There is a chance that some DC government agency had the power to prevent the deaths of the four girls. For example, instead of closing the case after a report about the family’s moving to relatives, the CFSA could at least try to confirm the report and check the possible destination of the family. Besides, the CFSA received several calls into a hotline about this family: one from the nurse and another from the social worker.
This government agency is responsible for protecting children who might be at risk of abuse or parental neglect. The two emergency calls were reported, and it was an obligation of the CFSA to take more serious measures and control the family. Charter schools aim to engage with families for at-home support of education. The local academic facility could send a person for supportive purposes and try to contact a child at least once. In both cases, several persistent activities could probably saved the four girls.
