An American woman raped by filmmaker Roman Polanski as a teenager four decades ago pleaded with a Los Angeles judge Friday to end the case so she could move on with her life.

"I would implore you to do this for me, out of mercy for myself," Samantha Geimer, who was 13 at the time of the assault in 1977, told Los Angeles Superior Court Judge Scott Gordon.

"I am not speaking on behalf of Roman, but justice," she added, reading from a statement. "I implore you to consider to resolve this matter without incarcerating an 83-year-old man."
