CAUTION: The post below is strictly a dream sequence and did not happen to the author in real life. However it contains descriptions of the deceased and might offend some readers.
It's still in your backyard because you haven't been able to get rid of it. You don't want to even think about it during the day, not when eyes are most watchful and you can't do anything about it.
Night falls and weariness sets in. You go around to the back of the house and finds that it's still lying there among the garbage, wrapped in an exceptionally white cloth. You drag it through the back door into the kitchen. Open it up and you see the body of a beautiful woman - naked, fair, and moth-eaten. Her face isn't too deformed that you can't remember her from somewhere. You might have been in love with her even. You don't know for sure. It's too late to know such a thing for sure. She's a corpse now and she can't stick around. The nearest garbage dump isn't near enough to avoid the neighbours' suspicion.
Anyway she has to go...
