Forum:What did Riddle do in the Horcrux Cave?

Has anyone ever learned what exactly Tom Marvolo Riddle did in the Horcrux Cave as a youngster that traumatized Amy Benson and Dennis Bishop into silence? I have always been rather curious about that particular topic and did not know if anyone else has heard any mention made about it by Rowling. Anyone got any idea?
