Reposting this as I've changed a couple of points....
Just doing a rewind to yesterday it seems the chequered pyjamas are a big part of this case now. We don't know yet if they were missing or not.
However, if they are missing this is what I'm thinking may have occurred.
I think she was murdered in that bedroom. He dragged her by her feet (see QC Fuller's opening address) out through the door leading onto patio. Her hair & sloppy joe/tracksuit top collects the leaves along the way.
He bundled her body into the Captiva just outside in the carport. '
On the way to Kholo a trickle of blood comes from her mouth or nose or ear. He dumps her under the bridge.
But either at that moment or later, he realises his "she went for a walk" story won't fit with her still wearing pyjamas so "himself" OR "someone else" returns to Kholo with the pair of 3/4 length pants = interfering with a corpse.
