STOCKHOLM — The Danish police said on Saturday that divers had recovered the severed head and legs of the Swedish journalist Kim Wall in a bay, as well as crucial evidence that is inconsistent with a Danish inventor’s explanation of how she had died on his submarine.

Jens Moller, the chief investigator in the case, said at a news conference outside Police Headquarters in Copenhagen that the divers had found plastic bags containing the body parts and clothing belonging to Ms. Wall in Koge Bay, southwest of Copenhagen, on Friday.

“We have found the head and two legs, but we have not found her arms,” Mr. Moller said.

Ms. Wall disappeared after meeting Peter Madsen, 46, an amateur space rocket and submarine builder, for an interview on Aug. 10 and a trip on his homemade submarine. Her torso was found on a beach on Amager Island, near Copenhagen, 11 days later. He was later charged with manslaughter, which in Danish law is the equivalent of murder.

Medical examiners who inspected the new evidence on Friday night used dental records to identify the head, which did not show any damage to the cranium, Mr. Moller said.
