HARTFORD, Conn. (AP) Connecticut's Supreme Court has ruled the state Department of Children and Families was justified when it fired a former social worker who was charged with of manslaughter in the death of her own foster child.

Suzanne Listro's union appealed and sought to get her job back after she was acquitted in the 2008 death of 7-month old Michael Brown Jr.

Police had accused her of shaking the child. She said the boy had fallen from a bed.

The court upheld the ruling of an arbitrator, who found that Listro was at least negligent in caring for the child and her actions made her unemployable at an agency responsible for the care and welfare of children.

A message seeking comment was left Friday for Listro's attorney.
