I did. We had an elder that molested his daughter's best friend when she was 14 years old. The elders in the congregation tried to keep the matter quiet and handled the matter privately. Unfortunately for the BOE, he did not stop the hanky and the panky, and it became a local scandal. Both of them were disfellowshipped, he got divorced from his wife, and married the girl when she was legally old enough.
Did this happen in California? I heard of a similar case. The elder was apparently peeking through a peep hole when the girl undressed ... drugging his wife so she'd be delirious ...
I knew of an MS who had several instances of molestation against him. He first molested a teenager then years later it was discovered he was molesting his wife's niece who was living with them. Eventually he did get disfellowshipped but no legal action was taken against him.
I also know of an elder who was disfellowshipped for molesting several young girls. He moved away and got reinstated. No legal action yet again.
