When Wilkins first took office two years ago, investigators had huge caseloads and a nearly 50 percent turnover rate.

DCF recruited more than 100 new investigators to the area, increased salaries by about $8,000 and targeted recruits with investigative skills. The agency also created a tool that helps investigators with critical thinking skills instead of just checking off boxes on a questionnaire.

The changes were prompted after 10-year-old Nubia Barahona was found dead in her adoptive father's truck in 2011.

Child protective investigators never called police in the days after Nubia was missing and were blamed for a hasty investigation and missing red flags that signaled she was in danger.
