It's probably the most well-known murder in Hollywood after the Black Dahlia so I'll spare the long introduction. Charles Manson's "family" breaks into the Polanski residence and kills Sharon Tate and Roman Polanski among others. In a bitter twist, some accounts claim Polanski wasn't expecting to be home at the time but decided to return from working publicity for Rosemary's Baby and attend to his very pregnant wife. Of course, everyone remembers Rosemary's Baby as a great film today, Roman Polanski's unexpected swansong, but as with any great artist one has to wonder what he could've produced had he lived.
