The mother of a 7-year-old boy who died after his father allegedly inflicted blunt force trauma to his head has sued Florida's Department of Children and Families, according to the Miami Herald. Custody had been awarded to the father after a prolonged dispute. The father of the child had accused the mother of neglect. The wrongful death lawsuit alleges negligence by the department and its contractors, claiming that child abuse allegations against the father did not receive proper follow-up. The Miami Herald reports that the Broward County sheriff's office is currently investigating the case. To date, no criminal charges have been filed.
