A few more shots of the bedroom in this video at minutes 2.21 and 2.27 - one showing the suitcase in the wardrobe that was found to have blood inside it.
Thanks for the link. I think based on the blood spatters and an assumption the bathroom is on the left, his story seems highly unlikely he didn't notice the body. He would've basically tripped over it. As soon as they saw the room they must have rolled their eyes.
