Kasia Lenhardt's death came as a shock as Berlin police on Tuesday reported finding a "lifeless person" in the city's upscale Charlottenburg section. Initial investigation suggests that the model took her own life in her home and nothing suspicious has been discovered so far. The Polish model reportedly killed herself on her son Noah's sixth birthday, just a week after splitting from her ex-boyfriend and City star Jerome Boateng. The model was 25.
