Last Officer in Katrina Shootings Heading to Trial Twenty New Orleans police officers have been charged in a series of probes by the Justice Department's civil rights division since 2010. A retired sergeant who was assigned to investigate deadly police shootings on a bridge after Hurricane Katrina will be the last of those officers to get his day in court. A trial is scheduled to start Monday for Gerard Dugue. He is charged with participating in a cover-up to make it appear police were justified in shooting six unarmed people, killing two, on the Danziger Bridge less than a week after the 2005 storm. A judge ordered separate trials for Dugue and five other current or former officers who were convicted in August of civil rights violations stemming from the bridge shootings.
