The figures were released late Tuesday by a special team created by Gov. Jan Brewer after more than 6,500 ignored reports came to light in November.
The findings show just how badly the state’s child welfare authorities botched reviews of calls to the state’s abuse hotline.
Most removals came before the uninvestigated cases were discovered, after abuse was reported a second time. But since renewed investigations were launched, 36 cases led to the removal of 69 children.
Brewer removed the state’s Child Protective Services department from its parent agency Monday and set up a new cabinet-level department to handle child welfare.
