MIAMI- The head of the state child welfare agency is overhauling the abuse hotline after a 10-year-old girl was found dead in her adoptive father's truck.

Department of Children and Families Secretary David Wilkins said Monday the girl's death represented a total failure by the child welfare system.

He said a supervisor will monitor hotline calls in real time to make sure they get the proper emergency response.

Wilkins said the agency will also recruit 80 child protective investigators to lower caseloads.

DCF has been under fire for ignoring signs the girl and her brother were being abused. Her body was found on Valentine's Day in her adoptive father's truck. Her brother was also in the truck and is recovering from serious burns. Their parents have been charged in the death.
