ST. CROIX — As charges against a 4-year-old boy’s mother and her boyfriend were upgraded to first-degree murder Monday, it was learned that the boy’s father had alerted authorities to the abuse his children were suffering but apparently to no avail.

A V.I. Police affidavit filed in Superior Court reveals that Aaron Benjamin, who was found dead inside his mother’s home Friday, and his younger sister were both victims of a pattern of child abuse.
