Marlon Brando’s son, Christian, had a lot of inner turmoil, and it came to a head when he killed his sister’s boyfriend, Dag Drollet, after finding out that he’d been physically abusive toward her. Drollet was beating Brando’s sister while she was pregnant. He was shot to death in the Marlon Brando estate in Beverly Hils, California. Christian spent six years in prison for the crime and then years after being released, he ironically got arrested for domestic violence and pleaded guilty to beating his wife. His life ended early when he passed away from complications due to pneumonia.
