Here is another good article, in german, but google translate is decent:

So it wasnt planned night climb.
8:30 PM - there are clear proofs that at this point they stopped moving.
He started his way down at
2:00 AM. 5,5 freaking H O U R S later.
What was he doing there if not making sure that rescue wont get there in time?
10:30 PM helicopter went up there.
Thats two hours of exposure right below the summit. And they both turned their heads away from it. How coherent and aware of circumstances may she be at this point?
So the "unfortunate event" scenario would mean that at this point they both felt pretty confident that she will fell well rested shortly and continue the hike? And he/they needed two more hours of contemplation to figure out that it may be appropriate time to call the rescue?
Then he calls the rescue? And he claims that he waited for them to come as long as he could before he realized that he cant stay with her any longer. Yeah.
A lot can be said about limitations in such weather conditions at this altitude and phones and so on, but...
Come on. There is not one scenario that holds up.
Wouldnt innocent, but so utterly stingy guy who would rather see his girlfriend and possibly even himself dead than pay for the helicopter be more interested in money if he could claim that he was doing whatever he possibly could to summon the rescuers before and was sure theyre on their way at 0:35 - as he later learned that his gf died and they didn't start until hours later?
Why not scream about it? Why not gofundme to sue them and change their ways and also get money?
And if he indeed called for help and knew thats on record, why would his lawyer go for some strange talk about "bad luck" instead of emphasizing on that, pointing out how he was doing whatever he could to help his gf listing what he did? If there was something, then there would be something to go on. Something better than "bad luck".
Also... isnt that kind of next-to-a-miracle level of outcome that a person who
wasnt planning to hike overnight, wasnt that careful with proper gear, wasnt that inclined to use thermo blankets or anything they HAD on them would be able to spend 5,5hours on over 12k ft mountain, in what felt like -20*C, facing strong wind and at some point just get up and continue his hike? For hours? With no frostbites?
That doesnt sound like a bad luck to me but the exact opposite. With the assumption that they were both on same page, no ill will involved, just bad side effects of cold and shared summit fever... that sounds like incredibly lucky scenario that even one of them survived.
