I agree with Alice here. It feels like a long shot, but it's worth a try.
If Phantomhive is a staff member it's likely he's the Overseer, by virtue of being in a place far away from the rest of us. Staff members aren't the only ones who kill in the Complex, after all. That'd give him more odds of staying alive and in control.
[Besides, Elizabeth has marked Alice as innocent. That by itself is another reason to listen to her suggestion]
