More than a year after a young woman froze to death high on Austria’s tallest mountain, her boyfriend is now standing trial in a case that is testing the limits of personal responsibility in extreme sport.
Kerstin G, 33, died of hypothermia during a winter climb on the 3,798 metre Grossglockner. Prosecutors say her boyfriend, identified in Austrian media as Thomas P, left her exhausted and unprotected near the summit in storm conditions in the early hours of January 19, 2025, while he went to seek help. He denies gross negligent manslaughter, calling her death a tragic accident.

The trial, which opened in Innsbruck, has drawn attention far beyond Austria. At its heart lies a difficult question. When does a shared decision to take risks in the mountains become a crime?
According to state prosecutors, Thomas P was the more experienced climber and should be regarded as the responsible guide for the tour. They argue he planned the climb and failed to turn back or call for support in time, despite worsening weather and his girlfriend’s limited experience at that altitude and difficulty.
They allege a string of errors from the outset. The couple, they say, began their ascent two hours too late in challenging winter conditions. Kerstin G had never completed an Alpine tour of that length and difficulty, prosecutors argue, yet the climb went ahead. They also claim there was not enough emergency bivouac equipment and that she was allowed to wear snowboard soft boots, which they say were unsuitable for mixed high altitude terrain.

Thomas P disputes those claims. His lawyer, Kurt Jelinek, says the couple planned the tour together and both believed they were sufficiently experienced, well prepared, and physically fit. “Both considered themselves to be sufficiently experienced, adequately prepared, and well equipped,” Mr Jelinek said. He added that his client is deeply sorry and extends his sincere condolences to the family.
Weather conditions are central to the case. Prosecutors say that once on the mountain, the couple should have turned back as winds reached up to 74 kilometres per hour and temperatures dropped to minus eight degrees Celsius, with wind chill making it feel closer to minus twenty. They did not turn back.
Accounts diverge over what happened next.
The defence says the pair reached a point known as Frühstücksplatz early in the afternoon of 18 January and continued because neither felt exhausted or overwhelmed. Prosecutors say they became stuck later that evening and that Thomas P failed to call police or signal for help, even when a helicopter flew overhead.
Webcam images captured the beams of their head torches as they climbed through the darkness. Shortly after midnight, the situation changed. According to the defence, Kerstin G suddenly showed signs of severe exhaustion when it was too late to retreat. Thomas P called the mountain police at 00:35, though what was said during that call is disputed.
Prosecutors allege he left her near the summit around 02:00 without properly insulating her from the cold and did not alert emergency services again until 03:30. By then, strong winds made helicopter rescue impossible during the night.
Kerstin G died alone on the mountainside.
Her social media posts show a keen mountaineer who loved hiking at night. Her mother told German media that the mountains were her daughter’s passion.
If convicted, Thomas P faces up to three years in prison. But the consequences may stretch further. As Austria’s Der Standard newspaper has noted, a guilty verdict could mark a turning point for mountain sports, redefining how far one climber is legally responsible for another.
As the BBC reports, the case has sparked debate across mountaineering communities about risk, trust, and the fine line between tragedy and criminal liability. In a sport where judgment calls are constant and conditions can change in minutes, the court must now decide whether this was a fatal miscalculation or a crime.
