Lavrentiy Beria, the head of the secret police in Stalin's USSR was a serial rapist and murderer. He had at least hundreds women and children kidnapped off the street, both people who weren't missed but also celebrities, and raped them and then murdered them if they wouldn't pretend it was consensual.
