Two men charged in homicides of missing men
(CNN) —  

Danish inventor Peter Madsen is to be charged with the murder of Swedish journalist Kim Wall as well as “indecent interference with a human corpse,” Danish prosecutor Jakob Buch-Jepsen told CNN Thursday.

Madsen is currently in custody on a charge of manslaughter until September 5. The new charges will be filed on or before that date.

Buch-Jepsen also plans to request a mental evaluation of the suspect.

Wall, 30, had boarded a 17-meter submarine built by Madsen on August 10 for a story and was last seen on that day in an image that allegedly showed her standing with Madsen in the tower of the submarine in Copenhagen Harbor.

On Wednesday, Danish police said DNA from a headless torso found washed up on an island near Copenhagen matched that of Wall. Blood found on the submarine was also a match for Wall, chief investigator Jens Møller Jensen said.

This image is thought to be the final photo of Swedish journalist Kim Wall. She's seen standing with Peter Madsen in the tower of his private submarine on August 10, 2017 in Copenhagen Harbor.

Møller Jensen said the body had apparently been punctured to let the air out before sinking it, and it was weighted down in a presumed attempt to prevent it floating.

Madsen, 46, told a closed-door court hearing Monday that Wall had died in an accident and was buried at sea in an “unspecified place” in Køge Bay, according to a statement.

He originally claimed he had dropped her off on land on the night of August 10, according to a police statement. But police later said Madsen had provided them with a “different explanation.”

The submarine was found about 15 hours after it had departed Copenhagen, on August 11. Madsen was rescued from the sinking vessel by emergency crews but there was no trace of the missing journalist. He was charged with manslaughter and ordered to be held in custody for 24 days.

His lawyer, Betina Hald Engmark, told Denmark’s TV2 at the time that her client “accepts the arrest but still denies the crime.”

Wall’s former classmates at Columbia University Graduate School of Journalism in New York held a candlelight vigil Wednesday in her memory.

Her mother, Ingrid Wall, also posted a moving tribute to her daughter on Facebook, saying: “She gave a voice to weak, vulnerable and marginalized people. It’s a voice this world needed for years to come, but that has now been silenced.”

Journalist Susanne Gargiulo reported from Copenhagen and CNN’s Laura Smith-Spark wrote from London.
