I seem to recall a couple of news reports where JVS claimed that he thought about putting her into a suitcase and taking her out of the hotel that way- that he even attempted it but she didn't fit. Seems more likely to me that he attempted to bunch her up to see if she could be disposed of.
I've read of multitudes of beating deaths, and they don't end up in a fetal position unless they die slowly afterwards- the body does not automatically contract to fetal position from being beaten or dying. Curling up is a conscious brain process/reaction/defense, not an automatic body response. I can't see it hapening in an unconscious person. They go limp, not fetal.
Also, I thought I'd read that he said he had moved her? Wouldn't he have had to have moved her somewhat to have mopped up blood as he claimed?
