterday, is she supposed to be limp? She's not limp and its neck is not hanging out. However, she's not moving at all, not even a reflex on her legs. Also, I tried to open her mouth to give her some water but no matter how hard I pull it's closed shut (not as usual). Please how can I confirm that she's dead?
