STOCKHOLM (AFP) – Danish prosecutors said yesterday they will seek a murder charge against the submarine inventor who was last seen with Swedish journalist Kim Wall before her headless torso was found floating off Denmark. “At latest on September 5, we will try to hold him in custody on a murder charge … after her [dismembered] body was found,” special prosecutor Jakob Buch-Jepsen said, referring to Peter Madsen. The 46-year-old has been held in formal custody since August 12 on suspicion of “negligent manslaughter”. Prosecutors have until September 5 to request an extension of his custody. Mr Madsen, who has denied the allegations against him, has insisted Wall died in an accident on board.
