^ Morgan may also have had quite a lot to drink, being that he was at a celebration that day and still drinking til 1.30 am..
If DJK was being predatory, seeing Morgan stagger home in bare feet might have been the opportunity he was looking for.
DJk probably -wasn't- drunk, so who knows what was said to Morgan to get him to let DJK into the flat? I can't assume it was a sex thing on Morgan's behalf, there's not enough info to support that.. but in he got.
Morgan could've simply passed out half undressed and been attacked from there. Alcohol can be a powerful sedative, if you have enough of it.. he could have been oblivious at that point.
The power/sex motive on the perp's behalf seems pretty spot on to me, tho.
I wonder after drinking, perhaps throughout the day, evening, how much was he really in the mood for sex
