Brock Bistro reveals that he found the victim sitting slumped over at a table… head on top of her folded arms.

We can rule out suicide because… if she bled out enough to form a large pool of blood on the floor, the white table cloth on which she died would have been soaked in blood, not just spilled coffee.

This proves that she had to be moved to the table once she bled out and died.

Furthermore, Ash claims that he threw his keys at her when he left but he was still able to produce the keys when Field-Marshall Mogau asked to see them. This leads us to believe that Ash Adams killed his girlfriend during their fight and tried to make it look like suicide!
