An Austrian climber, accused of leaving his girlfriend stranded atop the country’s tallest peak leading to her untimely death from hypothermia, defended himself in court by stating, “she asked me to leave.” He faces charges of manslaughter.

In a courtroom filled with silence, 39-year-old Thomas Plamberger fought back tears as he recounted the tragic demise of his partner, Kerstin Gurtner, 33. Her death on the Grossglockner, which stands at 12,460 feet, made headlines globally.

In January 2024, Kerstin succumbed to the harsh conditions just 150 feet shy of the summit, where temperatures plummeted to a frigid minus 20 degrees Celsius.

Plamberger faces allegations of negligent homicide, with his trial commencing in a crowded Innsbruck courtroom. Media representatives worldwide were present, and spectators began lining up before dawn.

The proceedings were initiated by Judge Norbert Hofer, a specialist in mountain-related legalities and accidents, who inquired about Plamberger’s state of mind. Plamberger responded simply, “Good.”

He subsequently entered a plea of not guilty to the negligent homicide charge, which could result in a maximum prison term of three years if he is convicted.

Kurt Jelinek, representing Plamberger, claimed his girlfriend shouted at him to ‘Go!’ after he spent an hour and a half with her in freezing conditions.

But Plamberger is accused of making a series of mistakes on the trip which culminated in Kerstin’s death including being poorly equipped and failing to call for help despite realising the situation was critical.

The indictment against him reads that he left her ‘exhausted, hypothermic and disorientated’ – although Kerstin’s mother has backed Plamberger and is due to give evidence in the case. 

Speaking ahead of the trial she said: ’It makes me angry that Kerstin is being portrayed as a naive little thing who let herself be dragged up the mountain.

‘And I think it’s unfair how Kerstin’s boyfriend is being treated. There’s a witch hunt against him in the media and online.’

In opening remarks his lawyer said there had been a ‘misunderstanding’ between his client, and the pilot of a rescue helicopter the night of the tragedy which had led to her death.

Plamberger also told the judge he was ‘not a mountain guide but an amateur mountaineer’ and that although he had served in the Austrian army his experience was ‘self-taught’.

He explained how he had climbed the Grossglockner ‘14-15 times’ and that he had also watched videos on the internet to gain knowledge and experience of Alpine conditions.

Plamberger – dressed in a suit and pen necked white shirt – insisted they had always planned their climbs and hikes together and that Kerstin was ‘physically fit’ and they had often aborted climbs.

He described how he and Kerstin had been seeing each other for a year and had planned to move in together.

He said they would often go hiking and climbing in the mountains but also confirmed he had no ‘specific rescue skills’.

Fifteen witnesses – including Kerstin and Plamberger’s relatives – as well as mountain rescue teams, the helicopter pilot and forensic pathologist are due to give evidence at the trial which is expected to end later on Thursday.

At 7.10am webcam footage captured a helicopter soaring over the mountain, but the rescue mission had to be aborted due to strong winds

Just under three hours later, six rescuers were seen during their ascent, but Kerstin was tragically dead upon their arrival

Haunting webcam images show the glow of the couple’s two headtorches as they slowly edge towards the summit at around 6pm – almost 12 hours after setting off – then, hours later, only one light is seen as it moved down.

Rescue teams were unable to reach Kerstin until the following day due to hurricane-force winds, and she was found just below a cross that marks the summit.

Kerstin’s social media profile is illustrated with dozens of images of her and Plamberger climbing and hiking and she described herself as a ‘winter child’ and ‘mountain person’.

As part of their probe investigators examined their mobile phones, sports watches, laptops and photographs the couple had taken as they made their way to the summit before concluding he made several errors.

They highlighted how the couple were poorly equipped – Kerstin was wearing snowboard soft boots instead of proper hiking footwear – and officials say he ‘turned away’ despite a helicopter flying low over the area.

Through his lawyer, Kurt Jelinek, Plamberger has denied the allegations and insisted he turned away to get help, and it was simply a ‘tragic, fateful accident’.

In a statement announcing the charge Innsbruck prosecutor’s office said: ‘At approximately 2am on January 19, the defendant left his girlfriend unprotected, exhausted, hypothermic, and disoriented about 50 meters below the summit cross of the Grossglockner.

‘The woman froze to death. Since the defendant, unlike his girlfriend, was already very experienced with alpine high-altitude tours and had planned the tour, he was to be considered the responsible guide of the tour.’

They added he did not take into account that his girlfriend was highly inexperienced and had never undertaken an alpine high-altitude tour of this length.

He was also accused of scheduling the start of the climb around two hours later than prudent, while not carrying any sufficient emergency equipment.

Even when he had left his partner to get help, he apparently did not bring her to a wind-protected place and did not use a bivouac sack or aluminium rescue blankets, they said.

Given the harsh weather conditions with wind speeds of up to 46 mph 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.

They will also claim at the trial Plamberger and Kerstin were stranded from around 8.50pm, and he allegedly did not give any distress signals when a police helicopter flew over at 10.50pm.

After several attempts by the Alpine Police, he finally spoke to an officer at around 12.35am.

Officials say he had put his phone on silent and could not be contacted by Alpine Police but eventually at 3:30am, he decided to notify the rescue services, after having left Kerstin alone.
