- Danish inventor Peter Madsen was charged with murdering journalist Kim Wall last week.
- He was the last person seen with Wall after inviting her on his submarine.
- According to the full indictment, Madsen tortured Wall with a saw, knife, and screwdrivers.
- He then dismembered Wall's body and dumped the parts into the water, prosecutors said.
An eccentric Danish inventor used a saw and screwdrivers to hit, cut, and stab journalist Kim Wall before she died, Danish prosecutors have said.
Madsen, an entrepreneur and aerospace engineer, was the last person seen with Wall after he invited her on his submarine - the UC3 Nautilus - in August 2017. Wall, a 30-year-old freelance journalist, had been researching him for an article.
Peter Madsen was formally charged with murdering Wall last week, but the full details of his indictment were only made available on Tuesday.
According to the indictment, which was seen by Business Insider, Madsen pre-planned the murder, and brought to the boat a saw, knife, tapered screwdrivers, and straps, which he used to tie Wall's head, arms, and legs.
He then used the rest of the tools to hit, cut, and stab the journalist, before dismembering her and dumping her limbs into the water, prosecutors said.
Wall's exact cause of death remains unknown, but prosecutors said she died by strangulation or from the cutting of her throat.
Danish police said last week that Madsen was informed of the indictment, but did not specify his response.
His trial by jury is scheduled to take place in Copenhagen on March 8.
