Missouri child abuse investigators missed warning signs of fentanyl use among parents before their young children died of accidental overdoses from the drug, according to a new state report. It found that Children's Division investigators, who are tasked with following up on claims of abuse and neglect, “lacked essential procedures, missed warning signs and left vulnerable children at risk.” St. Louis Public Radio's Jason Rosenbaum spoke with Department of Social Services director Robert Knodell on how Children's Division could change course after the report.
