As the investigation into the death of Swedish journalist Kim Wall continues, police said they might have recovered a saw used to dismember her body. The tool was found in the sea off Copenhagen and was being tested by forensic investigators to determine whether it was used in connection with Wall’s murder, according to CBS News.

Wall, 30, went missing August 10 after boarding the submarine of Danish inventor Peter Madsen as part of a story she was working on. Her torso was discovered a week later. Wall’s head and legs were discovered earlier in October stuffed in a bag alongside a knife and weighted down with metal pieces. Police said they were still searching for her arms.

Madsen, 46, was charged with manslaughter. The inventor pleaded not guilty to the charges and maintained Wall’s death was an accident that occurred when a heavy submarine hatch hit her in the head. Madsen alleged that he attempted to administer life saving measures but that when he realized Wall was dead, he steered the submarine out to the Baltic Sea where he slept at night with her body still on the craft before dumping her overboard. When he did so, he said, her “shoes and tights fell off.”

Prosecutors, however, alleged Madsen killed Wall sometime August 10 or 11, dismembered her and weighted her body down with metal to make it sink. Police believed he deliberately sunk the submarine after her death.

Police had not yet revealed Wall’s exact cause of death, but said she had 15 stab wounds alongside stitches on her body. Authorities also said they found videos that appeared to show women being tortured and decapitated on a computer they seized from Madsen.

A judge ruled Madsen would be held behind bars until October 31, at which point a court will decide whether he will stay in jail before the case goes to trial.

Wall was honored at a memorial service at Columbia University in New York City Wednesday evening, where friends and family remembered her journalistic prowess and read excerpts from some of her work.

“We have been deprived of all the untold stories,” her mother, Ingrid Wall, said at the ceremony.

“That’s exactly how we should remember and honor her,” said her brother, Tom Wall. “By remembering the words that she wrote. What she stood for. What she believed in.”
