The state law of Indiana makes it mandatory for all individuals to report all suspected cases of non-accidental injury, unexplainable failure to thrive, sexual abuse and physical neglect to Child Protection Services of the Department of Family and Children. No one has an option in the matter of reporting such cases for investigation. Reporting in good faith frees the reporter from any liability if the report proves to be unfounded. On the other hand, willful failure to report opens an individual to criminal or civil liability.
