The invitation onboard the UC3 Nautilus in Copenhagen was a response to Wall's request to meet him so she could write an article about him.Several horrific details of the death have emerged over the past few months. Prosecutors have found evidence that:Wall died either from strangulation or having her throat cut.Her body was dismembered, with chunks of metal attached to her remains apparently so they would sink to the bottom of the sea.Herhead, legs, and clothes were dumped in a plastic bag in the sea.Madsen used a saw, knife, and tapered screwdrivers to hit, cut, and stab Wall before she died.Wall was stabbed multiple times in the genitals, according to a post-mortem exam of her remains.She alsostabbed with syringes, which resulted in needlestick wounds on parts of her body.The journalist wasstrapped to pipes inside Madsen's vessel, likely with straps Madsen had brought on board or with her own stockings.A Copenhagen court on Wednesday found Madsen guilty of murder, and sexual assault without intercourse for the stabbing of Wall's genitals, tweeted Julie Thomsen, a reporter covering the trial.Madsen previously denied murder and sexual assault, and changed his story a number of times. He claimed immediately after Wall's body parts were found that a metal hatch inside the submarine slammed shut on her and killed her, then said shedied of carbon monoxide poisoning.In court he admitted, however, dismembering her body in order to lift it out of the vessel's hatch."What do you do when you have a big problem'" he said, according to Sky News. "You divide it into something smaller."Click here for Business Insider's full coverage of Kim Wall's disappearance and Madsen's trial.Join the conversation about this storyNOW WATCH: Jared Kushner and Ivanka Trump tried to cut a secret deal with Planned Parenthood ' here's what happened
