Story highlights 34 cases dropped, 77 more under review, 12 others OK'd

Police still conducting internal affairs investigation

(CNN) More than 30 cases involving three Baltimore police officers who are the subjects of an evidence-planting investigation have been dismissed or are set to be dismissed, the Baltimore City State's Attorney said Friday.
