Expert challenges Denmark submarine murder suspect’s defence

A leading submarine expert on Tuesday challenged Danish inventor Peter Madsen's claim that Swedish journalist Kim Wall was killed by toxic fumes in his homemade vessel last year, as he faces trial for her murder.

Madsen, 47, who is accused of premeditated murder, sexual assault and desecration of a corpse, has said her death was accidental since the first day of his trial on March 8th.

He said Wall, 30, died when a hatch fell on her head, but changed his story in October after autopsy concluded there had been no damage to the skull.

Madsen has admitted dismembering her body and throwing it overboard, but denies premeditated murder and sexual assault.

The self-taught engineer said the freelance journalist died when the air pressure suddenly dropped and toxic fumes filled his vessel on the night of August 10th, 2017, while he was up on deck.

Ditte Dyreborg, a prominent lieutenant commander with the Royal Danish Navy, said Madsen's explanations were implausible, if not impossible, as she spoke at Copenhagen City Court on Tuesday.

“We did not find anything. No CO (carbon monoxide), no CO2 (carbon dioxide), no NOx (nitrogen oxide). Which we would have if the submarine engine was running with carbon monoxide in it,” said Dyreborg, who was the first to inspect the vessel on August 11th.

Dyreborg also said that the delay in testing air composition inside the sub, which resulted from Madsen having initially given a different story as to how Wall died, would not have affected results.

“It makes no difference when measurements are made, because the air in the submarine was not changed in the meantime,” she said.

The witness also said that exhaust fumes Madsen claims filled the vessel could not have caused life-threatening conditions.

Madsen’s explanation of the accident also states that a drop in pressure inside the cabin, while he was on deck, prevented him from getting back inside to help Wall. He said that she must have switched the engines off herself, allowing him to get back inside once the pressure had stabilised, but not before the journalist had been poisoned by the fumes.

But Dyreborg said that explanation was improbable.

“I do not believe that Kim Wall was trapped inside the submarine and poisoned by exhaust fumes. There would have been clear signs on the filters if that was the case, and there were not,” the lieutenant commander said.

If the engines had stopped, it would have taken a long time before Madsen could open the hatch again, she also said.

She also doubted whether Wall, untrained in piloting the sub, would have been able to switch off the engines herself, according to DR’s report from the courtroom.

Seemingly irritated and agitated, Madsen took notes during Dyreborg's testimony and whispered technical questions into his lawyer's ear, according to an AFP reporter at the scene.

A coroner told a March 22nd hearing that there was no conclusive evidence to prove Wall's cause of death beyond doubt, adding she was probably strangled or had her throat cut.

The coroner could however not rule out poisoning as a result of toxic fumes.

Madsen's lawyer Betina Hald Engmark questioned the relevance of Dyreborg's expertise on smaller and private submarines, concluding the lieutenant commander did not carry out any tests on the vessel's air filters.

The prosecution, which is seeking a life sentence for Madsen, claims he tortured and killed Wall as part of a sexual fantasy.

Wall's body parts, weighed down with metal objects, were recovered from waters off Copenhagen. She also had 14 stab wounds to her genital area.

The first hearings focused on the inner workings of the eccentric inventor described by psychiatric experts as “perverse” and with “psychopathic traits”.

The verdict is expected on April 25th.



Danish 7-Eleven stores back on grid after ransomware attack

Almost all of 7-Eleven’s 176 Denmark locations are back up and running with the help of a backup system, the company said on Thursday. 

Danish 7-Eleven stores back on grid after ransomware attack

In an email to news wire Ritzau, 7-eleven said that over 96 percent of its convenience stores across Denmark were now in “stable operation”. That corresponds to around 169 stores.

“We have technicians at the remaining stores who are working hard to get them up and running as soon as possible,” the company said in the email.

However, convenience stores at train stations (where you can buy a transport card) were only accepting Dankort (debit card) payments as of Wednesday evening.

All operational stores outside of train stations currently accept Mobile Pay (app) and cash payments, and many can take Visa, Mastercard, and Dankort. 

“We expect that all stores outside of train stations can accept all Visa, Mastercard, and Dankort during the course of tomorrow morning, and all stores at train stations [will be able to] during the course of the week,” the company wrote late on Wednesday.

The convenience store chain was on Monday hit by a cyber attack that forced all of its 176 stores in Denmark to close.

7-Eleven has confirmed that the outage was due to a ransomware attack — hackers demanded money to return access to the company’s data and systems. 

The attack has been reported to police.

The company’s CEO, Jesper Østergaard, told Ritzau he did not know the extent of losses suffered by 7-Eleven as a result of the incident.
