1996: Actress and model Margaux Hemingway, the older sister of actress Mariel Hemingway and the granddaughter of writer Ernest Hemingway, is found dead in her apartment in Santa Monica, California, at age 42. Hemingway's death, which came one day before the anniversary of her grandfather's suicide, was eventually ruled suicide by an overdose of phenobarbital. She started out as a model in the 1970s and made her film debut in the 1976 movie "Lipstick" alongside her sister.
