On the last mission make sure you did not let Emile kill Enrica earlier. On this mission you must go down a elevator to stop the bomb, but before you meet Enrica who opens the door for you. When she does that she will start walking off. Follow her, then kill her in the first room you come to on the left. This room is Enrica's. Go inside carrying her body and drop it by pressing Y on the sofa next to the bed. If it did not land on the sofa and stays there, keep trying. Then, jump up on the sofa or find a way onto it and pick up her body. Walk over on to her bed and press A to lay her body down. Her body will past through the bed.
