The one elder molester I know for sure was my grandfather. He was indiscriminate in his lechery - boys and girls, I know what he did to me and saw what he did to a (non-witness) girl, which was tame compared to what he must have done in private. Target age was 1 to 12, with a preference for about 5 as far as I could see. He molested most of his own children, though his wife protected one daughter. Messed with his son when very young, but later left him alone because he got "too fat". A male cousin in the household was apparently also spared due to his weight. Sadly, as he would often tell me, he regarded me as "such a beautiful boy".
He's dead, and I'm still alive. Not sure I can take credit for either of those, though.
I looked through my old elementary school pictures the other day. Scary! Each year I look a little more strange and withdrawn. Or maybe I just got less beautiful with age! ;-)
I get the impression that his activities were known by some (other elders) or at least suspected; when later in life I confided to someone what had happened to me I was told, "Oh, I'm not at all surprised - he was molesting his children all the time".
