Have been lurking for a while, you all have some great theories, so I thought I'd share my thoughts.
I've been following this case with interest as I live very local, in fact I drive down Watson St most days, I buy take away's from a lot of the places mentioned in the various articles, Crust in particular. The riot squad was searching outside my building for the murder weapon one day.
There are a few things that just don't quite add up for me. In fact my first thought before it was even revealed that MH was a 'ladies man' was a Grindr hook up gone wrong. I guess being a gay guy who uses Grindr in the area, it was something that came to mind. I don't ever recall ever seeing MH or DJK on the app, but then I don't remember everyones profile who I just may casually browse over. Or they may not have had face pics.
I think they knew each other prior, and had previously met up for sex. It's not uncommon for a guy just to enjoy sex, MH may not have even been bi or bi curious, he just enjoyed the sex, whether male or female, but it was just that, sex, nothing more.
It seems odd to me that MH went to the Oaks alone, he seemed a popular guy, had been out all with friends etc, why not stay on with them if he wanted to continue drinking. Was he a bit early for his pre-arranged meet up time? So had a beer to fill in time. Was DJK late, that's why he left the house with no shoes, but ended up staying for a beer to fill in the time. It also seems odd that he exited onto Ben Boyd Rd, and paced up and down a few times as reported. If he was just heading straight back home, he could have used the doors on Military Rd and walked to the lights at Watson St.
We are unsure where DJK was working, if at all, there are quite a few take away places opposite the Oaks (Kebab shop etc), perhaps he was working as a kitchen hand at one of these that night (casual cash in hand job?) and MH was waiting for him to finish his shift? Or they simply had planned to meet at that location, because MH wanted to go home first to check the coast was clear for him to come over? His flatmate may well have been aware of what MH was up to but he still liked to keep it discreet, ie check she didn't have friends over and they were socialising in the living room etc.
It's not uncommon for people to meet up for 'discreet' sex, basically entailing even if you were to pass each other in the street you don't acknowledge each other and that's that. I'm just not sure how they would have come across each other in the first place. Maybe DJK had observed MH using particular websites at the internet case. Because again if you have a computer at home/smart phone etc, why else are you using the internet at an internet cafe. He may have approached him in person, or tracked down the online profile and started chatting with him and they decided to meet up?
This is where I then think DJK became obsessed, infatuated even with MH, perhaps stalking him to a point, he may not have even intended to kill him that night, but after they had 'had some fun', MH half asleep basically told him to let himself and drifted off to sleep at this point, DJK snapped at this point having a fantasy in his head about MH and himself, grabbed a knife from his 'chefs kit' stabbing and incapacitating him before he had any idea what was going on.
It could also be this scenario but he was paying DJK for the sex, again this is not uncommon. But DJK becoming obsessed with MH, and to MH it was just sex and DJK wanted more from him. The money he allegedly stole could have in fact have been intended for him? Perhaps the amount found matched an ATM withdrawal of MH's from that evening or days prior.
The initial reports were that MH had been having sex with a woman prior to his death. Could it just be that it was assumed at the time it was a woman? Evidence in the room of a female may have been from days prior? And after further investigations it revealed he'd in fact been having sex with a male, these details were never made public and that when the investigation took a turn? Initially they may have been scrutinising the footage looking for a female and had discounted DJK in the footage in the initial investigations.
Anyways that's just my thoughts, probably way off but who knows.
