The allegations center on the former superintendent of the Glenwood Resource Center who was fired in December.

The lawsuit claims he conducted medical experimentation. The lawsuit was filed Monday in by two former Glenwood doctors and other former employees. They allege violations of civil rights and whistleblower laws, wrongful termination and interference with a doctor-patient relationship.
