Help Please

Someone told me recently how they were raped by someone I went to school with a few years ago. Of course I told them that I supported them and I want to help them but this happened probably three years ago and they are unsure if they want to go through a whole legal investigation. I'm sure they are also scared to bring such a traumatic experience to light. I want to support them in any decision but I am not sure that I am comfortable with letting this offender get away without doing anything. ESPECIALLY BECAUSE I KNOW THEIR FREAKING NAME AND FACE. Its kind of sickening actually. Does anyone know what I should do..? ╥﹏╥

This is first time I write at this place actually... Btw
