If it was SH alone who put her in the loft and CS was not complicit in the death, maybe SH didn't have a chance to move the body. Events took over and before he could move her, CS or NS (not clear to me) reported her missing, the police arrived, the family descended on the house etc
It doesn't explain the funfair though.
Here's a bizarre coincidence - the very same ex-bf has the following written in another article about one of his other victims.
Mr H, who had been out at a fun fair in Mitcham that night, did not return to the house until 3am

I never knew the area had so many funfairs - Orpington, Atherton Rd (I think that's the one mentioned by SH or DS) and one in Mitcham??
