About 6,000 cases of child abuse have gone without investigation in the past 4 years.
Officials with the Arizona Child Welfare System say that nearly half of that number were cases received this year.
Many were labeled as misclassfied instead.
That's what state officials said on the state's Senate floor Thursday afternoon.
Gregory McKay, the agency's chief of child welfare investigations, says that a police agency contacted child welfare investigators in August asking for a status report.
That's when problems were exposed.
Department heads say that problems may have come up with hotline system.
Case workers were given too many cases to handle at the same time.
Clarence Carter.. the head of Arizona's Child Welfare system is now asking for another 350 workers in the coming budget.
State representative, Lynne Pancrazi says that budget shouldn't be affecting our childrens' safety.
In the meantime, state officials, as well as many Arizona families, want a solution to the problem.
