Best Herald Writer Carol Marbin Miller The Miami-Dade Regional Juvenile Dentention Center is a dreary place. Lots of kids have hated it over the years, and the Herald has done some pretty good, aggressive stories. But when 17-year-old Omar Paisley died last year of a ruptured appendix, Herald social services writer Carol Marbin Miller picked up the challenge. Soon a grand jury, drawing heavily on Marbin Miller's plethora of stories on the incident, charged two nurses with manslaughter for ignoring the boy when they should have saved him. Later, officials made significant changes at the lockup. Just the latest strike for justice by Marbin Miller, the bane of the state's Department of Juvenile Justice, who has been the champion of every abused kid in the region for several years now.
