Danish prosecutors on Tuesday formally charged inventor Peter Madsen with the August 2017 murder of Swedish journalist Kim Wall, whose dismembered body parts were found at sea after she interviewed him on his homemade submarine.

Madsen, who was arrested and detained shortly after Wall's disappearance, has admitted cutting up her body and dumping it at sea but has denied intentionally killing her. His trial will begin on March 8, charged with premeditated murder, as well as dismemberment and "sexual relations other than intercourse of a particularly dangerous nature", prosecutors said.
