Hi! It looks to me like the item under the lamp is a framed wedding photo of JC & MM? There's something else behind that, possibly the base of the overturned lamp - but it wouldn't be tall enough for a floor lamp and the base of the lamp looks intact, so I don't know.
Something else in these photos just clicked with me. You've probably debated this to bits previously, but I only just realised - and my stomach is churning since...
The 7th photo in this

it's the one with the vacuum behind the door. My eyes kind of slid off of this before, it's so gruesome. From what I remember, a big deal was made of the vacuum being moved, but I thought that it was because it had been horizontal and was moved to vertical or some such. It always struck me also that it was strange to have that there, with the lead across the door, in an otherwise beautifully appointed bedroom. The only other thing that's out of place is what looks like a courier or express post bag with the closing tab ripped off. No way it originally held the passports I suppose?
Anyhow, I'd assumed that the blood streaks on the floor under the door had been caused by the door opening/closing, but the direction of the streaks is all wrong. IMO it looks very much like the vacuum was used, to try to clean up! Was there any mention of the bristles being forensically examined?
So nothing new. But if that is the case, it is sick-sick-sick IMO. My stomach's still churning - ugh.
