1) The 36-year-old allegedly did not take into account that his girlfriend was highly inexperienced and had never undertaken an alpine high-altitude tour of this length.

2) He was also accused of starting the tour around two hours later than scheduled, while not carrying any sufficient emergency equipment.

3) Even when he had left his partner to get help, he allegedly did not bring her to a wind-protected place and did not use a bivouac sack or aluminum rescue blankets.

4) The boyfriend had also allowed his girlfriend to ascend the mountain with a splitboard and soft snow boots - equipment which is deemed unsuitable among mountaineers for a high-alpine tour in mixed terrain.

5) Given the harsh weather conditions with wind speeds of up to 46mph and temperatures of minus eight degrees - which felt like minus 20 degrees when combined - the defendant should have turned back earlier, according to the public prosecutor.

6) Despite the severity of his girlfriend's situation, the man has also been accused of failing to make an emergency call before nightfall. The defendant and his girlfriend were stranded from around 8.50pm, he allegedly did not give any distress signals when a police helicopter flew over at 10.50pm. After several attempts by the Alpine Police to contact the boyfriend, he finally spoke to an officer at around 00.35am. Although the content of the conversation remained unclear, the defendant did not contact the rescue services again following the conversation.

7) He had put his phone on silent and put it away, and therefore did not receive any further calls from the Alpine Police, according to the German news outlet.

------

I think gross negligence is a plausible argument here.
