NEW ORLEANS - A federal judge has postponed the retrial of a retired New Orleans police sergeant charged with helping cover up deadly shootings on a bridge after Hurricane Katrina.

Gerard Dugue's retrial was scheduled to start May 13. U.S. District Judge Kurt Engelhardt didn't immediately set a new date.

Engelhardt said he is waiting to receive more information related to a pretrial motion by Dugue's attorneys.

Dugue's first trial ended in a mistrial when Engelhardt ruled a prosecutor may have unfairly influenced the jury by mentioning the name of a man beaten to death by a New Orleans police officer in an unrelated case.

Police shot six unarmed residents, killing two, on the Danziger Bridge several days after the 2005 storm. Dugue is charged with writing a false report on the shootings.
