A Democratic lawmaker who played a role in the formation of the embattled Tennessee Department of Children's Services says the agency's commissioner shouldn't be blamed for deeply rooted problems she inherited. The agency has released information showing that 31 children it had investigated died during the first half of 2012. Critics want to replace DCS Commissioner Kate O’Day, who Governor Bill Haslam appointed just last year. However, Representative John Deberry of Memphis, who has been a DCS critic over the years, says the problem isn’t O’Day. It’s many of the workers she oversees.
