A Danish inventor charged with murder in the death of Swedish journalist Kim Wall told the Copenhagen City Court that her death was an accident.
Peter Madsen testified Tuesday, saying he was holding the hatch of his self-built submarine open when he lost his grip. He said the hatch cover fell onto her head, badly injuring her, CNN reports.
“It was a terrible accident, a disaster, no doctor could have done anything,” he told the court, according to The Guardian. “Kim was severely injured. There was a pool of blood where she landed. I touched her neck, but she had no pulse.”
Madsen said he contemplated suicide but decided to try to sink her body instead.
After hearing Madsen's tesitmony, the judge ordered that he be detained for four more weeks.
Danish police identified the disembodied female torso washed ashore in Copenhagen as that of Swedish journalist Kim Wall. Authorities believe she was murdered by a Danish inventor while researching for a story aboard his home-made submarine.
Inventor Peter Madsen maintains his innocence, saying Wall died in an accident and that he "buried" her at sea. In a conflicting initial statement to police, he had said he last saw Wall when he brought the journalist back to Copenhagen, alive, on the night of Aug. 10.
Police spokesman Jens Moller said metal had been attached to the woman's torso, indicating someone wanted "to make sure the body would sink to the bottom."
The torso was found without arms, legs, or a head in Amager, Denmark. Authorities do not yet know the cause of death, and crews are searching for other body parts.
The day after Madsen took the journalist out to sea, Madsen was rescued when his UC3 Nautilus submarine sank. Investigators believe Madsen sank his vessel on purpose, although he claimed he had been fixing a defect and only made the problem worse, causing it to sink.
Madsen, a self-described "inventrepaneur," was somewhat of a public figure in Denmark, known for his three crowdfunded, home-made submarines.
Wall was a 30-year-old freelance journalist from Sweden, and had degrees from Columbia University in New York, as well as the London School of Economics. Her reporting has appeared in The New York Times, The Guardian, TIME, The Atlantic, and others.
