COPENHAGEN - Danish inventor Peter Madsen is on trial for the killing of journalist Kim Wall in his submarine. Madsen denies killing Wall and says she died while he was on deck. However, he has admitted dismembering the 30-year-old woman's body before he "buried her at sea."

With a verdict expected Wednesday, these are some of the key moments in the case:

— Aug 10: Kim Wall goes on submarine trip with Peter Madsen. They are the only two people on the sub. It is the last time Wall is seen alive.

— Aug. 11: Major search for submarine after Wall's Danish boyfriend alerted authorities that the sub had not returned. Madsen is saved from sinking submarine south of Copenhagen. Wall is nowhere to be found. Madsen is arrested and claims Wall disembarked from the submarine to a Copenhagen island several hours into their trip.

— Aug. 12: Madsen appears before a pre-trial custody hearing on preliminary charges of manslaughter while police investigate. In Denmark, preliminary charges are a step short of formal charges.

— Aug. 13: The submarine is raised and brought onshore in northern Copenhagen.

— Aug 21: The dismembered torso of Wall is found at sea off Copenhagen.

— Aug. 25: Madsen also faces preliminary charges of indecent handling of a corpse.

— Aug. 23: Copenhagen police says DNA test confirms it is Wall's torso.

— Sept. 5. During a four-hour pre-trial custody hearing, Madsen claims Wall died accidentally when she hit by a 70-kilogram (155-pound) hatch on the UC3 Nautilus submarine, after which he "buried" her at sea. He later changes that claim when Wall's head is found with no skull fractures.

— Oct. 4: Police say 15 stabs found on Wall's torso, and videos of women being tortured, decapitated and killed are found on Madsen's computer. They are not produced by Madsen but considered real (so-called snuff videos).

— Oct. 7: Police announce head, two legs and clothes found in plastic bags a day earlier. Dental records help in the identification of Wall.

— Nov. 22: Left arm is found by divers in the sea south of Copenhagen. Belongs to Wall.

— Nov. 29: Right arm is found by divers in the sea south of the Danish capital. Belongs to Wall.

— Jan. 12: Police stop searching for cellphones of Wall and Madsen believed to have been thrown at sea.

— Jan. 16: Madsen is charged with murder, dismemberment and indecent handling of a corpse, among other things.

— March. 8: Trial against Madsen starts at the Copenhagen City Court where he faces a judge and two jurors.

— April 25: Last trial day. Verdict to be announced.
