Quite a bit more info out today. I can't help wondering if DJK asked to use the toilet or something to gain entry into MH's unit. Because Morgan likely knew him by sight (maybe even said hello in the past), DJK may have said he just finished work and was busting to go before he walked home.
Of course I'm still bouncing round the idea of a prearranged meeting, mainly because of the CCTV that shows Morgan pausing on the street. I wonder if Morgan was seen looking at his phone in those few minutes. There is that barmaid that said she couldn't meet up with him that night. Is it a possibility that he got a text or call from her whilst standing there - indicating they wouldn't be meeting up. I don't know. So much points to a prearranged meeting with DJK and MH, but I just think something is off.
