Check the Hall of the Dead in Solitude. You may be able to find her body there.

Vittoria Vici

Yes. You go into the catacombs (hall of dead is connected to it but is a seperate house). If you enter from catacombs entrance, hug the right wall. Look in all coffins. If u pass the first wall, you have gone too far. Torch or night eye very helpful. Oh and this is on xbox 360 not sure about pc.

Depends Xbox or PC?Your only option is resetting before if you want the items.

No unless you had a save
