According to Madigan, the social worker saw children in the home both times but determined they were not at imminent risk.
Madigan said there was not enough evidence to keep the case open. She also said the agency offered the mother and family a range of support services over time including parenting advice and educational information about domestic violence.
Madigan said the county is looking at "every single touch we had" with the mother and her nine kids and they are "reviewing everything [they] did." She added, "It is an extremely difficult job.”
The results of the 13 prior investigations are sealed and protected under Ohio law.
