I remember that story. I will definitely revisit it by reading your link.

I read about a fellow who managed to mix with college kids while being in his thirties. He would hang out and party with the younger guys. It turned out that he would create opportunities to drug them and rape them. Like offer to take them home if they were too drunk to drive. He had been at this for a good while before he got caught because one of his victims woke up too soon. He would target straight boys. I don’t think anyone suspected he was even gay because he played his game so well. They never could find out how many victims he had in the end because most were too drugged to know what happened.
