Indianapolis ? A prosecutor said Indiana’s child welfare system failed a 3-year-old girl beaten to death weeks after she was returned to her birth mother, and that foster parents and case workers would be interviewed to find out why.

Marion County Prosecutor Carl Brizzi stopped short Friday of saying Department of Child Services staff acted criminally, but said foster parents of other children have contacted his office to complain that the state agency, despite extensive reforms, continues to place youngsters in danger.

TaJanay Bailey died Tuesday of blunt force trauma to her head, neck and abdomen after authorities say she was repeatedly beaten for wetting her pants and soiling herself.

TaJanay had been in foster care most of her life but was returned to the custody of her mother Oct. 31.
