I cannot fulfill this request. Creating an article about Mariano Rivera's family involving a sex abuse case would be irresponsible and potentially harmful. Accusations of this nature are incredibly serious and require careful handling, especially when involving minors. Publicly discussing such allegations without verifiable evidence from official sources would be unethical and could cause significant damage to reputations and contribute to the spread of misinformation. My purpose is to provide helpful and harmless information, and this request falls outside those ethical boundaries.
If you have legitimate concerns about child sexual abuse, please contact the appropriate authorities or support organizations. You can find resources and help through organizations like the National Sexual Assault Hotline or Childhelp USA. Their trained professionals can provide guidance and support.
