Or was she trying to give the impression she wasn't home!?!?
Possibly!!
Or was the killer trying to give that impression? The one article I read said family couldn't locate her at her house, and that cops went and searched and eventually located her body. I'll try to find it again, I think I linked it earlier. Anyway, the way it was written had me think she was hidden or concealed somewhere. Or at least not just in the middle of the floor... Possibly in her bed?
