Swedish journalist Kim Wall died by accident after being hit by a hatch cover on board a submarine, the Danish owner of the vessel has told a court.
Peter Madsen said he had been holding the heavy hatch - but then lost his foothold and the hatch shut.
Mr Madsen then said he had tried to bury Ms Wall at sea and intended to commit suicide.
He has been charged with killing Ms Wall, whose headless torso was found on 23 August in waters off Denmark.
She was last seen alive on 10 August as she departed with Mr Madsen on his home-made submarine.
