The leader of Missouri’s agency responsible for investigating child abuse and neglect says its St. Louis office is making progress in eliminating a massive case backlog.

Last year, St. Louis Public Radio reported on the troubles in the Children’s Division office in St. Louis, which serves the city and St. Louis County. A combination of high turnover and inability to hire people created a backlog of 6,124 cases of abuse or neglect allegations that remained open after 45 days. And the staff’s 16 investigators had an average caseload of 150 — when federal guidelines say it should be closer to 10 to 12.

In a wide-ranging interview on Wednesday, Children’s Division Director Darrell Missey said that increased hiring should play a major role in eliminating overdue cases over the next few months. Missey said the agency is close to reaching its goal of having 60 investigators to look into abuse and neglect claims in St. Louis and St. Louis County.
