The account of a climber who left his girlfriend to freeze to death on Austria’s highest mountain does not add up with how her body was discovered, a court heard today.
Thomas Plamberger, 39, is standing trial accused of negligent homicide after girlfriend, Kerstin Gurtner, 33, died just 150ft below the summit of the 12,460ft Grossglockner in January last year as temperatures plunged to minus 20C.
He is accused of leaving Gurtner ‘exhausted, hypothermic and disoriented’ while he went to get help.
During his trial, which opened today in Innsbruck, Plamberger claimed his girlfriend shouted at him to ‘Go!’ after he spent an hour and a half with her in freezing conditions.
But Judge Norbert Hofer found the circumstances of how Gurtner’s body was found inconsistent with Plamberger’s explanations.
The judge showed a photograph of Gurtner hanging freely from the rock face – indicating that she had fallen, he said. Her boyfriend claimed he had left her at a different location.
The head of the mountain rescue team confirmed that Gurtner was not found where the defendant had indicated he left her and said she appeared to have tried to climb down the mountain.
‘It was certainly not a pretty sight for us when the woman was found,’ he told the court.
Plamberger earlier 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 a necked white shirt – insisted they had always planned their climbs and hikes together and that Gurtner was ‘physically fit’.
He described how he and Gurtner 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’.
Plamberger is accused of making a series of mistakes on the trip, which culminated in Gurtner’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 disoriented’ – although Gurtner’s mother has backed Plamberger.
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.
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 Gurtner until the following day due to hurricane-force winds, and she was found just below a cross that marks the summit.
Gurtner’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 – Gurtner 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.’
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 that Plamberger and Gurtner 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 Gurtner alone.
