The Danish man accused of murdering and dismembering Swedish journalist Kim Wall was charged in her death on Tuesday, months after an investigation began. Prosecutors say Peter Madsen, an inventor, either strangled Wall or cut her throat before throwing her body parts out to sea and intentionally sinking his own private submarine in August. Prosecutor Jakob Buch-Jepsen has called the case “very unusual and extremely disturbing.” Madsen initially claimed that he dropped Wall off safely on an island then later said she died of an accident on board the submarine. He has admitted to throwing her body parts into the ocean. Madsen’s trial is scheduled for March 8.
