This same thing happened in my old hall. An elder was studying with a young teenage boy in the hall. The boy didn’t have a dad, or at least not one in the troof. And so the elder was suppose to be mentoring the boy.
One day the boy said that the elder pulled his d*ck out, and propositioned the boy. It was just so bizarre that nobody believed him. The elders didn’t even call a JC. The boy (being fatherless) had no status in the hall at all, and so everyone just ignored him.
They remembered what he said though, when a few years later, the cops came to arrest the elder for soliciting sex with a minor (another kid). There was a standoff at his house and shots were fired. But the cops managed to take him alive and now the elder is a registered sex offender.
