The article mentions, briefly, the case of the Austrian who was recently convicted of manslaughter for abandoning his girlfriend on the side of a mountain.

The story is apparently much much worse than it sounds from the brief coverage.

Rebecca Watson did a video on it recently: https://youtu.be/zf6rUxqrDes

There were, apparently, many many signs that things were not going well: beginning the hike too late in the day; passing a sign that said "do not continue if you have not reached this point by X time", despite reaching it hours later; Waving off a rescue helicopter; putting his phone in DND mode.

A former girlfriend testified that he has done basically the same thing to her years earlier, on the same mountain.
