One of the culprits apparantly sat on him to make sure that he couldn't move, breaking several ribs..
Yes, apparently. As in not conclusively proven or admitted to by the defendants.
You and your German newspapers (they are all left of center) are conveniently forgetting that the public has been regularly subjected to unsolicited images of gay men and women at their so-called "pride" marches (a collective act of obedience rather than solidarity and defiance).
Their infantile attention seeking behavior captured on-cue for the cameras at these marches always involves them wearing lots of leather such as dog collars, face masks, harnesses and pseudo-Nazi uniform attire. Clearly none of this sort of get-up is used for flower arranging classes or Tupperware parties but are standard gear for their sadomasochism with each other.
Your anti-Polish OP cohort even said the accused men were "certainly homosexual." Whether they were or not your own posts take the position that heterosexual men should not object to be sexually propositioned by homosexuals (but certainly and most hypocritically you would be in spitting outrage if the two male defendants had propositioned a female for sex).
Therefore it cannot be discounted that if sex was involved between the victim and the accused that consent was given even if it was very rough and got way out of hand. Nothing was mentioned about the victim crying out or raising an alarm for help.
But as already mentioned the victim may have engaged in a sex act on his own after the two men left that resulted in his death. Whatever he was doing could have resulted in him losing his balance, falling face first into a chair which would have knocked out his teeth, and landing on the floor breaking his ribs. A fall would also explain aggravated internal injuries. Anyone can self-harm as well by burning themselves with their own cigarettes. Indeed, your German press said his partner didn't want him any more so he had to move out. Being rejected would explain such behavior.
There have been plenty of media stories too of celebrities found naked and hanging by the neck from the back of door. At first speculation always swirled around suicide from depression or even being murdered by other people they were seen with that day. But then the truth would come out and they were actually engaging in autoerotic asphyxiation and died from their own negligent and self-gratifying activity.
and the tiny fact that their DNA was [found] on the murder weapons, small details
It's the 21st century. Your communist show trials are a thing of the past and completely discredited.
The two men have only been accused and they have not been convicted.
Even your cohort admits this:
They apparantly found the dna of the suspects on several items that were used.
Indeed, apparently. I'm sure if you were in that same room the day before your DNA would have been on several items as well.
