So here's what you do. Get yourself a bag or 2 of frozen prawns. When the fat fuck waddles off for their 12 cheeseburger salad or whatever you pick the lock to her apartment. Get in there with your bag of frozen shrimp/prawns/crabmeat maybe a multi-bit screwdriver. Take your shellfish meat and hide it all over her place in hard to reach places. Vents, ducts, inside appliances(screwdriver), underneath furniture, inside closets, light fixtures, high ledges out of view, inside the couch, etc etc. Get out of there. Lock the door behind you or lock it and exit a window if you have to. First few days nothing will change. After a week or so she's not going to stomach more than a few minutes in her own suite. The smell will be so horrible with such well hidden sources it will be impossible to get rid of. Neighbors will complain. Landlord will be forced to resolve the issue.
