Berkowitz's adopted parents raised him as an only child. He had a half sister from his birth mother Betty Broder Falco after she put David up for adoption. The sister, named Roslyn did not have the same father as David. His biological father was a business man from Long Island, NY, named Joseph Kleinman. I have no information on Roslyn's biological father.
