Going to untrained elders first is stupid. Always go to the authorities first. Never seek advice in child care issues from an elder with a sixth grade education.
If the abuser was a Witness, the response afterward is, "there is an active criminal investigation. I cannot discuss this with you until it is concluded."
If the abuser is found guilty, the elders are in a bind. They can't ignore it even if they want. Take no nonsense from them. If they press you say, "I'm obligated to report this conversation to the investigating officers and to the prosecutor."
