Reports of neglect and abuse that have been investigated and not substantiated shall be kept for five (5) years from the completion date of the investigation and then expunged. If the department has received more than one report on a person, and they are all unsubstantiated, they shall be expunged five (5) years from the completion date of the most recent investigation. Unsubstantiated investigations shall not be expunged if the person has been substantiated as an individual responsible for abuse or neglect in any other investigation. Reports of neglect and abuse that have been investigated and substantiated shall be kept in the department's computerized database and hard copy record indefinitely, regardless of whether or not the person has been determined to pose a risk to the health, safety and well-being of children and has been entered on the central registry.
