Which agency handles investigations of child abuse or neglect?

The agency responsible for handling investigations of child abuse or neglect is the Department of Family and Protective Services. This agency's primary role includes protecting children and ensuring their safety and well-being in situations where there are concerns about abuse or neglect. They have trained professionals who investigate reports of child maltreatment, assess the safety of the child, and provide support and services to families.

In contrast, the Department of Public Safety typically deals with broader public safety issues, such as law enforcement and vehicular regulations, while the Federal Bureau of Investigation focuses on federal crimes and broader criminal activities. The Texas Rangers, a division of the Texas Department of Public Safety, conduct investigations into major crimes and provide support to local law enforcement but do not primarily focus on child abuse or neglect cases. Thus, the Department of Family and Protective Services is the most appropriate agency for these specific investigations.
