An Ohio prosecutor says he will pursue criminal abandonment charges in cases similar to the one in which authorities say a couple gave their 9-year-old adopted son to child welfare officials after raising him from infancy.

Butler County Prosecutor Michael Gmoser (MOH'-zhur) says similar past cases have been handled within the children's services agencies and domestic courts. But he thinks criminal charges should also be considered. He hopes that will serve as a deterrent to adoptive parents who want to return children without justifiable reasons.

A national adoption advocate says the case underscores that adoptive parents have legal obligations.

The suburban Cincinnati couple was indicted on a misdemeanor count each of nonsupport of dependents. They haven't responded to telephone messages.
