Attorneys for the Chippewa County Department of Human Services and three of its employees have filed a brief in federal court asking that the case against them be dismissed.
The workers were singled out for the death of a six-month-old boy in 2018.
The attorneys say the agency and its employees acted appropriately when a 10-year-old girl was placed in a foster home with Jaxon Hunter.
She assaulted the infant causing his death.
D-H-S attorneys say daycare operator Amber Sweeney was responsible.
She was outside doing yard work when the girl dropped Jaxon on the floor and stomped on his head.
Sweeney told investigators she hadn’t shown any aggression toward the other children.
